◆ getIntImmCost() [1/4]

int AArch64TTIImpl::getIntImmCost ( int64_t  Val)

Calculate the cost of materializing a 64-bit value.

This helper method might only calculate a fraction of a larger immediate. Therefore it is valid to return a cost of ZERO.

See if I should be considered for address type promotion.

We check if I is a sext with right type and used in memory accesses. If it used in a "complex" getelementptr, we allow it to be promoted without finding other sext instructions that sign extended the same initial value. A getelementptr is considered as "complex" if it has more than 2 operands.
