; This file checks that atomic (non-seq_cst) stores of immediate values are
; done in one mov instruction and not 2. 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.
