				/*
				* The following x-macros control the generation of ASAN interceptor functions
				* in subr_asan.c.
				*
				* By default, the MI code(atomic_san.h) assumes that the underlying
				* architecture supports all atomic operations across all widths. If a specific
				* MD architecture(machine/atomic.h) lacks support for certain atomic widths
				* (e.g., 8-bit or 16-bit), it should override these ARCH_SUPPORT_* macros in
				* its machine/atomic.h and #undef the corresponding atomic_* macros to prevent
				* the generation of unsupported interceptors.
