* AMDGPU: Allow SIShrinkInstructions to work in non-SSAMatt Arsenault2017-07-101-3/+3
| | | | | | | | 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: Remove unnecessary ands when f16 is legalMatt Arsenault2017-03-311-1/+54
| | | | | | | | | | Add a new node to act as a fancy bitcast from f16 operations to i32 that implicitly zero the high 16-bits of the result. Alternatively could try making v2f16 legal and canonicalizing on build_vectors. llvm-svn: 299246
* 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: Fix unnecessary ands when packing f16 vectorsMatt Arsenault2017-03-151-8/+6
| | | | | | | | | computeKnownBits didn't handle fp_to_fp16 to report the high bits as 0. ARM maps the generic node to an instruction that does not modify the high bits of the register, so introduce a target node where the high bits are known 0. llvm-svn: 297873
* AMDGPU: Support v2i16/v2f16 packed operationsMatt Arsenault2017-02-271-8/+23
| | | | llvm-svn: 296396
* AMDGPU: Use source modifiers with f16->f32 conversionsMatt Arsenault2017-02-021-4/+57
| | | | | | | | | | | The operand types were defined to fit the fp16_to_fp node, which has the half as an integer type. v_cvt_f32_f16 does support source modifiers, so change this to have an FP type and modifiers. For targets without legal f16, this requires recognizing the bit operations and trying to produce them. llvm-svn: 293857
* Enable FeatureFlatForGlobal on Volcanic IslandsMatt Arsenault2017-01-241-1/+1
| | | | | | | | | | | This switches to the workaround that HSA defaults to for the mesa path. This should be applied to the 4.0 branch. Patch by Vedran Miletić <vedran@miletic.net> llvm-svn: 292982
