Subject: [ARC] Update warning reporting.
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=6af0448446f9212df4dc62e7618174d5d3f5e43e;p=deliverable%2Fbinutils-gdb.git

[ARC] Update warning reporting.

MWDT compiler doesn't use eflags and makes use of 0x0c section. For
those, silence the gnu warning system.

        * elf32-arc.c (arc_elf_merge_private_bfd_data): Complain about
        efalgs only when in/out exists.
        (elf32_arc_section_from_shdr): Don't complain about 0x0c section
        type.  It is mwdt compiler specific.
