FWIW I agree with Vlad and Paolo Bonzini. It seems as if 4.2 was branched with critical flaws (it happens, no biggie). In addition to the alias issues, and the resulting SPEC issues, and the compilation slowdown issues vis-a-vis 4.1 and current mainline.... then seeing this kind of commentary in a patch: http://gcc.gnu.org/ml/gcc-patches/2007-02/msg01628.html Doesn't give me great confidence in the quality or long-term maintainability of gcc-4_2-branch. In addition, it seems as if pre-df may be a better starting point for the middle/back end people (but I am not a good judge of this.) I'd rather we suck it up and re-branch rather than fjord though unknown depths with the current issues. -benjamin Subject: --text follows this line--
