mips-sgi-irix6.5
>Description:
Test g77.f-torture/execute/labug1.f compilation fails for mips-sgi-irix6.5 -mabi=64 with -O2 and -O3.  This is a regression from gcc-3.0.

The failure was introduced between 20010501 and 20010507.  It may be related to PR fortran/3392.

Compiler output is:

labug1.f: In program `labug1':
labug1.f:42: Unrecognizable insn:
(insn 670 276 367 (set (reg:DI 254)
        (plus:DI (reg:DI 254)
            (sign_extend:DI (const_int 50 [0x32])))) -1 (nil)
    (nil))
labug1.f:42: Internal compiler error in extract_insn, at recog.c:2173

>How-To-Repeat:
bootstrap and run g77 testsuite with -mabi=64
