Reverting that patch Jan said that his patch did not change the results of the test, so presumably something else changed somewhere. Reverting that patch removes most of the warnings from c90-const-expr-3.c and c99-const-expr-3.c, although we still get warnings for +0.0, 0.0+0.0, and (double)0.0. -- What |Removed |Added ---------------------------------------------------------------------------- CC| |ian at airs dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=5675 ^ permalink raw reply [flat|nested] 8+ messages in thread
