Thanks. Unfortunately that still doesn't answer the question. It says: > The -mcpu and -march options are very similar in > clang.

Still '-march=pentium-m' (which is available for gcc) is not recognized by clang. So I am afraid I don't know how to use this info practically. I have also seen: https://clang.llvm.org/docs/CrossCompilation.html#general-cross-compilation-options-in-clang but it is still not clear what hides behind those "etc". It doesn't even mention -march and there no clear list of what one can use for -mcpu. This is very confusing. -- George _______________________________________________ cfe-users mailing list cfe-users@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
