* [AMDGPU] Improve code size cost modelDaniil Fukalov2019-10-171-4/+6
| | | | | | | | | | | | | | | | | | | Summary: Added estimation for zero size insertelement, extractelement and llvm.fabs operators. Updated inline/unroll parameters default values.

* AMDGPU: Make some packed shuffles freeMatt Arsenault2017-05-101-15/+28
| | | | | | | VOP3P instructions can encode access to either half of the register. llvm-svn: 302730
* AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernelMatt Arsenault2017-03-211-4/+4
| | | | | | | | | | | | 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

We don't want to have a cost to scalarizing operations. llvm-svn: 264364
