* [AMDGPU] Eliminate no effect instructions before s_endpgmStanislav Mekhanoshin2017-08-161-1/+3

* AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernelMatt Arsenault2017-03-211-1/+1
| | | | | | | | | | | | 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: Implement read_register and write_register intrinsicsMatt Arsenault2016-01-261-0/+22
Some of the special intrinsics now that now correspond to a instruction also have special setting of some registers, e.g. llvm.SI.sendmsg sets m0 as well as use s_sendmsg. Using these explicit register intrinsics may be a better option. Reading the exec mask and others may be useful for debugging. For this I'm not sure this is entirely correct because we would want this to be convergent, although it's possible this is already treated sufficently conservatively. llvm-svn: 258785
