Paolo Bonzini <bonzini at gnu dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bonzini at gnu dot org Known to fail| | --- Comment #8 from Paolo Bonzini <bonzini at gnu dot org> 2010-11-03 18:51:46 UTC --- flag_wrapv should not be respected by combine because PLUS/MINUS in RTL should _always_ have wrapping semantics. The right place for this optimization is in fold-const.c, especially in the current GCC world.
