* 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.
