readelf/objdump: support for SFrame section
This patch adds support for SFrame in readelf and objdump. The arguments of --sframe are optional for both readelf and objdump. include/ChangeLog: * sframe-api.h (dump_sframe): New function declaration. ChangeLog: * binutils/Makefile.am: Add dependency on libsframe for readelf and objdump. * binutils/Makefile.in: Regenerate. * binutils/doc/binutils.texi: Document --sframe=[section]. * binutils/doc/sframe.options.texi: New file. * binutils/objdump.c: Add support for SFrame format. * binutils/readelf.c: Likewise. * include/sframe-api.h: Add new API for dumping .sframe section. * libsframe/Makefile.am: Add sframe-dump.c. * libsframe/Makefile.in: Regenerate. * libsframe/sframe-dump.c: New file.
