Description Khem Raj 2010-06-20 22:00:55 UTC 
attached example fails to compile when no -O<n> is used.

$ arm-oe-linux-uclibceabi-gcc -mthumb -fPIC a.i -c
/tmp/cc1iMNtS.s: Assembler messages:
/tmp/cc1iMNtS.s:4814: Error: branch out of range

If -O1 or any other -O optlevel is used then it works fine.

Seen also with 4.6 and 4.5 arm-unknown-linux-gnueabi toolchains at -O0, 4.4 and 4.3 don't trigger it.

I'm pretty sure I've seen another thumb out of range branch PR not too long ago.
