Hi, we just inherited this commit at Cray when we did our latest upstream merge and there are a few problems with it that I'd like to point out. Sorry that I was not part of the initial discussion here, but I didn't know that this work was being done and I had already done it for x86 in our downstream compiler a while ago.
1. This patch adds the -m options to f_Group, which is weird. They should be in m_Group since they are target-specific. I actually implemented them as part of a subgroup of m_Group so that I can take the last option from that group that appears on the command line.
2. This patch lacks the GNU -mlong-double-80 option for x86.
3. Instead of tracking the size in clang/Basic/LangOptions.def, I track it in clang/Basic/TargetOptions.h. This is a target-specific thing afterall.
We're trying to resolve merge conflicts with this change and might be able to submit a patch to help reduce our differences. Would that be of interest?
