[AMDGPU,test] Change llc -march= to -mtriple= (#75982)

2024-01-17T05:54:58+00:00

Similar to 806761a7629df268c8aed49657aeccffa6bca449.

For IR files without a target triple, -mtriple= specifies the full
target triple while -march= merely sets the architecture part of the
default target triple, leaving a target triple which may not make sense,
e.g. amdgpu-apple-darwin.

Therefore, -march= is error-prone and not recommended for tests without
a target triple. The issue has been benign as we recognize
$unknown-apple-darwin as ELF instead of rejecting it outrightly.

This patch changes AMDGPU tests to not rely on the default
OS/environment components. Tests that need fixes are not changed:

```
  LLVM :: CodeGen/AMDGPU/fabs.f64.ll
  LLVM :: CodeGen/AMDGPU/fabs.ll
  LLVM :: CodeGen/AMDGPU/floor.ll
  LLVM :: CodeGen/AMDGPU/fneg-fabs.f64.ll
  LLVM :: CodeGen/AMDGPU/fneg-fabs.ll
  LLVM :: CodeGen/AMDGPU/r600-infinite-loop-bug-while-reorganizing-vector.ll

[AMDGPU] Convert some tests to opaque pointers (NFC)

AMDGPU: Add some tests for exotic denormal mode combinations

AMDGPU: Remove denormal subtarget features

2020-04-02T21:17:12+00:00

Switch to using the denormal-fp-math/denormal-fp-math-f32 attributes.

AMDGPU: Assume f32 denormals are enabled by default

2020-04-02T21:17:12+00:00

This will likely introduce catastrophic performance regressions on
older subtargets, but should be correct. A follow up change will
remove the old fp32-denormals subtarget features, and switch to using
the new denormal-fp-math/denormal-fp-math-f32 attributes. Frontends
should be making sure to add the denormal-fp-math-f32 attribute when
appropriate to avoid performance regressions.

AMDGPU: Drop remnants of byval support for shaders

2019-07-12T20:12:17+00:00

Before 2018, mesa used to use byval interchangably with inreg, which
didn't really make sense. Fix tests still using it to avoid breaking
in a future commit.

AMDGPU: Remove llvm.AMDGPU.kill

2018-12-07T17:46:16+00:00

This is the last of the old AMDGPU intrinsics.

AMDGPU: Fix tests using old number for constant address space

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel

2017-03-21T21:39:51+00:00

Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.

Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).
