search for: __dsb

Hi all, I'm currently working on implementing ACLE extensions for ARM. There are some memory barrier intrinsics, i.e.__dsb and __isb that require the compiler not to reorder instructions around their corresponding built-in intrinsics(__builtin_arm_dsb, __builtin_arm_isb), including non-memory-access instructions.[1] This is currently not possible. It is sometimes useful to prevent the compiler from reordering memory-a...
