I have checked out trunk 148941, compiled binutils with it (configured
with --disable-werror), ran the testsuite and there were no failures.
Thus I consider this fixed.

The miscompiled file seems to be gas/tc-i386.o. Early SRA is enough to trigger
the problem. Digging deeper...

This is probably the same bug: binutils 2.19.51.20090616 (build, host:
i686-pc-linux-gnu, target: i686-pc-mingw32), compiled with GCC 4.5.0 20090618.
GAS aborts when tries to assemble this instruction:

Right, now I can reproduce the problem and it indeed is introduced by the new
SRA commit. None of the fixes I have done so far deals with this one either. I
am investigating this further (but don't hold your

I will look into this next week. However, I have never compiled binutils
before, so unless it is obvious, please describe how to reproduce the problem.

With 148536 and current mainline cvs binutils I see no failures in the gas

Revision 148512 failed to build binutils. You may need to remove -Werror
