It might not block the compilation process, but it might break the linking process (build attributes, libraries), or change code generation, with regards to vectorization and optimizations. I agree this is not critical, but it's the kind of bug that is hard to find (as opposed to a compilation error), and the kind of warnings that people tend not to look at. I have no more arguments against the removal, and I don't feel too bad about it, but was just raising the issue. If people think it's for the best, I'll go with it. > Gcc can accept "-mcpu" with modifiers. Hum... ok, I had no idea, and from their docs, it's not clear also. In that case, fine by me. Thanks for threading this awkward minefield! I think Tim and others more involved in the AArch64 port should have a final look, but from what you discussed, I have no more objections. cheers, --renato _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
