* stage2: array mul support more types of operands
* stage2: array cat support more types of operands
* print_zir: print array_init
* stage2: implement Sema for array_init
There was duplicated logic for whether to include compiler_rt in the
linker line both in the frontend and in the linker backends. Now the
logic is only in the frontend; the linker puts it on the linker line if
the frontend provides it.
Fixes the CI failures.
This prevents a compiler_rt built with stage2 (which is intentionally
different than when built with stage1) from being used for stage1 and
vice versa.
Fixes the regression from the previous commit.
* AstGen: fix emitting `store_to_inferred_ptr` when it should be emitting
`store` for a variable that has an explicit alignment.
* Compilation: fix a couple memory leaks
* Sema: implement support for locals that have specified alignment.
* Sema: implement `@intCast` when it needs to emit an AIR instruction.
* Sema: implement `@alignOf`
* Implement debug printing for extended alloc ZIR instructions.
Also improve the LLVM backend to support lowering bigints to LLVM
values.
Moves over a bunch of math.zig test cases to the "passing for stage2"
section.
* `@as` and `@bitCast` no longer unconditionally return `true` from
this function; they forward the question to their sub-expression.
* fix `@splat` incorrectly being marked as needing a memory location
(this function returns a SIMD vector; it definitely does not want a
memory location).
Makes AstGen generate slightly nicer ZIR, which in turn generates
slightly nicer AIR, generating slightly nicer machine code in debug
builds.
It also means I can procrastinate implementing the bitcast_result_ptr
ZIR instruction semantic analysis :^)
* Remove the builtins `@addWithSaturation`, `@subWithSaturation`,
`@mulWithSaturation`, and `@shlWithSaturation` now that we have
first-class syntax for saturating arithmetic.
* langref: Clarify the behavior of `@shlExact`.
* Ast: rename `bit_shift_left` to `shl` and `bit_shift_right` to `shr`
for consistency.
* Air: rename to include underscore separator with consistency with
the rest of the ops.
* Air: add shl_exact instruction
* Use non-extended tags for saturating arithmetic, to keep it
simple so that all the arithmetic operations can be done the same
way.
- Sema: unify analyzeArithmetic with analyzeSatArithmetic
- implement comptime `+|`, `-|`, and `*|`
- allow float operands to saturating arithmetic
* `<<|` allows any integer type for the RHS.
* C backend: fix rebase conflicts
* LLVM backend: reduce the amount of branching for arithmetic ops
* zig.h: fix magic number not matching actual size of C integer types
- modify AstGen binOpExt()/assignBinOpExt() to accept generic extended payload T
- rework Sema zirSatArithmetic() to use existing sema.analyzeArithmetic() by adding an `opt_extended` parameter.
- add airSatOp() to codegen/c.zig
- add saturating functions to src/link/C/zig.h
- adds initial support for the operators +|, -|, *|, <<|, +|=, -|=, *|=, <<|=
- uses operators in addition to builtins in behavior test
- adds binOpExt() and assignBinOpExt() to AstGen.zig. these need to be audited
* AIR: add `mod` instruction for modulus division
- Implement for LLVM backend
* Sema: implement `@mod`, `@rem`, and `%`.
* Sema: fix comptime switch evaluation
* Sema: implement comptime shift left
* Sema: fix the logic inside analyzeArithmetic to handle all the
nuances between the different mathematical operations.
- Implement comptime wrapping operations
* Merge call zir instructions to make space for field_call
* Fix bug with comptime known anytype args
* Delete the param_type zir instruction
* Move some passing tests to stage 2
* Implement a.b() function calls
* Add field_call_bind support for call and field builtins
* AIR: add `get_union_tag` instruction
- implement in LLVM backend
* Sema: implement == and != for union and enum literal
- Also implement coercion from union to its own tag type
* Value: implement hashing for union values
The motivating example is this snippet:
comptime assert(@typeInfo(T) == .Float);
This was the next blocker for stage2 building compiler-rt.
Now it is switch at compile-time on an integer.
* AIR instructions struct_field_ptr and related functions now are also
emitted by the frontend for unions. Backends must inspect the type
of the pointer operand to lower the instructions correctly.
- These will be renamed to `agg_field_ptr` (short for "aggregate") in
the future.
* Introduce the new `set_union_tag` AIR instruction.
* Introduce `Module.EnumNumbered` and associated `Type` methods. This
is for enums which have no decls, but do have the possibility of
overriding the integer tag type and tag values.
* Sema: Implement support for union tag types in both the
auto-generated and explicitly-provided cases, as well as explicitly
provided enum tag values in union declarations.
* LLVM backend: implement lowering union types, union field pointer
instructions, and the new `set_union_tag` instruction.
docgen HTML escapes characters inside of `syntax_block`s. This commit replaces the escaped
greater than with the `>` character. No other occurrences were found.
Fixes#9840
On certain systems (Solaris), resolving the scope id from an interface
name can only be done on AF_INET-domain sockets. While we're here,
simplify the test while we're here, since there's only one address.
Also note that the loopback interface name is not stable across OSs.
BSDs and Solaris use `lo0` whilst Linux uses `l0`.
