* | MCP: Fixed bug with dest overlapping copy source | Tim Renouf | 2019-11-12 | 1 | -0/+27 |
In MachineCopyPropagation, when propagating the source of a copy into the operand of a later instruction, bail if a destination overlaps (partly defines) the copy source. If the instruction where the substitution is happening is also a copy, allowing the propagation confuses the tracking mechanism.
