AMDGPU: Remove some -verify-machineinstrs from tests (#117736)

2024-11-26T17:59:15+00:00

We should leave these for EXPENSIVE_CHECKS builds. Some of these
were near the top of slowest tests.

APFloat: Fix signed zero handling in minnum/maxnum (#83376)

2024-02-29T11:21:33+00:00

Follow the 2019 rules and order -0 as less than +0 and +0 as greater
than -0. As currently defined this isn't required for the intrinsics,
but is a better QoI.

This will avoid the workaround in libc added by #83158

[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:

```

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

2022-12-19T11:41:13+00:00

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.

DAG: Change behavior of fminnum/fmaxnum nodes

2018-10-22T16:27:27+00:00

Introduce new versions that follow the IEEE semantics
to help with legalization that may need quieted inputs.

There are some regressions from inserting unnecessary
canonicalizes when these are matched from fast math
fcmp + select which should be fixed in a future commit.

AMDGPU: Split amdgcn/r600 fminnum/fmaxnum tests

2018-07-31T20:38:42+00:00

R600 breaks on too many things to usefully test changes
with ieee_mode on vs. off.

AMDGPU: Stop wasting argument registers with v3i32/v3f32

2018-07-28T14:11:34+00:00

SelectionDAGBuilder widens v3i32/v3f32 arguments to
to v4i32/v4f32 which consume an additional register.
In addition to wasting argument space, this produces extra
instructions since now it appears the 4th vector component has
a meaningful value to most combines.

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).
