             Bug #: 54436
           Summary: Compiling some regular C++ code gives assembler
                    '700415 shortened to 255' warning
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mathias@gaunard.com


Created attachment 28110
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28110
automatically reduced testcase

When I compile the attached C++ code with GCC 4.7 and GNU as 2.22 with -O1, I
get the following message:
$ g++ -O1 -c reversebits.ii
/tmp/cchfvrG0.s: Assembler messages:
/tmp/cchfvrG0.s:40: Warning: 700415 shortened to 255

I do not think it is normal that GCC does not report any problem while the
assembler does.

The attached testcase was unfortunately automatically reduced from a large code
base, so it isn't very readable. Sorry about that.
I also do not know what is the right component, so putting in 'other' for now.
