◆ handleMemIntrinsicPtrUse()

static bool handleMemIntrinsicPtrUse ( MemIntrinsic MI,
Value OldV,
Value NewV 
)
static

Update memory intrinsic uses that require more complex processing than simple memory instructions.

These require re-mangling and may have multiple pointer operands.

◆ isSimplePointerUseValidToReplace()

static bool isSimplePointerUseValidToReplace ( const TargetTransformInfo TTI,

)
static

returns true if U is the pointer operand of a memory instruction with a single pointer operand that can have its address space changed by simply mutating the use to a new value.

If the memory instruction is volatile, return true only if the target allows the memory instruction to be volatile in the new address space.
