From f458192e56b13500ff6eb7c3e94dcf48240f4170 Mon Sep 17 00:00:00 2001 From: Andrew Kelley Date: Fri, 9 Apr 2021 23:17:50 -0700 Subject: [PATCH 001/228] stage2: entry point via std lib and proper updated file detection Instead of Module setting up the root_scope with the root source file, instead, Module relies on the package table graph being set up properly, and inside `update()`, it does the equivalent of `_ = @import("std");`. This, in term, imports start.zig, which has the logic to call main (or not). `Module` no longer has `root_scope` - the root source file is no longer special, it's just in the package table mapped to "root". I also went ahead and implemented proper detection of updated files. mtime, inode, size, and source hash are kept in `Scope.File`. During an update, iterate over `import_table` and stat each file to find out which ones are updated. The source hash is redundant with the source hash used by the struct decl that corresponds to the file, so it should be removed in a future commit before merging the branch. * AstGen: add "previously declared here" notes for variables shadowing decls. * Parse imports as structs. Module now calls `AstGen.structDeclInner`, which is called by `AstGen.containerDecl`. - `importFile` is a bit kludgy with how it handles the top level Decl that kinda gets merged into the struct decl at the end of the function. Be on the look out for bugs related to that as well as possibly cleaner ways to implement this. * Module: factor out lookupDeclName into lookupIdentifier and lookupNa * Rename `Scope.Container` to `Scope.Namespace`. * Delete some dead code. This branch won't work until `usingnamespace` is implemented because it relies on `@import("builtin").OutputMode` and `OutputMode` comes from a `usingnamespace`. --- BRANCH_TODO | 96 +++++ src/AstGen.zig | 184 +++++---- src/Compilation.zig | 98 ++--- src/Module.zig | 678 +++++++++++++++++++------------- src/Sema.zig | 139 +++---- src/codegen.zig | 4 +- src/link/Elf.zig | 4 +- src/link/MachO/DebugSymbols.zig | 4 +- src/type.zig | 35 +- test/stage2/test.zig | 22 +- 10 files changed, 757 insertions(+), 507 deletions(-) create mode 100644 BRANCH_TODO diff --git a/BRANCH_TODO b/BRANCH_TODO new file mode 100644 index 0000000000..04b876c8b0 --- /dev/null +++ b/BRANCH_TODO @@ -0,0 +1,96 @@ + * get rid of failed_root_src_file + + + const container_name_hash: Scope.NameHash = if (found_pkg) |pkg| + pkg.namespace_hash + else + std.zig.hashName(cur_pkg.namespace_hash, "/", resolved_path); + + file_scope.* = .{ + .root_container = .{ + .parent = null, + .file_scope = file_scope, + .decls = .{}, + .ty = struct_ty, + .parent_name_hash = container_name_hash, + }, + }; + mod.analyzeContainer(&file_scope.root_container) catch |err| switch (err) { + error.AnalysisFail => { + assert(mod.comp.totalErrorCount() != 0); + }, + else => |e| return e, + }; + return file_scope; + + + + // Until then we simulate a full cache miss.

This is necessary because we want to reuse the same immutable ZIR code for multiple generic instantiations (and comptime function calls). * AstGen: fix using members_len instead of fields_len for struct decls. * structs: the struct_decl ZIR instruction is now also a block. This is so that the type expressions, default field value expressions, and alignment expressions can be evaluated in a scope that contains the decls from the struct namespace itself. * Add "std" and "builtin" packages to the builtin package. * Don't try to build glibc, musl, or mingw-w64 when using `-ofmt=c`. * builtin.zig is generated without `usingnamespace`. * builtin.zig takes advantage of `std.zig.fmtId` for CPU features. * A first pass at implementing `usingnamespace`. It's problematic and should either be deleted, or polished, before merging this branch. * Sema: allow explicitly specifying the namespace in which to look up Decls. This is used by `struct_decl` in order to put the decls from the struct namespace itself in scope when evaluating the type expressions, default value expressions, and alignment expressions. * Module: fix `analyzeNamespace` assuming that it is the top-level root declaration node. * Sema: implement comptime and runtime cmp operator. * Sema: implement peer type resolution for enums and enum literals. * Pull in the changes from master branch: 262e09c482d98a78531c049a18b7f24146fe157f. * ZIR: complete out simple_ptr_type debug printing --- BRANCH_TODO | 5 + build.zig | 2 +- src/AstGen.zig | 64 ++++++---- src/Compilation.zig | 44 ++++--- src/Module.zig | 140 +++++++++++++++++++-- src/Sema.zig | 252 +++++++++++++++++++++++++++---------- src/codegen/spirv/spec.zig | 2 +- src/link.zig | 2 +- src/stage1/codegen.cpp | 42 ++++--- src/value.zig | 27 ++-- src/zir.zig | 46 ++++++- test/tests.zig | 2 +- 12 files changed, 475 insertions(+), 153 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 04b876c8b0..2bfdec7b5e 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -1,4 +1,8 @@ * get rid of failed_root_src_file + * handle decl collision with usingnamespace + * the decl doing the looking up needs to create a decl dependency + on each usingnamespace decl + * handle usingnamespace cycles const container_name_hash: Scope.NameHash = if (found_pkg) |pkg| @@ -94,3 +98,4 @@ fn getAnonTypeName(mod: *Module, scope: *Scope, base_token: std.zig.ast.TokenInd return std.fmt.allocPrint(mod.gpa, "{s}:{d}:{d}", .{ base_name, loc.line, loc.column });

