[PATCH] D10414: Attach function attribute "arm-restrict-it" instead of passing arm-restrict-it as a backend-option

Hi Jim,

In an ideal world, yes. However there's no guarantee that all ARM implementors will (a) be able to commit to LLVM or (b) use ToT. Perhaps they're building a project that uses clang, or a specific version of clang, and this tuning option makes things go faster on their architecture.

I'm not arguing about the defaults, just about the breakage of -mno-restrict-it.

Cheers,

James
