AMDGPU: Replace undef global initializers in tests with poison (#131051)

AMDGPU: Replace ptr addrspace(3) undef in tests with poison (#131049)

AMDGPU: Replace ptr addrspace(1) undefs with poison (#130900)

2025-03-13T01:25:02+00:00

Many tests use store to undef as a placeholder use, so just replace
all of these with poison.

StructurizeCFG: Use poison instead of undef (#130459)

2025-03-10T15:29:15+00:00

There are a surprising number of codegen changes from this.

DAG: Use phi to create vregs instead of the constant input (#129464)

2025-03-04T07:44:54+00:00

For most targets, the register class comes from the type so this
makes no difference. For AMDGPU, the selected register class depends
on the divergence of the value. For a constant phi input, this will
always be false. The heuristic for whether to treat the value as
a scalar or vector constant based on the uses would then incorrectly
think this is a scalar use, when really the phi is a copy from S to V.

This avoids an intermediate s_mov_b32 plus a copy in some cases. These
would often, but not always, fold out in mi passes.

This only adjusts the constant input case. It may make sense to do
this for the non-constant case as well.

Reapply "[AMDGPU] Still set up the two SGPRs for queue ptr even it is COV5 (#112403)"

2024-11-09T01:21:16+00:00

This reverts commit ca33649abe5fad93c57afef54e43ed9b3249cd86.

Revert "[AMDGPU] Still set up the two SGPRs for queue ptr even it is COV5 (#112403)"

2024-11-08T21:36:35+00:00

This reverts commit e215a1e27d84adad2635a52393621eb4fa439dc9 as it broke both
hip and openmp buildbots.

Reapply "AMDGPU: Move attributor into optimization pipeline (#83131)" and follow up commit "clang/AMDGPU: Defeat attribute optimization in attribute test" (#98851)

2024-07-15T07:51:44+00:00

This reverts commit adaff46d087799072438dd744b038e6fd50a2d78.

Drop the -O3 checks from default-attributes.hip. I don't know why they
are different on some bots but reverting this is far too disruptive.

78bc1b64a6dc3fb6191355a5e1b502be8b3668e7.

The test CodeGenHIP/default-attributes.hip is failing on multiple bots
even after the attempted fix including the following:

These bots have been broken for a day, so reverting to get everything
back to green.
