--- Comment #7 from Bernie Innocenti <bernie at codewiz dot org> --- > Why does this use the "f" constraint when it wants an address register? Dropping "f" doesn't make any difference, I tried that in the "call_const_plain_r()" case of my initial report: https://gcc.gnu.org/bugzilla/attachment.cgi?id=65196 I think it was there so the same macros can be used with functions taking fp args as well as integral args.
