[Bug c/41151] New: Gas fails to consume the assembly Error: offset too big

[raj dot khem at gmail dot com]

When compiling the test program 

arm-none-linux-gnueabi-gcc -march=armv7-a -O2 -c -o ltest.o ltest.i

Assembler fails to assemble it and emits the error 

Error: offset too big

If I do not use -march=armv7-a it works ok and also if I dont use O2 it
compiles fine.

Using binutils trunk as well as r150986 I can't reproduce this with -O2 and
-march=armv7-a.

I was using 2.18. I haven't tried 2.19 but it works ok with binutils from
cvs(updated from today)

My experience:
gcc 4.4 + binutils 2.18.50.20070820 + no -march: ok
gcc 4.4 + binutils 2.18.50.20070820 + -march=armv7-a: error
gcc 4.4 + binutils 2.19.51.0.2.20090204: ok in both cases

The instruction I had problems with was:
        movw    r1, #:lower16:_ZL18qt_resource_struct

My guess is that gcc started generating these instructions for newer ARM
models, but binutils 2.18 couldn't consume them properly. But since it works
with a newer binutils, my guess is that the problem is fixed.

Needed an update to a newer version of binutils. Invalid.
