2015-09-12remove STRUCT_VALUE macroTrevor Saunders8-22/+14
This macro was converted to the TARGET_STRUCT_VALUE_RTX hook many years ago, however there are still some lingering definitions, and a use in libobjc. All the remaining definitions define the macro to 0, which libobjc treats the same as undefined, so it won't break anything else to have libobjc stop checking the macro. However it may be that this part of libobjc has been broken for a long time on targets that only define the hook, but that is a separate issue. gcc/ChangeLog: 2015-09-12 Trevor Saunders <tbsaunde+gcc@tbsaunde.org> * config/arc/arc.h: Remove define of STRUCT_VALUE. * config/lm32/lm32.h: Likewise. * config/mep/mep.h: Likewise. * config/visium/visium.h: Likewise. * system.h: Poison STRUCT_VALUE macro. libobjc/ChangeLog: 2015-09-12 Trevor Saunders <tbsaunde+gcc@tbsaunde.org> PR libobjc/24775 * sendmsg.c: Remove check of STRUCT_VALUE macro.

2015-09-10Stop reload1.c warning from breaking bootstrapRichard Sandiford2-0/+8
Some host-target combinations get bogus warnings about orig_dup being used uninitialized. I tried to coerce the current uninit pass to handle this case, but the patch I ended up with only worked by accident because of the strange way in which the pass handles limit cases. (If we have more than MAX_NUM_CHAINS chains, it silently drops the excess chains and continues regardless, so it's quite easy to come up with cases where the predicates for either the definition or the use consider an arbitrary subset of the actual conditions.) For now this patch turns -Wmaybe-uninitialized into a warning for the affacted function. It will be a warning even if someone turns off warnings on the command line, but I don't think that's important. Bootstrapped and regression-tested on x86_64-linux-gnu. Also tested with a cross-compiler to sparc-linux-gnu (which also triggered the warning for me). gcc/ * reload1.c (elimination_costs_in_insn): Locally turn -Wmaybe-uninitialized into a warning.
