2017-12-20[aarch64][libstdc++] Use __ARM_BIG_ENDIAN instead of __AARCH64EB__ in ↵Kyrylo Tkachov2-1/+6
opt_random.h As has been spotted at https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01289.html we check the __AARCH64EB__ macro for aarch64 big-endian detection in config/cpu/aarch64/opt/ext/opt_random.h. That works just fine with GCC but the standardised ACLE[1] macro for that purpose is __ARM_BIG_ENDIAN so there is a possibility that non-GCC compilers that include this header are not aware of this predefine. So this patch changes the use of __AARCH64EB__ to the more portable __ARM_BIG_ENDIAN. Tested on aarch64-none-elf and aarch64_be-none-elf. Preapproved by Jeff at https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01326.html * config/cpu/aarch64/opt/ext/opt_random.h (__VEXT): Check __ARM_BIG_ENDIAN instead of __AARCH64EB__. From-SVN: r255857
