Can we disable it for AMX type? The pointer to AMX type is meaningless and may result in bad perfomance. ================ Comment at: llvm/lib/Target/X86/X86LowerAMXType.cpp:300 + // If the dst type is <256 x i32>*, it is valid intruction. + // %0 = bitcast x86_amx* %tile to <256 x i32>* + // %1 = load <256 x i32>, <256 x i32>* %0, align 64 ---------------- I don't see any chance this happen. But we still need to handle the x86_amx* here if possible, right? Maybe better to give an assertion for now. ``` cast<PointerType>(Src->getType())->isX86_AMXTy() ``` Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D91927/new/ https://reviews.llvm.org/D91927 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
