Some MIPS targets use a named section symbol rather than a symbol with
no name as is used with most ELF targets. When renaming sections, the
named section symbol needs to be renamed too.
Rather than fix this bug, I'd originally intended to just correct the
xfail added recently for update-1.o vs update4.o in update-section.exp,
using the same set of targets for the localize-hidden-1 mips xfail.
I'd extracted that target test into a new function, is_bad_symtab. It
turns out to be useful in readelf.exp too.
bfd/
* config.bfd: Delete mips vxworks patterns matched earlier.
Combine mips*-*-none with mips*-*-elf*.
binutils/
* objcopy.c (find_section_rename): Forward declare. Remove
ibfd and sec_ptr param. Add old_name param. Allow for NULL
returned_flags. Move read of section name and flags to..
(setup_section): ..here. Update find_section_rename call.
(filter_symbols): Rename section symbols for renamed sections.
(copy_object): Call filter_symbols when renamed sections.
* testsuite/lib/binutils-common.exp (is_bad_symtab): New.
* testsuite/binutils-all/update-section.exp: Revert 96037eb0
mips xfail.
* testsuite/binutils-all/objcopy.exp (copy_executable): Use
is_bad_symtab.
(localize-hidden-1): xfail if is_bad_symtab.
* testsuite/binutils-all/readelf.exp: Use is_bad_symtab to select
between mips/tmips.
* testsuite/binutils-all/ar.exp: Skip tests for Alpha target.
Skip bfdtest1 tests for tic30 target.
* testsuite/binutils-all/arm/objdump.exp: Skip for aout arm
target.
* testsuite/binutils-all/compress.exp: Expect some tests to fail
on the nds32.
* testsuite/binutils-all/copy-3.d: Skip for go32 targets.
* testsuite/binutils-all/copy-4.d: Skip for AIX and linuxecoff
targets.
* testsuite/binutils-all/nm.exp: Treat beos based targets as ELF
targets.
* testsuite/binutils-all/objcopy.exp: Only run reverse bytes tests
if the bintest.o file was created. Use the
get_standard_section_names proc to get the name of the data
section.
* testsuite/binutils-all/objdump.exp: Update regexps to allow for
RX section names.
* testsuite/binutils-all/readelf.exp: Use
get_standard_section_names proc to get the name of the data
section.

section names.
* testsuite/binutils-all/readelf.s: Update regexps for tilepro.
* testsuite/binutils-all/size.exp: Allow for non standard section
names.
* testsuite/binutils-all/update-section.exp: Expect comapre 1vs4
to fail on mips targets.
* testsuite/lib/utils-lib.exp (default_binutils_run): Use
get_standard_section_names proc.
(run_dump_test): Likewise.
(proc get_standard_section_names): New proc.
New option for objcopy --update-section allows the contents of a section
to be updated while maintaining the section flags, and, for ELF files,
the section to segment mapping.
New test uses --dump-section and --update-section to check that a
section can be made larger and smaller with an update.
