Paolo Bonzini <bonzini at gnu dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bonzini at gnu dot org --- Comment #15 from Paolo Bonzini <bonzini at gnu dot org> --- fold-mem-offsets seems to be a lot similar to fwprop... perhaps it could use the multiple definitions DF problem that was introduced for fwprop in 2009?... It's still there though it's unused, and it's a lot easier to retrofit than RTL-SSA that fwprop now uses.
