isFullSizeType()

bool isFullSizeType ( CIRGenModule & cgm, mlir::Type ty, uint64_t expectedSize )

static

Does a store of the given IR type modify the full expected width?

shouldCastToInt()

bool shouldCastToInt ( mlir::Type valueTy, bool cmpxchg )

static

Return true if.

Parameters

valueTy	is a type that should be casted to integer around the atomic memory operation. If
cmpxchg	is true, then the cast of a floating point type is made as that instruction can not have floating point operands. TODO: Allow compare-and-exchange and FP - see comment in CIRGenAtomicExpandPass.cpp.
