This conflict is with many optimizations incl. copy prop, coalescing, hoisting etc. Each could increase register pressure and with similar impact. Attempts to control the register pressure locally (within an optimization pass) tend to get hard to tune and maintain. Would it be a better way to describe eg in metadata how to undo an optimization? Optimizations that attempt to reduce pressure like