The C object compilation tasks are moved to be spawned after AstGen, since they only need to complete by the end of the function. With this commit, the codebase compiles, but much more reworking is needed to get things back into a useful state. --- BRANCH_TODO | 1118 +++++++++++++++++++++++++++++ src/AstGen.zig | 1665 ++++++++++++++++++++++++++++--------------- src/Compilation.zig | 153 ++-- src/Module.zig | 1603 +++++++++-------------------------------- src/Sema.zig | 25 +- src/Zir.zig | 141 +++- 6 files changed, 2758 insertions(+), 1947 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 2bfdec7b5e..73379f129b 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -4,6 +4,13 @@ on each usingnamespace decl * handle usingnamespace cycles + * have failed_trees and just put the file in there + - this way we can emit all the parse errors not just the first one + - but maybe we want just the first one? + + * need a var decl zir instruction which includes the name because we need to do the + compile error for a local shadowing a decl with Sema looking up the decl name. + - this means LocalVal and LocalPtr should use the string table const container_name_hash: Scope.NameHash = if (found_pkg) |pkg| pkg.namespace_hash @@ -99,3 +106,1114 @@ fn getAnonTypeName(mod: *Module, scope: *Scope, base_token: std.zig.ast.TokenInd } + // Detect which source files changed. + for (module.import_table.items()) |entry| { + const file = entry.value; + var f = try file.pkg.root_src_directory.handle.openFile(file.sub_file_path, .{}); + defer f.close(); + + // TODO handle error here by populating a retryable compile error + const stat = try f.stat(); + const unchanged_metadata = + stat.size == file.stat_size and + stat.mtime == file.stat_mtime and + stat.inode == file.stat_inode; + + if (unchanged_metadata) { + log.debug("unmodified metadata of file: {s}", .{file.sub_file_path}); + continue; + } + + log.debug("metadata changed: {s}", .{file.sub_file_path}); + if (file.status == .unloaded_parse_failure) { + module.failed_files.swapRemove(file).?.value.destroy(module.gpa); + } + + file.unload(module.gpa); + // TODO handle error here by populating a retryable compile error + try file.finishGettingSource(module.gpa, f, stat); + + module.analyzeFile(file) catch |err| switch (err) { + error.OutOfMemory => return error.OutOfMemory, + error.AnalysisFail => continue, + else => |e| return e, + }; + } + + + + const parent_name_hash: Scope.NameHash = if (found_pkg) |pkg| + pkg.namespace_hash + else + std.zig.hashName(cur_pkg.namespace_hash, "/", resolved_path); + + // We need a Decl to pass to AstGen and collect dependencies.

These are replaced by `decl_ref_named` and `decl_val_named`, respectively, which will probably get renamed in the future to the instructions that were just deleted. * AstGen: implement `@This()`, `@fence()`, `@returnAddress()`, and `@src()`. * AstGen: struct_decl improved to support fields_len=0 but have decls. * AstGen: fix missing null bytes after compile error messages. * SrcLoc: no longer depend on `Decl`. Instead have an explicit field `parent_decl_node` which is an absolute AST Node index. * Module: `failed_files` table can have null value, in which case the key, which is a `*Scope.File`, will have ZIR errors in it. * ZIR: implement text rendering of struct decls. * CLI: introduce debug_usage and `zig astgen` command which is enabled when the compiler is built in debug mode. --- BRANCH_TODO | 11 +++ src/AstGen.zig | 60 +++++++----- src/Compilation.zig | 69 ++++++++++++-- src/Module.zig | 220 ++++++++++++++++++------------------------- src/Sema.zig | 41 ++++---- src/Zir.zig | 222 +++++++++++++++++++++++++++----------------- src/main.zig | 99 ++++++++++++++++++-- 7 files changed, 458 insertions(+), 264 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 56c2db0853..4b906b3945 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -1,3 +1,14 @@ + * AstGen decls into blocks so we can evaluate them independently + * look for cached zir code + * save zir code to cache + * store list of imported strings + * use list of imported strings to queue up more astgen tasks + * keep track of file dependencies/dependants + * unload files from memory when a dependency is dropped + * implement zir error notes + + * implement the new AstGen compile errors + * get rid of failed_root_src_file * get rid of Scope.DeclRef * handle decl collision with usingnamespace diff --git a/src/AstGen.zig b/src/AstGen.zig index 9e4b4cac0b..1091517494 100644 --- a/src/AstGen.zig +++ b/src/AstGen.zig @@ -96,14 +96,18 @@ pub fn generate(gpa: *Allocator, file: *Scope.File) InnerError!Zir { .arg = 0, }, };

