I don't think INSN_UID is right for that, I think you want to preserve the
original order of debug insns in that case, and INSN_UID can jump up and down.
So what about
if (MAY_HAVE_DEBUG_INSNS)
{
/* Schedule debug insns as early as possible. */
if (DEBUG_INSN (tmp))
{
if (DEBUG_INSN (tmp2))
return INSN_LUID (tmp) - INSN_LUID (tmp2);
return -1;
}
else if (DEBUG_INSN (tmp2))
return 1;
}
?
