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
Please submit a full bug report,
