◆ changeElementSizeTo()

LegalizeMutation llvm::LegalizeMutations::changeElementSizeTo ( unsigned  TypeIdx,
unsigned  FromTypeIdx 
)

Change the scalar size or element size to have the same scalar size as type index FromIndex.

Unlike changeElementTo, this discards pointer types and only changes the size.
