* features/gdb-target.dtd (target): Accept an optional 'osabi'
element.
(osabi): Define element.
* features/mips-linux.xml (target): Add an osabi subelement set to
GNU/Linux.
* regformats/regdat.sh (xmlarch, xmlosabi): New variables. Don't
write the architecture into $xmltarget. Store it in $xmlarch.
Handle the 'osabi' type. Handle outputting the osabi element of
the target description.
* regformats/reg-x86-64-linux.dat (osabi): Set to GNU/Linux.
* regformats/reg-i386-linux.dat (osabi): Set to GNU/Linux.
* target-descriptions.h (tdesc_osabi, set_tdesc_osabi): Declare.
* target-descriptions.c (struct target_desc) <osabi>: New field.
(tdesc_osabi): New function.
(set_tdesc_osabi): New function.
* xml-tdesc.c: Include osabi.h.
(tdesc_end_osabi): New.
(target_children): Parse "osabi" elements.
* arch-utils.c (gdbarch_info_fill): Try to get the osabi from the
target description if the user didn't override it or it is not
extractable from the bfd. If that still fails, fallback to the
configured in default.
* osabi.h (osabi_from_tdesc_string): Declare.
* osabi.c (osabi_from_tdesc_string): New.
(gdbarch_lookup_osabi): Return GDB_OSABI_UNKNOWN instead of
GDB_OSABI_DEFAULT.
* NEWS: Mention that target descriptions can now describe the
target OS ABI.
2009-07-20 Pedro Alves <pedro@codesourcery.com>
* gdb.texinfo (Target Description Format): Mention the new <osabi>
optional element.
(subsection OS ABI): New subsection.
