For what it's worth, there is at least _another_ regression introduced
by the -4 or -5 revision in -O0, that I've not been able to track down
yet. I mean that when I remove all my uses of __builtin_expect in the
code that lead me to find out about this bug, I still have (at least)
another issue tha
Package: gcc-4.4
Version: 4.4.3-4
Severity: grave
Since gcc-4.4 version 4.4.3-4 (and yes -5 is still affected), gcc miscompiles
__builtin_expect when no optimization is set (at least).
Test case:
int foo(int t) {
if (__builtin_expect(t & 0x100, 0))
return 0;
retur
2 matches
