The attached test case produces this warning:

$ gcc -save-temps -O2 shortened.c -o shortened
shortened.s: Assembler messages:
shortened.s:21: Warning: 00000003fffffffc shortened to 00000000fffffffc

This only happens with -O2, not with -O0 or -O1.

I can reproduce this on the following versions (these are all from prebuilt
Debian packages):
gcc-4.0 (GCC) 4.0.4 20060507 (prerelease) (Debian 4.0.3-3)
gcc-4.1 (GCC) 4.1.2 20061028 (prerelease) (Debian 4.1.1-19)

The following versions seem to be unaffected:
gcc-3.4 (GCC) 3.4.6 (Debian 3.4.6-5)
gcc-4.2 (GCC) 4.2.1 20070627 (prerelease) (Debian 4.2-20070627-1)

------- Comment #3 from manu at gcc dot gnu dot org  2010-02-21 00:48 -------
4.1.x is already too old, so if you cannot reproduce it in a recent version, we
consider this FIXED.
