* [AMDGPU] Fix test checksJay Foad2019-10-071-2/+4
| | | | | | | | The GFX10-DENORM-STRICT checks were only passing by accident. Fix them to make the test more robust in the face of scheduling or register allocation changes. llvm-svn: 373893
* [AMDGPU] gfx1010: use fmac instructionsStanislav Mekhanoshin2019-05-041-81/+185
| | | | | | Differential Revision: https://reviews.llvm.org/D61527 llvm-svn: 359959
* [AMDGPU] Removed redundant run lines for fmuladd.f16 test. NFC.Stanislav Mekhanoshin2018-02-201-4/+0

* AMDGPU: Fix -enable-var-scope violationsMatt Arsenault2017-11-121-9/+9

* DAG: Fold fma (fneg x), K, y -> fma x, -K, yMatt Arsenault2017-10-271-2/+2
| | | | llvm-svn: 316753
* AMDGPU: Allow SIShrinkInstructions to work in non-SSAMatt Arsenault2017-07-101-14/+14
| | | | | | | | Immediates can be folded as long as the immediate is a vreg. Also undo commuting instructions if it didn't fold an immediate. llvm-svn: 307575
* AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernelMatt Arsenault2017-03-211-17/+17
| | | | | | | | | | | | 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). llvm-svn: 298444
* AMDGPU: Combine fp16/fp64 subtarget featuresMatt Arsenault2017-01-231-9/+9
| | | | | | | The same control register controls both, and are set to the same defaults. Keep the old names around as aliases. llvm-svn: 292837
* AMDGPU: Swap order of operands in fadd/fsub combineMatt Arsenault2016-12-221-2/+2
| | | | | | | FMA is canonicalized to constant in the middle operand. Do the same so fmad matches and avoid an extra combine step. llvm-svn: 290313
* AMDGPU: Form more FMAs if fusion is allowedMatt Arsenault2016-12-221-0/+467
Extend the existing fadd/fsub->fmad combines to produce FMA if allowed. llvm-svn: 290311
