ZarkoCA added inline comments.
================ Comment at: clang/lib/CodeGen/TargetInfo.cpp:4257 + // 64-bit only registers: + // 114: tfhar + // 115: tfiar ---------------- From what I've seen, the tfhar, tfiar and texasr are used by the Power8 CPU, which means that there is potential for them to be used on 64BIT AIX. I don't have access to a Power8 AIX machine to test and confirm this however. If no one else can confirm, maybe it's good to leave a TODO here to check? ================ Comment at: clang/lib/Driver/ToolChains/Clang.cpp:4541 options::OPT_msvr4_struct_return)) { - if (TC.getArch() != llvm::Triple::ppc) { + if (TC.getArch() != llvm::Triple::ppc || TC.getTriple().isOSAIX()) { D.Diag(diag::err_drv_unsupported_opt_for_target) ---------------- -maix-struct-return behaves as expected on AIX (ie. it has no change from default behaviour) but I agree, to me it makes disable both if we are not sure about one of them. However, I think it would be good to add a TODO to enable this once it's verified on AIX. ================ Comment at: clang/test/CodeGen/ppc32-and-aix-struct-return.c:55 +// CHECK-AIX-LABEL: define void @ret0(%struct.Zero* noalias sret {{[^,]*}}) +// CHECK-SVR4-LABEL: define void @ret0() +Zero ret0(void) { return (Zero){}; } ---------------- sorry, is it possible to lineup the `define ..` with the line below, for the entire testcase?
