this is small testcase for original bug (ICE in postreload.c),
it fails in 3.3 and 3.4 but not in 4.0.0, use -Os -msse2 to repeat:
-
void foo (int *j)
{
int __attribute__ ((mode (V2SI))) k;
long long t = (long long) k;
j[0] = t;
}
-
Note I cannot repeat this bug on 4.0.0 neither with this nor with Volker's
testcases, so I cleared 4.0 regression flag.
