R600/SI: Fix tests with triples in them Only set the triple from the command line options. Some of these were still testing SI features and using the old r600-- triple. llvm-svn: 238958

LiveRangeEdit: Fix liveranges not shrinking on subrange kill. If a dead instruction we may not only have a last-use in the main live range but also in a subregister range if subregisters are tracked. We need to partially rebuild live ranges in both cases. The testcase only broke when subregister liveness was enabled. I commited it in the current form because there is currently no flag to enable/disable subregister liveness. This fixes PR23720. llvm-svn: 238785

R600: Re-enable sub-reg liveness The bug in the R600 backend that this uncovered has been fixed. llvm-svn: 238999

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
