From: Andrew Pinski <apin...@marvell.com> To able to move PHI-OPT's abs_replacement to match.pd, a bunch of support needed to be added to PHI-OPT. This is a set of 7 patches which allows us to remove abs_replacement and even does one set further and does a few extra transformations that abs_replacement did not do (just because of the moving from fold to match).
Andrew Pinski (7): Expand the comparison argument of fold_cond_expr_with_comparison Reset the range info on the moved instruction in PHIOPT Duplicate the range information of the phi onto the new ssa_name Allow match-and-simplified phiopt to run in early phiopt Try inverted comparison for match_simplify in phiopt Lower for loops before lowering cond in genmatch Port most of the A CMP 0 ?
