…hongh-131784) Use the standard `__ARM_ARCH` macro, which is supported by GCC and Clang. The branching logic for of `__ARMEL__` has been removed so if the target architecture supports v7+ instructions, a yield is emitted, otherwise a nop is emitted. This covers both big and little endian scenarios. (cherry picked from commit 03f6c8e) Co-authored-by: Vincent Fazio <vfazio@gmail.com> Signed-off-by: Vincent Fazio <vfazio@gmail.com>
