--- Comment #4 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> ---
Code around tree-ssa-loop-manip.c:1049 (in determine_exit_conditions) is:
else if (cmp == GT_EXPR)
{
gcc_assert (tree_int_cst_sign_bit (step));
}
which seems checking: 'step' should be negative if 'cmp' is ">"
code around pr101145.c:6 :
5unsigned __attribute__ ((noinline))
6foo (int *__restrict__ a, int *__restrict__ b, unsigned l, unsigned n)
7{
8 while (n < ++l)
9 *a++ = *b++ + 1;
10 return l;
11}
------------
I did not find arm big-endian yet, I'm trying to reproduce this issue on other
targets...
