56cee0c2cf fix: made suggested changes to add a playdate subtarget, updated help text and reduce required build flags for playdate to just the subtarget, no-movt and cortex-m7 added to default on playdate subtarget flag. 2026-07-01 21:18:28 +01:00

a3fa3476c6 feat(arm32 cdecl): Added thumb as the triple for cortex-m7. Updated the calling convention for cortex-m7 arm32 micro processors as the soft float register was being used when calling across the C ABI boundary causing guff data to be passed. 2026-06-30 20:07:36 +01:00

c3bae964d0 amd64 abi fixes regarding vectors 
- Fixes the code so SSEUp is grouped/skipped over properly (Fixes #5429)
- Fixes f16 vectors using garbage widths, because it would call
LLVMGetIntTypeWidth and an f16 is not an int so doesn't have that
function

f9b9e9e7dc some ABI fixups and improvements 
Started with trying to enable asan in the CI for MacOS, noticed it wasn't enabled on the `tests/internal`
folder, it came up with a couple of issues with the abi/OdinLLVMBuildTransmute that this also solves.

- Looking at clang output for arm64, we should be promoting `{ i64, i32 }` to `{ i64, i64 }`
- after doing the previous point, I noticed this is not handled well in OdinLLVMBuildTransmute
  which was emitting loads and stores into the space of a value that was alignment, asan does not want this,
  looking at clang output again, a memcpy is the appropriate way of handling this.
- Having done this we don't need the hacky "return is packed" set anymore in the amd64 sysv ABI anymore either

133b45d843 fix amd64 sysv abi to pass asan everywhere 
I verified the PR by running the entire test suite of Odin itself with
`-sanitize:address` and also the ols test suite (which caused unique problems
before).

A test has also been added with some problematic code, Windows seems to
have problems with asan in CI or in general so it is not ran there.

The LB_ABI_COMPUTE_RETURN_TYPES block has been removed entirely because
it was unused, I got pretty confused why it didn't effect anything at
first.

Fixes #3211

07a9969a41 darwin: arm64 abi fixes 
Since commit b4fe9677a1 some core tests
segfault during build, upon investigation it is because some arg types
were of size 0 and you can't have a 0 sized int.

It also applies the earlier fix for parameters to the return types, this
fixes #3223

Thought I would put this PR up, but I am in no way an expert in abi so
feel free to close for a better fix if there is one.

I am able to run the entire core test suite with `-sanitize:address`
with these changes.
