------- Comment #11 from matz at gcc dot gnu dot org 2007-10-31 23:12 ------- Your threading testcase also seems to work with my patch. It doesn't fail really reliably for me with the other compilers, so I'm not 100% certain, can you check? Patch at http://gcc.gnu.org/ml/gcc-patches/2007-10/msg01898.html (note that I only changed the tree-ssa side of things, if the RTL if-cvt did the wrong thing on your testcase it would still be broken).