specify a tag type. `extern enum` is only when you need tags to alias. But aliasing tags is a smell. I will be making a proposal shortly to remove `extern enum` from the language. * there is no such thing as `packed enum`. * instead of `catch |_|`, omit the capture entirely. * unused function definition with missing parameter name * using `try` outside of a function or test --- BRANCH_TODO | 2 ++ lib/std/array_hash_map.zig | 2 +- lib/std/crypto/25519/edwards25519.zig | 6 +++--- lib/std/crypto/utils.zig | 12 ++++++------ lib/std/elf.zig | 4 ++-- lib/std/fmt.zig | 28 +++++++++++++-------------- lib/std/json.zig | 4 ++-- lib/std/macho.zig | 10 +++++----- lib/std/mem.zig | 2 +- lib/std/meta.zig | 4 ---- lib/std/os/bits/darwin.zig | 8 ++++---- lib/std/os/bits/dragonfly.zig | 6 +++--- lib/std/os/bits/freebsd.zig | 6 +++--- lib/std/os/bits/haiku.zig | 8 ++++---- lib/std/os/bits/linux.zig | 16 +++++++-------- lib/std/os/bits/linux/arm-eabi.zig | 2 +- lib/std/os/bits/linux/arm64.zig | 2 +- lib/std/os/bits/linux/i386.zig | 2 +- lib/std/os/bits/linux/mips.zig | 2 +- lib/std/os/bits/linux/netlink.zig | 9 +++++---- lib/std/os/bits/linux/powerpc.zig | 2 +- lib/std/os/bits/linux/powerpc64.zig | 4 ++-- lib/std/os/bits/linux/prctl.zig | 2 +- lib/std/os/bits/linux/riscv64.zig | 2 +- lib/std/os/bits/linux/sparc64.zig | 2 +- lib/std/os/bits/linux/x86_64.zig | 3 +-- lib/std/os/bits/netbsd.zig | 8 ++++---- lib/std/os/bits/openbsd.zig | 6 +++--- lib/std/os/linux.zig | 2 -- lib/std/os/uefi/status.zig | 2 +- lib/std/os/windows/bits.zig | 6 +++--- lib/std/os/windows/ntstatus.zig | 2 +- lib/std/os/windows/win32error.zig | 2 +- lib/std/os/windows/ws2_32.zig | 2 +- lib/std/pdb.zig | 4 ++-- lib/std/valgrind.zig | 8 ++++---- lib/std/valgrind/callgrind.zig | 2 +- lib/std/valgrind/memcheck.zig | 4 ++-- src/AstGen.zig | 4 +++- src/Compilation.zig | 2 +- 40 files changed, 101 insertions(+), 103 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 8a0bfd1b5f..334b75fe75 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -32,6 +32,8 @@ compile error for a local shadowing a decl with Sema looking up the decl name. - this means LocalVal and LocalPtr should use the string table + * sort compile errors before presenting them to eliminate nondeterministic error reporting + const container_name_hash: Scope.NameHash = if (found_pkg) |pkg| pkg.namespace_hash else diff --git a/lib/std/array_hash_map.zig b/lib/std/array_hash_map.zig index 9b0c53b18a..1dc4110c75 100644 --- a/lib/std/array_hash_map.zig +++ b/lib/std/array_hash_map.zig @@ -1310,7 +1310,7 @@ test "reIndex" { } test "fromOwnedArrayList" { - comptime const array_hash_map_type = AutoArrayHashMap(i32, i32);

