From: Andrew MacLeod Date: Thu, 25 Jun 2015 16:51:35 +0000 (+0000) Subject: function.h (struct incoming_args): Move struct. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=16a16ec7db0a5c626567b57ba49e09c4a5cccb76;p=gcc.git function.h (struct incoming_args): Move struct. 2015-06-25 Andrew MacLeod * function.h (struct incoming_args): Move struct. (pass_by_reference, reference_callee_copied): Remove prototypes. * emit-rtl.h (struct incoming_args): Relocate struct here. * calls.h (pass_by_reference, reference_callee_copied): Relocate prototypes here. * function.c (pass_by_reference, reference_callee_copied): Move. * calls.c (pass_by_reference, reference_callee_copied): Relocate here. * cfgloop.h: Don't include tm.h or hard-reg-set.h. * ipa-chkp.c: Include calls.h. * ada/gcc-interface/misc.c: Include calls.h not function.h. * c-family/cilk.c: Move calls.h after tm.h in the include chain.
