More precisely, it makes sure that the ; immediate is not first copied uselessly into a register. ; Similarily, it checks that a binary operation of an immediate with an atomic ; variable that is stored back in that variable is done as a single instruction. ; For example: x.store(42 + x.load(memory_order_acquire), memory_order_release) ; should be just an add instruction, instead of loading x into a register, doing ; an add and storing the result back. ; The binary operations supported are currently add, and, or, xor. ; sub is not supported because they are translated by an addition of the ; negated immediate. ; ; We also check the same patterns: ; - For inc/dec. ; - For register instead of immediate operands. ; - For floating point operations. ; seq_cst stores are left as (lock) xchgl, but we try to check every other ; attribute at least once. ; Please note that these operations do not require the lock prefix: only ; sequentially consistent stores require this kind of protection on X86. ; And even for seq_cst operations, llvm uses the xchg instruction which has ; an implicit lock prefix, so making it explicit is not required. define void @store_atomic_imm_8(i8* %p) { ; X64-LABEL: store_atomic_imm_8: ;