Allows adding/removing a field without possibility of accidentally introducing a bug of forgetting to set the new field. * Add to GenZir `nosuspend_node` and `suspend_node` in preparation for implementing `suspend` blocks and `nosuspend` blocks. * AstGen: fix assembly to support clobbers, multiple outputs, and outputs without `->` syntax. - `asm` and `asm_volatile` move to `Extended` enum with `small` being repurposed for a few things. This frees up 2 ZIR tags, 1 of which is used in this commit and 1 is leftover. * AstGen: fix `simple_types` incorrectly having multiple conflicting values for "undefined" and "null". - Also add "anyframe" to `simple_types`. * Add `anyframe_type` to type.zig, value.zig and `Zir.Inst.Ref`. - Also add i128 and u128 types to `Zir.Inst.Ref` and `simple_types`. * Sema/Zir: Fix incorrect math causing the function body to be messed up for Extended-encoded functions. * Zir: support `i32` fields for "extra" payloads. --- src/AstGen.zig | 422 ++++++++++++++++++------------------------------- src/Module.zig | 97 +++++++++++- src/Sema.zig | 85 +++++++--- src/Zir.zig | 210 +++++++++++++++++------- src/type.zig | 44 +++++- src/value.zig | 23 ++- 6 files changed, 515 insertions(+), 366 deletions(-) diff --git a/src/AstGen.zig b/src/AstGen.zig index 9b957a8d4f..7e3eff48ea 100644 --- a/src/AstGen.zig +++ b/src/AstGen.zig @@ -723,8 +723,12 @@ pub fn expr(gz: *GenZir, scope: *Scope, rl: ResultLoc, node: ast.Node.Index) Inn }, .enum_literal => return simpleStrTok(gz, scope, rl, main_tokens[node], node, .enum_literal), .error_value => return simpleStrTok(gz, scope, rl, node_datas[node].rhs, node, .error_value), - .anyframe_literal => return astgen.failNode(node, "async and related features are not yet supported", .{}), - .anyframe_type => return astgen.failNode(node, "async and related features are not yet supported", .{}), + .anyframe_literal => return rvalue(gz, scope, rl, .anyframe_type, node), + .anyframe_type => { + const return_type = try typeExpr(gz, scope, node_datas[node].rhs);

Also inside a comptime block, emit function calls as comptime calls. Also emit `async foo()` calls as async calls. Remove compile error for `nosuspend` block inside `suspend` block. Instead of implicitly treating every `suspend` block also as a `nosuspend` block (which would make sense), we leave suspension points as compile errors, to hint to the programmer about accidents. Of course they may then assert `nosuspend` by introducing a block within their suspend block. To make room in `Zir.Inst.Tag` I moved `typeof_peer` and `compile_log` to `Extended`. --- BRANCH_TODO | 1 - src/AstGen.zig | 41 ++++++++++++----------------- src/Module.zig | 33 ++++++++++++++++++++++++ src/Sema.zig | 42 ++++++++++++++++++------------ src/Zir.zig | 70 ++++++++++++++++++++++++++++++-------------------- 5 files changed, 118 insertions(+), 69 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 39c860260f..c24172727d 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -37,7 +37,6 @@ * when handling decls, catch the error and continue, so that AstGen can report more than one compile error. - * AstGen: inside a nosuspend block, emit function calls as nosuspend calls * AstGen: add result location pointers to function calls const container_name_hash: Scope.NameHash = if (found_pkg) |pkg| diff --git a/src/AstGen.zig b/src/AstGen.zig index 88cddc39b9..5994ca0d7f 100644 --- a/src/AstGen.zig +++ b/src/AstGen.zig @@ -900,11 +900,6 @@ pub fn nosuspendExpr( try astgen.errNoteNode(gz.nosuspend_node, "other nosuspend block here", .{}), });

I think it would make sense to start decoupling AstGen from the rest of the compiler code, similar to how the tokenizer and parser are decoupled. * AstGen: For decls, move the block_inline instructions to the top of the function so that they get lower ZIR instruction indexes. With this, the block_inline instruction index combined with its corresponding break_inline instruction index can be used to form a ZIR instruction range. This is useful for allocating an array to map ZIR instructions to semantically analyzed instructions. * Module: extract emit-h functionality into a struct, and only allocate it when emit-h is activated. * Module: remove the `decl_table` field. This previously was a table of all Decls in the entire Module. A "name hash" strategy was used to find decls within a given namespace, using this global table. Now, each Namespace has its own map of name to children Decls. - Additionally, there were 3 places that relied on iterating over decl_table in order to function: - C backend and SPIR-V backend. These now have their own decl_table that they keep populated when `updateDecl` and `removeDecl` are called. - emit-h. A `decl_table` field has been added to the new GlobalEmitH struct which is only allocated when emit-h is activated. * Module: fix ZIR serialization/deserialization bug in debug mode having to do with the secret safety tag for untagged unions. There is still an open TODO to investigate a friendlier solution to this problem with the language. * Module: improve deserialization of ZIR to allocate only exactly as much capacity as length in the instructions array so as to not waste space. * Module: move `srcHashEql` to `std.zig` to live next to the definition of `SrcHash` itself. * Module: re-introduce the logic for scanning top level declarations within a namespace. * Compilation: add an `analyze_pkg` Job which is used to kick off the start of semantic analysis by doing the equivalent of `_ = @import("std");`. The `analyze_pkg` job is unconditionally added to the work queue on every update(), with pkg set to the std lib pkg. * Rename TZIR to AIR in a few places. A more comprehensive rename will come later. --- BRANCH_TODO | 359 ++++------------------ lib/std/zig.zig | 4 + src/AstGen.zig | 21 +- src/Compilation.zig | 63 +++- src/Module.zig | 703 ++++++++++++++++++++------------------------ src/Sema.zig | 78 ++--- src/link/C.zig | 38 ++- src/link/SpirV.zig | 17 +- 8 files changed, 493 insertions(+), 790 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 83f973cad6..5e45a3d7da 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -1,3 +1,6 @@ + * reimplement semaDecl + * use a hash map for instructions because the array is too big + * keep track of file dependencies/dependants * unload files from memory when a dependency is dropped @@ -5,6 +8,7 @@ * get rid of failed_root_src_file * get rid of Scope.DeclRef + * get rid of NameHash * handle decl collision with usingnamespace * the decl doing the looking up needs to create a decl dependency on each usingnamespace decl @@ -35,58 +39,6 @@ * AstGen: add result location pointers to function calls * nested function decl: how to refer to params? - * detect when to put cached ZIR into the local cache instead of the global one - - const container_name_hash: Scope.NameHash = if (found_pkg) |pkg| - pkg.namespace_hash - else - std.zig.hashName(cur_pkg.namespace_hash, "/", resolved_path); - - file_scope.* = .{ - .root_container = .{ - .parent = null, - .file_scope = file_scope, - .decls = .{}, - .ty = struct_ty, - .parent_name_hash = container_name_hash, - }, - }; - mod.analyzeContainer(&file_scope.root_container) catch |err| switch (err) { - error.AnalysisFail => { - assert(mod.comp.totalErrorCount() != 0); - }, - else => |e| return e, - }; - return file_scope; - - - - // Until then we simulate a full cache miss.

