- Delete all position markers from assembler code before optimization. Markers of this kind are not used by optimizer and are expected to be ignored, but ignoring them requires numerous checks in all target-specific optimizers and currently isn't done correctly. In turn, failure to ignore markers prevents optimization of procedure prologues and epilogues.
