Not sure if I understand your concern. We allocate SGPRs in a separate pass before VGPRs. So, we have the whole amount of VGPRs available on a given target to spill SGPRs. I hardly can imagine a kernel that requires 256x32 SGPRs. https://github.com/llvm/llvm-project/pull/108596 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
