* AMDGPU: Fix capitalized register names in asm constraintsMatt Arsenault2019-06-141-1/+1
| | | | | | | This was a workaround a long time ago, but the canonical lower case names work now. llvm-svn: 363459
* [AMDGPU] Add more test cases of D59608.Michael Liao2019-04-021-0/+51
| | | | | | | | | | | | | | Summary: - Add more test cases. Reviewers: arsenm Subscribers: kzhuravl, jvesely, wdng, nhaehnle, yaxunl, dstuttard, tpr, t-tye, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D60071 llvm-svn: 357442
* [CodeGen] Handle vector UADDO, SADDO, USUBO, SSUBONikita Popov2019-02-071-1/+19
| | | | | | | | | | | | | | | This is part of https://bugs.llvm.org/show_bug.cgi?id=40442. Vector legalization is implemented for the add/sub overflow opcodes. UMULO/SMULO are also handled as far as legalization is concerned, but they don't support vector expansion yet (so no tests for them). The vector result widening implementation is suboptimal, because it could result in a legalization loop. Differential Revision: https://reviews.llvm.org/D57639 llvm-svn: 353464
* AMDGPU: Use gfx9 carry-less add/sub instructionsMatt Arsenault2017-11-301-8/+30

* AMDGPU: Allow SIShrinkInstructions to work in non-SSAMatt Arsenault2017-07-101-1/+1
| | | | | | | | 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: Add macro fusion schedule DAG mutationMatt Arsenault2017-07-061-2/+2
| | | | | | Try to increase opportunities to shrink vcc uses. llvm-svn: 307313
* [AMDGPU] Switch scalarize global loads ON by defaultAlexander Timofeev2017-07-041-3/+3

* Revert r307026, "[AMDGPU] Switch scalarize global loads ON by default"NAKAMURA Takumi2017-07-041-3/+3
| | | | | | | | | It broke a testcase. Failing Tests (1): LLVM :: CodeGen/AMDGPU/alignbit-pat.ll llvm-svn: 307054

* AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernelMatt Arsenault2017-03-211-7/+7
| | | | | | | | | | | | 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: Make i32 uaddo/usubo legalMatt Arsenault2017-01-301-27/+87
