Member Data Documentation

ChangesValue

bool llvm::SpillPlacement::BlockConstraint::ChangesValue

True when this block changes the value of the live range.

This means the block has a non-PHI def. When this is false, a live-in value on the stack can be live-out on the stack without inserting a spill.
