[Bug middle-end/25248] [4.1/4.2 Regression] 2.6.15-rc4 arch/powerpc/mm/hash_utils_64.c miscompiled

------- Comment #14 from bergner at vnet dot ibm dot com  2005-12-06 13:40 -------
sizeof(unsigned long) and sizeof(unsigned long long) are both 8 bytes on ppc64.

Olaf, -O1 isn't a workaround, it's the minimum optimization level that still
shows the bug.  Trying some -fno-* options, using -fno-tree-loop-optimize makes
the problem go away at least on the test case:

bergner@vervain:~/PR25248> gcc4.1 -m64 -O2 -fno-tree-loop-optimize
hash_utils_64.c
bergner@vervain:~/PR25248> ./a.out
addr = 0x0000000000001000
