------- Comment #4 from rguenth at gcc dot gnu dot org 2008-12-02 12:21 -------
Minimal testcase:
unsigned _ov_64_seek_lap (_Bool x1, _Bool x2, _Bool x3)
{
unsigned ltmp_3978_7__PHI_TEMPORARY;
unsigned ltmp_4011_7__PHI_TEMPORARY;
signed ltmp_4011_7;
if (!x1 || !x2)
while (1) ;
if (x3)
ltmp_3978_7__PHI_TEMPORARY = 0xffffff7e;
else
ltmp_3978_7__PHI_TEMPORARY = 1;
ltmp_4011_7 = -1;
return ltmp_4011_7 >> ltmp_3978_7__PHI_TEMPORARY;
