--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Doesn't reproduce on the trunk since
r11-3300-g83e037364e0d6dd74d595751e8bc8c461b4cb8fa
Adjusted testcase so that it doesn't loop forever when not miscompiled and
doesn't need -fPIC either:
struct S { unsigned short x, y; } m = { 1, 0 };
__attribute__((noipa)) void
bar ()
{
throw 1;
}
void
foo ()
{
while (1)
{
int a = m.x + 1;
int b = m.y + 1;
for (int h = 0; h < a; h++)
for (int w = 0; w < b; w++)
__builtin_printf ("w: %d, b: %d\n", w, b);
bar ();
}
}
int
main ()
{
try
{
foo ();
}
catch (int)
{
}
return 0;
}
