           Summary: Large assembly output values with X-MAME code.
           Product: gcc
           Version: 3.3.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org

Hello,

  When trying to compile various files of the X-MAME project with gcc 3.3.2
(latest prerelease in Debian sid) as well as older versions, I often got errors
similar to this:

superpac.s: Assembler messages:
superpac.s:384: Error: value of ffffffffffffff7f too large for field of 1 bytes 

  I've isolated one of these files, reduced the command line options needed to
cause the problem to a minimum, and the result follows:

$ gcc -v -save-temps -O2 -fomit-frame-pointer -funroll-loops -march=k6-2
-DINLINE= -Isrc -Isrc/unix -o xmame.obj/vidhrdw/superpac.o -c src/vidhrdw/superpac.c

  I'm attaching the preprocessed source code, you should be able to reproduce
the problem with "gcc -O2 -fomit-frame-pointer -funroll-loops -march=k6-2".

Thanks,