This allows codegen to emit debug info without having the source bytes, tokens, or AST nodes loaded in memory. * ZIR: each decl has the absolute line number. This allows computing line numbers from offsets without consulting source code bytes. Memory management: creating a function definition does not prematurely set the Decl arena. Instead the function is allocated with the general purpose allocator. Codegen no longer looks at source code bytes for any reason. They can remain unloaded from disk. --- BRANCH_TODO | 1 - src/AstGen.zig | 73 +++++++++++++++++++++++++++++++------ src/Module.zig | 95 ++++++++++++++++++++++++++++++++++++++++-------- src/Sema.zig | 50 ++++++++++++++----------- src/Zir.zig | 63 ++++++++++++++++++++++++++++---- src/codegen.zig | 66 +++++++++++---------------------- src/ir.zig | 3 +- src/link/Elf.zig | 32 ++-------------- 8 files changed, 253 insertions(+), 130 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 7b625204f6..3594632ea1 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -1,4 +1,3 @@ - * modify dbg_stmt ZIR instructions to have line/column rather than node indexes * decouple AstGen from Module, Compilation * AstGen threadlocal * extern "foo" for vars and for functions diff --git a/src/AstGen.zig b/src/AstGen.zig index 1c75a12069..b5b31c4095 100644 --- a/src/AstGen.zig +++ b/src/AstGen.zig @@ -94,6 +94,7 @@ pub fn generate(gpa: *Allocator, file: *Scope.File) InnerError!Zir { .force_comptime = true, .parent = &file.base, .decl_node_index = 0, + .decl_line = 0, .astgen = &astgen, };

