Struct AtomicCmpxchgOp 

pub struct AtomicCmpxchgOp { /* private fields */ }

Equivalent to LLVM’s cmpxchg: atomically compares the value at a pointer with cmp and, if equal, stores new. Returns a { value, i1 } pair of the loaded value and whether the swap succeeded.

Operands

operand	description
ptr	PointerType
cmp	expected value
new	value to store on success

Result(s):

result	description
res	{ value, i1 } (loaded value, success flag)

Attribute(s):

Note: Only attributes defined directly as part of this operation are listed here. There may be others, not listed here, defined by interface implementations.
