------- Additional Comments From pinskia at gcc dot gnu dot org 2005-09-24 20:09 -------
Confirmed, reduced testcase:
int DES_CBCUpdate(unsigned char * output, int len)
{
int work[2];
unsigned int i;
for(i = 0;i < len/8;i++)
unscrunch (&output[8*i], work);
}
Only "-O1 -ftree-vectorize --param ggc-min-heapsize=0 --param ggc-min-expand=0" is needed to
reproduce this bug.
