Within the current infrastructure, I think that we need to alter the Clang PowerPC toolchain code (Clang::AddPPCTargetArgs in Tools.cpp) to do something like this: if (Args.hasFlag(options::OPT_fno_altivec, options::OPT_faltivec, true)) { CmdArgs.push_back("-backend-option"); CmdArgs.push_back("-mattr=-altivec"); } Why this not done currently I don't know. -Hal > > Thanks!
