This ICE occured during a compile of libfloat with mainline.
Attached is a delta reduced test that produces the ICE when compiled with -O2.
softfloat/bits64/softfloat.c: In function float128_rem:
softfloat/bits64/softfloat.c:4483: internal compiler error: in
compare_name_with_value, at tree-vrp.c:3064
__inline__ void
shift128Right (int count, long long int *z1Ptr)
{
long long int z1;
if (count == 0);
else if (count < 64);
else
z1 = (count < 64) ? count : 0;
*z1Ptr = z1;
}
float128_rem ()
{
signed int expDiff;
long long int aSig1;
long long int sigMean1;
if (-64 < expDiff)
shift128Right (-expDiff, &aSig1);
add128 (&sigMean1);
}
