[PATCH] D29116: Regression in 4.0-rc: SPARC: allow %f-registers for inline-assembly

[James Y Knight via Phabricator via llvm-commits]

jyknight added a comment.

Is it desirable for the supported register constraints to have the same meaning as in GCC, and this is not: GCC defines 'f' as the lower fp regs, and 'e' as all of the fp regs. (Those are only actually different for sparcv9, of course.)

Also, you'll need to the inlineasm docs in the LangRef to add the new constraint.
