[BUILDROBOT] m86k breakage

[Jan-Benedict Glaw]

Hi Alan,

I observed that with a new-enough compiler, recent m68k builds break
(see eg.
http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=329738):

 gcc -DHAVE_CONFIG_H -I. -I/home/vaxbuild/repos/binutils_gdb/gas  -I. -I/home/vaxbuild/repos/binutils_gdb/gas -I../bfd -I/home/vaxbuild/repos/binutils_gdb/gas/config -I/home/vaxbuild/repos/binutils_gdb/gas/../include -I/home/vaxbuild/repos/binutils_gdb/gas/.. -I/home/vaxbuild/repos/binutils_gdb/gas/../bfd -DLOCALEDIR="\"/home/vaxbuild/build/m68k-linux/_install_/share/locale\""  -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Werror -g -O2 -MT read.o -MD -MP -MF .deps/read.Tpo -c -o read.o /home/vaxbuild/repos/binutils_gdb/gas/read.c
/home/vaxbuild/repos/binutils_gdb/gas/read.c: In function ‘parse_mri_cons’:
/home/vaxbuild/repos/binutils_gdb/gas/read.c:3869:20: error: right-hand operand of comma expression has no effect [-Werror=unused-value]
   (expression (EXP), TC_PARSE_CONS_RETURN_NONE)
                    ^
/home/vaxbuild/repos/binutils_gdb/gas/read.c:4608:5: note: in expansion of macro ‘TC_PARSE_CONS_EXPRESSION’
     TC_PARSE_CONS_EXPRESSION (exp, nbytes);
     ^
cc1: all warnings being treated as errors


I think this is caused by the "gas TC_PARSE_CONS_EXPRESSION
communication with TC_CONS_FIX_NEW" commit (April 8th). Don't have a
tested patch yet...  Maybe I'll look into it tomorrow.

MfG, JBG