The ZIR code uses the special `Ref.export_options` value, and semantic analysis has to map this to the corresponding type from `std.builtin`. --- src/Module.zig | 154 ++++++++++++++++++++++++++++++++++++- src/Sema.zig | 203 ++++++++++++++++++------------------------------- src/Zir.zig | 4 +- 3 files changed, 225 insertions(+), 136 deletions(-) diff --git a/src/Module.zig b/src/Module.zig index 57bb2435fb..f780dfb9f6 100644 --- a/src/Module.zig +++ b/src/Module.zig @@ -493,9 +493,10 @@ pub const Struct = struct { fields: std.StringArrayHashMapUnmanaged(Field), /// Represents the declarations inside this struct. namespace: Scope.Namespace, - /// Offset from `owner_decl`, points to the struct AST node. node_offset: i32, + /// Index of the struct_decl ZIR instruction. + zir_index: Zir.Inst.Index, layout: std.builtin.TypeInfo.ContainerLayout, status: enum { @@ -2406,6 +2407,8 @@ pub fn semaFile(mod: *Module, file: *Scope.File) InnerError!void { } assert(file.zir_loaded); + const main_struct_inst = file.zir.extra[@enumToInt(Zir.ExtraIndex.main_struct)] - + @intCast(u32, Zir.Inst.Ref.typed_value_map.len); const gpa = mod.gpa; var new_decl_arena = std.heap.ArenaAllocator.init(gpa); @@ -2418,6 +2421,7 @@ pub fn semaFile(mod: *Module, file: *Scope.File) InnerError!void { .owner_decl = undefined, // set below .fields = .{}, .node_offset = 0, // it's the struct for the root file + .zir_index = main_struct_inst, .layout = .Auto, .status = .none, .namespace = .{ @@ -2468,8 +2472,6 @@ pub fn semaFile(mod: *Module, file: *Scope.File) InnerError!void { }; defer block_scope.instructions.deinit(gpa); - const main_struct_inst = file.zir.extra[@enumToInt(Zir.ExtraIndex.main_struct)] - - @intCast(u32, Zir.Inst.Ref.typed_value_map.len); try sema.analyzeStructDecl(new_decl, main_struct_inst, struct_obj); try new_decl.finalizeNewArena(&new_decl_arena); @@ -4060,3 +4062,149 @@ pub const SwitchProngSrc = union(enum) { } else unreachable; } }; + +pub fn analyzeStructFields(mod: *Module, struct_obj: *Module.Struct) InnerError!void { + const tracy = trace(@src()); + defer tracy.end(); + + const gpa = mod.gpa; + const zir = struct_obj.owner_decl.namespace.file_scope.zir; + const inst_data = zir.instructions.items(.data)[struct_obj.zir_index].pl_node; + const src = inst_data.src(); + const extra = zir.extraData(Zir.Inst.StructDecl, inst_data.payload_index); + const fields_len = extra.data.fields_len; + const decls_len = extra.data.decls_len; + + // Skip over decls. + var extra_index = extra.end; + { + const bit_bags_count = std.math.divCeil(usize, decls_len, 8) catch unreachable; + var bit_bag_index: usize = extra_index; + extra_index += bit_bags_count; + var cur_bit_bag: u32 = undefined; + var decl_i: u32 = 0; + while (decl_i < decls_len) : (decl_i += 1) { + if (decl_i % 8 == 0) { + cur_bit_bag = zir.extra[bit_bag_index]; + bit_bag_index += 1; + } + const flags = @truncate(u4, cur_bit_bag); + cur_bit_bag >>= 4; + + extra_index += 7; // src_hash(4) + line(1) + name(1) + value(1) + extra_index += @truncate(u1, flags >> 2); + extra_index += @truncate(u1, flags >> 3); + } + } + + const body = zir.extra[extra_index..][0..extra.data.body_len]; + if (fields_len == 0) { + assert(body.len == 0); + return; + } + extra_index += body.len; + + var decl_arena = struct_obj.owner_decl.value_arena.?.promote(gpa); + defer struct_obj.owner_decl.value_arena.?.* = decl_arena.state; + + try struct_obj.fields.ensureCapacity(&decl_arena.allocator, fields_len); + + // We create a block for the field type instructions because they + // may need to reference Decls from inside the struct namespace. + // Within the field type, default value, and alignment expressions, the "owner decl" + // should be the struct itself.

Instead, Sema code should call one of these two: - `resolvePossiblyUndefinedValue` (followed by logic dealing with undefined values) - `resolveDefinedValue` (a compile error will be emitted if the value is undefined) * An exported function with an unspecified calling convention gets the C calling convention. * Implement comptime field access for structs. * Add another implementation of "type has one possible value" in Sema. This is a bit unfortunate since the logic is duplicated, but the one in Type asserts that the types are resolved already, and is appropriate to call from codegen, while the one in Sema performs type resolution if necessary, reporting any compile errors that occur in the process. --- BRANCH_TODO | 4 - src/Module.zig | 238 ++++++++++++++++++++++++++++++--- src/Sema.zig | 353 ++++++++++++++++++++++++++++++++++++++++++++----- src/ir.zig | 3 + src/type.zig | 122 ++++++++++++++--- src/value.zig | 57 ++++++++ 6 files changed, 705 insertions(+), 72 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 87fd335803..19d43daacb 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -1,4 +1,3 @@ - * start.zig should support pub export fn main with -ofmt=c * get stage2 tests passing * modify stage2 tests so that only 1 uses _start and the rest use pub fn main @@ -61,6 +60,3 @@ * AstGen threadlocal * extern "foo" for vars - - * TODO all decls should probably store source hash.

