I'm having a problem when compiling with the stage1 compiler.
loop optimization is trying to generate an insn to set a CCmode reg to
CONST_INT 1 like this:
start_sequence ();
emit_move_insn (m->set_dest, m->set_src);
temp = get_insns ();
end_sequence ();
and emit_move_insn calls gen_movcc, which fails:
(define_expand "movcc"
[(set (match_operand:CC 0 "nonimmediate_operand" "")
(match_operand:CC 1 "move_operand" ""))]
""
"
{
if (! reload_in_progress && ! reload_completed)
FAIL;
}")
Any suggestions?
Andrew.

See config/ia64/build.hacks. Jim has tried at least three
different methods for solving that problem, but does not
yet have anything he's happy with.
