[Bug target/37362] New: [4.4 Regression] Bootstrap broken on mipsisa64r2-linux-gcc

[g0dsowncountry at yahoo dot com]

This looks very similar to Bug# 33635. 

Stage 1 GCC (version 4.4.0 20080829) doesn't bootstrap on mipsisa64r2-linux-gcc
due to an ICE while compiling: -

mipsisa64r2-linux/64/libgcc/_powitf2.o 
mipsisa64r2-linux/libgcc/_powitf2.o    (n32)

[Identical Test Case from 33635]

[$] cat foo.i
void __powitf2 (float x __attribute__ ((mode (TF)))) {}

[$] ./gcc/cc1 -fpreprocessed foo.i -quiet
foo.i: In function '__powitf2':
foo.i:1: error: unrecognizable insn:
(insn 25 24 3 foo.i:1 (set (mem/c/i:DI (reg/f:SI 30 $fp) [0 x+0 S8 A128])
        (unspec:DI [
                (reg:TF 44 $f12 [ x ])
            ] 31)) -1 (nil))
foo.i:1: internal compiler error: in extract_insn, at recog.c:1988
