--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Even
void
bar (unsigned char e)
{
bar (3);
unsigned char c;
c = -e;
}
ICEs with -O2 -fno-tree-dce the same way. So, the question is:
1) why on the #c0 testcase doesn't DCE do its job
2) why does the tailr pass consider it something that needs to be accumulated
(in a void temporary)
