Description sugioka 2004-05-12 14:30:51 UTC 
The attached code ICE's with '-m4 -O2 -fPIC'.

$ sh-linux-gcc -O2 -fPIC -m4 -c XExtInt.i
XExtInt.c: In function `XInputWireToEvent':
XExtInt.c:663: error: unrecognizable insn:
(insn 2736 2735 2737 (unspec_volatile [
            (label_ref 775)
            (const_int 0 [0x0])
        ] 4) -1 (nil)
    (nil))
XExtInt.c:663: internal compiler error: in insn_default_length, at insn-
attrtab.c:709

It correctly compiles with '-m4 -O -fPIC'.
