--- Comment #19 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Aldy Hernandez from comment #16) > It seems tree-ssa-reassoc.c avoids reassociating most non-bit expressions by > design (because of signed overflows): [...] > So instead of whacking tree-ssa-reassoc.c to handle POINTER_PLUS_EXPR and > PLUS_EXPR, etc, There have been suggestions that we should do reassoc after some kind of lowering, where all integer operations wrap, maybe pointer operations are replaced with integer operations, etc.
