gas-971208 mips64orion-rtems internal error


The public domain floating point test paranoia when compiled by egcs 1.0
generates code which causes an internal error in gas.  I have cut the code
down to the following:

        .file   1 "p1.c"

 # -G value = 8, Cpu = 4650, ISA = 3
 # GNU C version egcs-2.90.21 971202 (egcs-1.00 release)
(mips64orion-rtems) compiled by GNU C version 2.7.2.
 # options passed:  -mcpu=4650
 # options enabled:  -fpeephole -ffunction-cse -fkeep-static-consts
 # -fpcc-struct-return -fcommon -fverbose-asm -fgnu-linker
-fargument-alias
 # -mgas -mfp64 -mgp64 -meb -mcpu=4650

gcc2_compiled.:
__gnu_compiled_c:
        .globl  One
        .align  3
One:
        .word   0x3ff00000              # 1
        .word   0x00000000
        .globl  paranoia
        .ent    paranoia
paranoia:
        .frame  $fp,72,$31              # vars= 8, regs= 3/1, args= 32,
extra= 0
        .mask   0xc0010000,-16
        .fmask  0x00100000,-8
        s.d     $f0,One

which when assembled as follows:

mips64orion-rtems-as -mcpu=4650 -v p1.s

generates this error message:

p1.s: Assembler messages:
p1.s:23: Internal error!
Assertion failure in macro_build at ../../src/gas/config/tc-mips.c line
2365.
Please report this bug.

This file assembles with a warning about the missing ".end or .bend" with
binutils 2.8.1.

Thanks.
