AMDGPU: Make frame register caller preserved Using SplitCSR for the frame register was very broken. Often the copies in the prolog and epilog were optimized out, in addition to them being inserted after the true prolog where the FP was clobbered. I have a hacky solution which works that continues to use split CSR, but for now this is simpler and will get to working programs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@313274 91177308-0d34-0410-b5e6-96231b3b80d8