they can just store the value directly. - This required making memory management a bit more sophisticated to detect when a Decl owns the Namespace associated with it, for the purposes of deinitialization. * Decl.name and Namespace decl table keys no longer directly reference ZIR; instead they have heap-duped names, so that deleted decls, which no longer have any ZIR to reference for their names, can be removed from the parent Namespace table. - In the future I would like to explore going a different direction with this, where the strings would still point to the ZIR however they would be removed from their owner Namespace objects during the update detection. The design principle here is that the existence of incremental compilation as a feature should not incur any cost for the use case when it is not used. In this example Decl names could simply point to ZIR string table memory, and it is only because of incremental compilation that we duplicate their names. * AstGen: implement threadlocal variables * CLI: call cleanExit after building a compilation so that in release modes we don't bother freeing memory or closing file descriptors, allowing the OS to do it more efficiently. * Avoid calling `freeDecl` in the linker for unreferenced Decl objects. * Fix CBE test case expecting the compile error to point to the wrong column. --- BRANCH_TODO | 5 +- src/AstGen.zig | 4 + src/Module.zig | 179 ++++++++++++++++++++++---------------------- src/Sema.zig | 57 +++++++++++++- src/Zir.zig | 3 +- src/main.zig | 2 + src/value.zig | 8 -- test/stage2/cbe.zig | 2 +- 8 files changed, 157 insertions(+), 103 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 19d43daacb..54153185e2 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -58,5 +58,8 @@ natural alignment for fields and do not have any comptime fields. this will save 16 bytes per struct field in the compilation. - * AstGen threadlocal * extern "foo" for vars + + * use ZIR memory for decl names where possible and also for keys + - this will require more sophisticated changelist detection which does some + pre-emptive deletion of decls from the parent namespace diff --git a/src/AstGen.zig b/src/AstGen.zig index 77846c4732..32220948a3 100644 --- a/src/AstGen.zig +++ b/src/AstGen.zig @@ -3009,6 +3009,7 @@ fn globalVarDecl( .align_inst = .none, // passed via the decls data .init = init_inst, .is_extern = false, + .is_threadlocal = is_threadlocal, }); break :vi var_inst; } else { @@ -3026,6 +3027,7 @@ fn globalVarDecl( .align_inst = .none, // passed via the decls data .init = .none, .is_extern = true, + .is_threadlocal = is_threadlocal, }); break :vi var_inst; } else { @@ -8100,6 +8102,7 @@ const GenZir = struct { var_type: Zir.Inst.Ref, init: Zir.Inst.Ref, is_extern: bool, + is_threadlocal: bool, }) !Zir.Inst.Ref { const astgen = gz.astgen; const gpa = astgen.gpa; @@ -8137,6 +8140,7 @@ const GenZir = struct { .has_align = args.align_inst != .none, .has_init = args.init != .none, .is_extern = args.is_extern, + .is_threadlocal = args.is_threadlocal, }), .operand = payload_index, } }, diff --git a/src/Module.zig b/src/Module.zig index 3d0f22b46c..0601245db3 100644 --- a/src/Module.zig +++ b/src/Module.zig @@ -154,9 +154,7 @@ pub const DeclPlusEmitH = struct { }; pub const Decl = struct { - /// For declarations that have corresponding source code, this is identical to - /// `getName().?`.

Here's the enum reproduced in the commit message for convenience: ```zig pub const NameStrategy = enum(u2) { /// Use the same name as the parent declaration name. /// e.g. `const Foo = struct {...};`. parent, /// Use the name of the currently executing comptime function call, /// with the current parameters. e.g. `ArrayList(i32)`. func, /// Create an anonymous name for this declaration. /// Like this: "ParentDeclName_struct_69" anon, }; ``` With this information in the ZIR, a future commit can improve the names of structs, unions, enums, and opaques. In order to accomplish this, the following ZIR instruction forms were removed and replaced with Extended op codes: * struct_decl * struct_decl_packed * struct_decl_extern * union_decl * union_decl_packed * union_decl_extern * enum_decl * enum_decl_nonexhaustive By being extended opcodes, one more u32 is needed, however we more than make up for it by repurposing the 16 "small" bits to provide shorter encodings for when decls_len == 0, fields_len == 0, a source node is not provided, etc. There tends to be no downside, and in fact sometimes upsides, to using an extended op code when there is a need for flag bits, which is the case for all three of these. Likewise, the container layout can be encoded in these bits rather than into the opcode. The following 4 ZIR instructions were added, netting a total of 4 freed up ZIR enum tags for future use: * opaque_decl_anon * opaque_decl_func * error_set_decl_anon * error_set_decl_func This is so that opaques and error sets can have the same name hint as structs, enums, and unions. `std.builtin.ContainerLayout` gets an explicit integer tag type so that it can be used inside packed structs. This commit also makes `Module.Namespace` use a separate set for anonymous decls, thus allowing anonymous decls to share the same `Decl.name` as their owner `Decl` objects. --- BRANCH_TODO | 3 + lib/std/builtin.zig | 2 +- src/AstGen.zig | 301 +++++++++++++++++----- src/Module.zig | 149 +++++++---- src/Sema.zig | 151 +++++++---- src/Zir.zig | 591 +++++++++++++++++++++++++++----------------- 6 files changed, 808 insertions(+), 389 deletions(-) diff --git a/BRANCH_TODO b/BRANCH_TODO index 28a611d809..76b4f7e1aa 100644 --- a/BRANCH_TODO +++ b/BRANCH_TODO @@ -65,3 +65,6 @@ * use ZIR memory for decl names where possible and also for keys - this will require more sophisticated changelist detection which does some pre-emptive deletion of decls from the parent namespace + + * better anonymous Decl naming convention + - avoid the global atomic integer for the number because of contention diff --git a/lib/std/builtin.zig b/lib/std/builtin.zig index 518a971430..4d9350bbdd 100644 --- a/lib/std/builtin.zig +++ b/lib/std/builtin.zig @@ -263,7 +263,7 @@ pub const TypeInfo = union(enum) { /// This data structure is used by the Zig language code generation and /// therefore must be kept in sync with the compiler implementation. - pub const ContainerLayout = enum { + pub const ContainerLayout = enum(u2) { Auto, Extern, Packed, diff --git a/src/AstGen.zig b/src/AstGen.zig index 7d52fd9cf4..f445f3dd26 100644 --- a/src/AstGen.zig +++ b/src/AstGen.zig @@ -85,6 +85,7 @@ pub fn generate(gpa: *Allocator, tree: ast.Tree) InnerError!Zir { var gen_scope: GenZir = .{ .force_comptime = true, .parent = null, + .anon_name_strategy = .parent, .decl_node_index = 0, .decl_line = 0, .astgen = &astgen, @@ -105,7 +106,7 @@ pub fn generate(gpa: *Allocator, tree: ast.Tree) InnerError!Zir { &gen_scope.base, 0, container_decl, - .struct_decl, + .Auto, )) |struct_decl_ref| { astgen.extra.items[@enumToInt(Zir.ExtraIndex.main_struct)] = @enumToInt(struct_decl_ref);

