Now that `@import` of a non-existent file name is a compile error, the
Zig installation needs to include files that end with test.zig. However
we still want to avoid bloat in the installation size, so we blank them
out instead of omitting them entirely.
Now AstGen of the full standard library can complete successfully on a
Zig installation rather than erroring out with file not found.
Conflicts:
* build.zig
* src/Compilation.zig
* src/codegen/spirv/spec.zig
* src/link/SpirV.zig
* test/stage2/darwin.zig
- this one might be problematic; start.zig looks for `main` in the
root source file, not `_main`. Not sure why there is an underscore
there in master branch.
* `-lc++` now implies `-lc`.
* `-lunwind` is now pulled out into a separate `link_libunwind` flag in
the frontend driver code. This allows a project to request zig to
provide libunwind even if the default situation that causes it to be
implicitly added, is not active.
* build.zig: ask for -lunwind when building the self-hosted compiler on
Linux. Otherwise we get linker errors with unresolved symbols to
libunwind.
* for cross testing stage2 tests, we use `darling shell` command
since the path to the tested binary is relative to cwd
* for the `zig test` command, we simply use `darling` since the
path to the binary is absolute
With this change, it is now possible to use zig-bootstrap as the
initial C/C++ compiler, and then build stage2 with the resultant
stage1 without the need to link any system libs!
On CI, we have been running into OOM issues when running the test
suite on Windows for quite some time.
Unfortunately, we are very close to having the same issues on Linux
as well. Some additional comptime work immediately makes these builds
fail as well.
Add a new `test-toolchain` step, that tests everything except `std.*`
and documentation.
On CI, call `test-toolchain`, `test-std` and `docs` separately
instead of the `test` big hammer that emcompasses all of them.
Change the special case we made for Windows to the same code as other
platforms.
This is a stopgap measure that stage2 will eventually make useless.
Until then, it gives us some headroom.
Change `linux_script` by the way to only output the log of failing
steps. This shrinks the Linux CI log from a bazilion lines down to
something more humanely manageable.
* AstGen: emit decl lookup ZIR instructions rather than directly
looking up decls in AstGen. 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
* Add some more tests for the sqrt/sqrtf implementations.
The idea is to cross-check the software impl with the HW one whenever
possible.
* Fix a broken test, oops.
Previously you had to recompile if you wanted to change the log scopes
that get printed. Now, log scopes can be set at runtime, and -Dlog
controls whether all logging is available at runtime.
Purpose here is a nicer development experience. Most likely stage2
developers will always want -Dlog enabled and then pass --debug-log
scopes when debugging particular issues.
* remove the -Ddump-zir thing. that's handled through --verbose-ir
* rework Fn to have an is_inline flag without requiring any more memory
on the heap per function.
* implement a rough first version of dumping typed zir (tzir) which is
a lot more helpful for debugging than what we had before. We don't
have a way to parse it though.
* keep track of whether the inline-ness of a function changes because
if it does we have to go update callsites.
* add compile error for inline and export used together.
inline function calls and comptime function calls are implemented the
same way. A block instruction is set up to capture the result, and then
a scope is set up that has a flag for is_comptime and some state if the
scope is being inlined.
when analyzing `ret` instructions, zig looks for inlining state in the
scope, and if found, treats `ret` as a `break` instruction instead, with
the target block being the one set up at the inline callsite.
Follow-up items:
* Complete out the debug TZIR dumping code.
* Don't redundantly generate ZIR for each inline/comptime function
call. Instead we should add a new state enum tag to Fn.
* comptime and inlining branch quotas.
* Add more test cases.

restore cmake to be capable of figuring out the zig version
restore config.h and config.zig. config.h is used to detect whether we
should propagate cmake configuration information to build.zig; however
it can be overridden with -Dstatic-llvm.
fix not passing -DZIG_LINK_MODE with zig build.
when using the cmake build path, build.zig no longer tries to call
llvm-config. Instead it relies 100% on the LLVM_LIBRARIES cmake variable.
build.zig logic reworked and simplified.
