AMDGPU: Preserve vcc undef flags when inverting branch If the branch was on a read-undef of vcc, passes that used analyzeBranch to invert the branch condition wouldn't preserve the undef flag resulting in a verifier error. Fixes verifier failures in a future commit. Also fix verifier error when inserting copy for vccz corruption bug. llvm-svn: 286133

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

Followup on Proposal to move MIR physical register namespace to '$' sigil. Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922