This maps more cleanly to the actual ownership, since the `File` does own the root decl, but it does not directly own the `Namespace`. * `semaFile` completes the creation of the `Decl` even when semantic analysis fails. The `analysis` field of the `Decl` will contain the results of semantic analysis. This prevents cleaning up of memory still referenced by other Decl objects. * `semaDecl` sets `Struct.zir_index` of the root struct decl, which fixes use of undefined value in case the first update contained a ZIR compile error. --- src/Module.zig | 38 +++++++++++++++++++++----------------- src/Sema.zig | 4 ++-- src/main.zig | 4 ++-- 3 files changed, 25 insertions(+), 21 deletions(-) diff --git a/src/Module.zig b/src/Module.zig index 3a877ad9e4..6dc8de90aa 100644 --- a/src/Module.zig +++ b/src/Module.zig @@ -822,7 +822,7 @@ pub const Scope = struct { pub fn namespace(scope: *Scope) *Namespace { switch (scope.tag) { .block => return scope.cast(Block).?.sema.owner_decl.namespace, - .file => return scope.cast(File).?.namespace.?, + .file => return scope.cast(File).?.root_decl.?.namespace, .namespace => return scope.cast(Namespace).?, .decl_ref => return scope.cast(DeclRef).?.decl.namespace, } @@ -998,10 +998,8 @@ pub const Scope = struct { zir: Zir, /// Package that this file is a part of, managed externally. pkg: *Package, - /// The namespace of the struct that represents this file. - /// Populated only when `have_decl` is true. - /// Owned by its owner Decl Value. - namespace: ?*Namespace, + /// The Decl of the struct that represents this File. + root_decl: ?*Decl, /// Used by change detection algorithm, after astgen, contains the /// set of decls that existed in the previous ZIR but not in the new one. @@ -1049,8 +1047,8 @@ pub const Scope = struct { log.debug("deinit File {s}", .{file.sub_file_path}); file.deleted_decls.deinit(gpa); file.outdated_decls.deinit(gpa); - if (file.namespace) |ns| { - ns.getDecl().destroy(mod); + if (file.root_decl) |root_decl| { + root_decl.destroy(mod); } gpa.free(file.sub_file_path); file.unload(gpa); @@ -2576,11 +2574,11 @@ pub fn astGenFile(mod: *Module, file: *Scope.File, prog_node: *std.Progress.Node gpa.destroy(file_prev_zir); file.prev_zir = null; try updateZirRefs(gpa, file, prev_zir); - } else if (file.namespace) |ns| { + } else if (file.root_decl) |root_decl| { // First time the File has succeeded ZIR.

When they get referenced, they get semantically analyzed. Before this commit, when they got unreferenced, they were completely deleted, including deleted from the containing Namespace. However, if the update did not cause the containing Namespace to get deleted, for example, if `std.builtin.ExportOptions` is no longer referenced, but `std.builtin` is still referenced, and then `ExportOptions` gets referenced again, the Namespace would be incorrectly missing the Decl, so we get an incorrect "no such member" error. The solution is to, when dealing with a no longer referenced Decl objects during an update, clear them to the state they would be in on a fresh scanDecl, rather than completely deleting them. --- src/Compilation.zig | 12 ++++- src/Module.zig | 108 +++++++++++++++++++++++++++---------------- test/stage2/test.zig | 49 +++++++++----------- 3 files changed, 102 insertions(+), 67 deletions(-) diff --git a/src/Compilation.zig b/src/Compilation.zig index a5c365fa40..0b77d8ee02 100644 --- a/src/Compilation.zig +++ b/src/Compilation.zig @@ -1620,13 +1620,21 @@ pub fn update(self: *Compilation) !void { if (!use_stage1) { if (self.bin_file.options.module) |module| { // Process the deletion set.

However we still want to avoid bloat in the installation size, so we blank them out instead of omitting them entirely.
