Closes #14715
Closes #14783
|
|
At least lldb misbehaves with all these same-named unions, so just
generate a unique name.
|
|
Replace `ArrayList` with `ArrayHashMap` since we want to be able to
remove by element.
|
|
Many `Type`s can correspond to the same `CType`, so this reduces the
number of used locals by 27760 when compiling only-c.
Also, disabled some tests that were only passing by accident and
shouldn't really be considered working.
|
|
Turns out f(...) will be supported one day.
|
|
|
|
It should be Sema's job to check this anyway.

After this, the last MSVC warnings are in behavior/bugs/529.zig:
behavior.c(37971): warning C4133: 'function': incompatible types - from 'A__8479 *' to 'A__8474 *'
behavior.c(37974): warning C4133: 'function': incompatible types - from 'A__8480 *' to 'A__8474 *'

|
* Support always_tail and never_tail/never_inline with a comptime callee using clang
* Support never_inline using gcc
* Support never_inline using msvc
Unfortunately, can't enable behavior tests because of the conditional support.
|
|
Removed some backend test skip checks for things disabled in std.
|
|
|
|
* Implement @fieldParentPtr on a union
* Refactor field access to ensure that it is handled consistently
* Remove `renderTypecast` as it is now behaves the same as `renderType`

Adds a new mechanism for `@tagName` function generation that doesn't
piggyback on the removed typedef system.
|
|
This requires manual defines before C99 which may not have stdint.h.
Also have update-zig1 leave a copy of lib/zig.h in stage1/zig.h, which
allows lib/zig.h to be updated without needing to update zig1.wasm.
Note that since the object already existed with the exact same contents,
this completely avoids repo bloat due to zig.h changes.

Same as 0577069af5f5deb859762725736537d60c324453 for extern functions.

link: move ownership of linker atom from frontend to the linkers
|
|
|
|
This API only depends on std.Target and is extremely useful in build
scripts when populating configure files.
|
|
- cbe: Implement linksection support, to support TLS when not linking libc
- cbe: Support under-aligned variables / struct fields
- cbe: Support packed structs (in the C definition of packed)
- windows: Fix regression with x86 _tls_array
- compiler_rt: Add 128-bit atomics to compiler_rt
- tests: Re-enable threadlocal tests on cbe+windows, and llvm+x86
- tests: Re-enable f80 tests that now pass
- ci: change windows ci to run the CBE behaviour tests with -lc, to match how the compiler is bootstrapped
- update zig1.wasm

|
|
- Emit calling convention
- Fix .Naked handling for msvc
- Add teb helper for x86
- Fix 128-bit shl implementation when rhs is >= 64
- Add 128-bit shl tests
|

|
|
llvm: implement Stdcall calling convention
|
|
|
|
- add c_abi tests for .Stdcall
- enable (x86|x86_64)-windows-gnu in the c_abi tests

Closes #14261

This is a simple starting version of the optimization described in #168
where the fields are just sorted by order of descending alignment.

@bitCast from integer NaN representation to float NaN resulted in
changed bits in float. This only happened with signaled NaN.
- added test for signaled NaN
- added tests for quiet NaN (for completeness)

- Add cpuid / getXCR0 functions for the cbe to use instead of asm blocks
- Don't cast between 128 bit types during truncation
- Fixup truncation to use functions for shifts / adds
- Fixup float casts for undefined values
- Add test for 128 bit integer truncation
|
|
- add zig_mul_i128
- render slice structs in static initializers without casts / c99 style init
- add negative numbers and u128 to 128-bit multiply test
