I have seen this in other cases even for the non doloop case, though I don't
know if it is because of -O1 or because it is not removing it.
Testcase:
int _bfd_xcoff_canonicalize_dynamic_reloc (unsigned long long l_symndx)
{
if (l_symndx < 3)
{
switch (l_symndx)
{
case 0:
case 1:
break;
case 2:
return _bfd_abort ();
}
}
}
--- CUT ---
Compile at -O1 on powerpc-linux and you will see the double branches:
bne 0,.L7
bne 0,.L8
