demo source code
Actually, it seems -fregmove related (-fno-regmove fixes it). Apparently -fregmove decides to merge a /u register with a changeable one, debugging. Ouch, forgot to update status here: I've fixed this with http://gcc.gnu.org/ml/gcc-patches/2001-05/msg00581.html and it will be included in gcc-2.96-86. |
