--- Comment #32 from Alan Modra <amodra at gcc dot gnu.org> --- Author: amodra Date: Mon Oct 19 23:50:30 2015 New Revision: 229009 URL: https://gcc.gnu.org/viewcvs?rev=229009&root=gcc&view=rev Log: PR66870 PowerPC64 Enable gold linker with split stack A powerpc-linux/powerpc64-linux biarch compiler can default to either -m32 or -m64, and we need to notice both -m32 and -m64 on the gccgo command line. It's also possible to build a -m64 only compiler, so in that case we can define TARGET_CAN_SPLIT_STACK. gcc/ PR go/66870 * config/rs6000/sysv4.h (TARGET_CAN_SPLIT_STACK_64BIT): Don't define. * config/rs6000/linux64.h (TARGET_CAN_SPLIT_STACK): Define. (TARGET_CAN_SPLIT_STACK_64BIT): Define. gcc/go/ PR go/66870 * gospec.c (saw_opt_m32): Rename to.. (is_m64): ..this, initialised by TARGET_CAN_SPLIT_STACK_64BIT. Update uses. (lang_specific_driver): Set is_m64 if OPT_m64, clear if OPT_m32.
