[ARM] Use __ARM_ARCH and __ARM_FEATURE_LDREX instead of __ARM_ARCH__
2018-06-21 Christophe Lyon <christophe.lyon@linaro.org>
libatomic/
* config/arm/arm-config.h (__ARM_ARCH__): Remove definitions, use
__ARM_ARCH instead. Use __ARM_FEATURE_LDREX to define HAVE_STREX
and HAVE_STREXBHD
libgcc/
* config/arm/lib1funcs.S (__ARM_ARCH__): Remove definitions, use
__ARM_ARCH and __ARM_FEATURE_CLZ instead.
(HAVE_ARM_CLZ): Remove definition, use __ARM_FEATURE_CLZ instead.
* config/arm/ieee754-df.S: Use __ARM_FEATURE_CLZ instead of
__ARM_ARCH__.
* config/arm/ieee754-sf.S: Likewise.
* config/arm/libunwind.S: Use __ARM_ARCH instead of __ARM_ARCH__.
