Matt Arsenault	4eea3f3da3	AMDGPU: Implement computeKnownBitsForTargetNode for mbcnt ... llvm-svn: 318100	2017-11-13 22:55:05 +00:00
Matt Arsenault	3dbeefa978	AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel ... 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	2017-03-21 21:39:51 +00:00
Matt Arsenault	8885910f8e	AMDGPU: Remove llvm.SI.tid intrinsic ... Mesa doesn't emit this for llvm >= 3.8 anymore. llvm-svn: 273050	2016-06-17 21:18:41 +00:00
Matt Arsenault	24692118ba	AMDGPU: Avoid using 64-bit shift for i64 (shl x, 32) ... This can be done only with moves which theoretically will optimize better later. Although this transform increases the instruction count, it should be code size / cycle count neutral in the worst VALU case. It also seems to slightly improve a couple of testcases due to other DAG combines this exposes. This is probably slightly worse for the SALU case, so it might be better to handle this during moveToVALU, although then you lose some simplifications like the load width reducing in the simple testcase. llvm-svn: 242177	2015-07-14 18:20:33 +00:00
Tom Stellard	45bb48ea19	R600 -> AMDGPU rename ... llvm-svn: 239657	2015-06-13 03:28:10 +00:00
