Enhance GAS's .section directive so that it can take numeric values for the flags and type fields. (ELF only)
...
gas * doc/as.texinfo (.section): Document that numeric values can now
be used for the flags and type fields of the ELF target's .section
directive. Add notes about the restrictions on setting flags and
types.
* config/obj-elf.c (obj_elf_change_section): Allow known sections
to be given processor specific section types. Allow processor and
application specific flags of a section to be set after
definition.
(obj_elf_parse_section_letters): Handle parsing numeric values.
(obj_elf_section_type): Handle parsing numeric values.
(obj_elf_section): Allow numeric type values.
* config/obj-elf.h (obj_elf_change_section): Update prototype.
* testsuite/gas/elf/section10.d: New test.
* testsuite/gas/elf/section10.s: Source file for new test.
* testsuite/gas/elf/elf.exp: Run the new test.

the description of the flags produced by readelf.
* testsuite/gas/tic6x/scomm-directive-4.d: Likewise.
* NEWS: Mention the new feature.
bfd * elf-bfd.h (struct bfd_elf_special_section): Use unsigned values
for length and type fields. Use a signed value for the
suffix_length field.
binutils* readelf.c (get_section_type_name): Add hex prefix to offsets
printed for LOPROC and LOOS values. Ensure that a result is
always returned for the V850 target, even when an unrecognised
processor specific value is encountered.
(process_section_headers): Display key values in the order in
which they appear to the user. Add the "C (compressed)" value to
the list.
