e5713223cb MIPS/BFD: For n64 hold the number of internal relocs in `->reloc_count'
Revert parts of commit fee24f1c5b ("objdump improvements for mips
elf64"), <https://sourceware.org/ml/binutils/2003-03/msg00108.html>, and
make the `->reloc_count' member of `struct bfd_section' hold the actual
number of internal relocations stored in its `->relocation' vector.  To
do so adjust `mips_elf64_slurp_one_reloc_table' to set `->reloc_count'
to the actual number of internal relocations retrieved and discard
`mips_elf64_canonicalize_reloc', `mips_elf64_canonicalize_dynamic_reloc'
and their corresponding target macros.  Contrary to the description of
`mips_elf64_slurp_one_reloc_table', adjusted appropriately, this makes
generic relocation processing code happy and satisfies the "merge notes
section" binutils test case.

Add extra binutils test cases to expand the coverage of the generic
"merge notes section" test case, now passing with the n64 ABI, across
the MIPS o32, n32 and n64 ABIs regardless of the default ABI selected in
target configuration, and also to verify correctness of the relocations
produced.  Conversely, do not provide any additional test cases for the
original issue addressed with the commit referred:

- objdump would display only 1/3 of the total number of relocations,
  because it used the external relocation count, but each external
  relocation is brought in as 3 internal relocations.

as n64 ABI relocation processing with `objdump -r' and `objdump -R' is
already widely covered across the GAS and LD test suites.

f0681695da binutils/testsuite: Permit the reuse of dump patterns
Complement commit 89210bdc8f ("GAS: Permit the reuse of dump
patterns"), <https://sourceware.org/ml/binutils/2010-07/msg00269.html>,
and commit ef2b5578f6 ("MIPS: Enable NewABI tests for SDE targets"),
<https://sourceware.org/ml/binutils/2012-08/msg00017.html>, and like the
GAS and LD versions make the binutils version of `run_dump_test' also
support the `dump' keyword, for reusing dump patterns between tests.

a91e1603af Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX
Mark an ALLOC section, which should be placed in special memory area,
with SHF_GNU_MBIND.  Its sh_info field indicates the special memory
type.  GNU_MBIND section names start with ".mbind" so that they are
placed as orphan sections by linker.  All input GNU_MBIND sections
with the same sh_type, sh_flags and sh_info are placed in one output
GNU_MBIND section.  In executable and shared object, create a
GNU_MBIND segment for each GNU_MBIND section and its segment type is
PT_GNU_MBIND_LO plus the sh_info value.  Each GNU_MBIND segment is
aligned at page boundary.

The assembler syntax:

    .section .mbind.foo,"adx",%progbits
                          ^             0: Special memory type.
                          |
                         'd' for SHF_GNU_MBIND.

    .section .mbind.foo,"adx",%progbits,0x1
                          ^             1: Special memory type.
                          |
                         'd' for SHF_GNU_MBIND.

    .section .mbind.bar,"adG",%progbits,.foo_group,comdat,0x2

0674ee5dad MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.

According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].

Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

11dd08e9a0 MIPS16/opcodes: Respect ISA and ASE in disassembly
Limit MIPS16 instruction disassembly according to the ISA level and ASE
set selected, as with the regular MIPS and microMIPS instruction sets.
Retain the property of `objdump -m mips:16' disassembling all MIPS16
instructions however, regardless of any ISA level recorded in the binary
examined.

To validate the disassembler use the GAS test suite for its convenience
of running tests across multiple ISAs, even though placing the tests in
the binutils test suite would be more appropriate.  Adjust the single
binutils test which depends on 64-bit instruction disassembly to have
the ISA level required actually recorded in the binary examined.

	opcodes/
	* mips-dis.c (mips_arch_choices): Use ISA_MIPS64 rather than
	ISA_MIPS3 as the `isa' selection in the `bfd_mach_mips16' entry.
	(print_insn_mips16): Check opcode entries for validity against
	the ISA level and ASE set selected.

	rather than `.set' to set the ISA level.

7fd5392005 MIPS16: Switch to 32-bit opcode table interpretation
Switch to 32-bit MIPS16 opcode table entry interpretation, similar to
how the microMIPS opcode table is handled, for both the `match' and
`mask' fields, removing special casing for JAL and JALX instructions and
their `a' and `i' operand codes throughout, while retaining automatic
processing of extendable opcodes in assembly and disassembly.

In assembly disallow size enforcement suffixes as appropriate: `.t' for
both 32-bit instructions and macros and `.e' for macros only, making
macro handling consistent with the microMIPS instruction set.

In disassembly fully decode EXTEND prefixes prepended to unsupported
instruction encodings (according to the ISA selection) rather than
dumping them as hexadecimal data along with the following instruction,
removing all special casing for the EXTEND prefix and making its
handling rely on its opcode table entry, except where it is considered a
part of an extendable instruction.

	include/
	* opcode/mips.h (mips_opcode_32bit_p): New inline function.

	gas/
	* config/tc-mips.c (micromips_insn_length): Use
	`mips_opcode_32bit_p'.

	(append_insn): Adjust forced MIPS16 instruction size
	determination.
	(match_mips16_insn): Likewise.  Don't shift the instruction's
	opcode with the `a' and `i' operand codes.  Use
	`mips_opcode_32bit_p' in operand decoding.
	(match_mips16_insns): Check for forced instruction size's
	validity.

5e7fc731f8 MIPS/opcodes: Also set disassembler's ASE flags from ELF structures
Respect any ASE flags recorded in ELF file structures for the purpose of
selecting instructions to be disassembled, preventing code from being
hex-dumped even though having been clearly indicated as valid at the
assembly time.  Use date from the MIPS ABI flags structure if present,
and otherwise there may be an MDMX ASE flag set in the ELF file header.
For backwards compatibility only set extra flags and do not clear any,
preserving all previously set by the architecture selected to be
disassembled for.

d3e5f6c8f1 objcopy/strip: Add option --remove-relocations=SECTIONPATTERN
The objcopy and strip tools make use of the bfd library to manipulate
the state of the input file (to produce an output file).  Within the
input file (for ELF at least), relocations are held within a section,
and so, if the user wanted to remove the relocations, but keep the
section to which the relocations would have been applied, it is tempting
to think that specifying the name of a relocation section to objcopy's
--remove-section option might do what you want, for example:

   objcopy --remove-section=.rela.text input.elf output.elf

However, this does not work.  The reason is that when the input file is
loaded, relocations are not managed as sections, but are, instead,
loaded as data associated with the section to which the relocations
would be applied.  In our example above the relocations in '.rela.text'
are held as data on the section '.text' once 'input.elf' is loaded.

One task that objcopy and strip do is copy the relocations from the
input file to the output file if the section is also being copied from
the input file to the output file.

This commit adds a new command line option for objcopy and strip,
--remove-relocations, which can be used to remove the relocations, while
keeping the section that the relocations would have been applied to, for
example:

    objcopy --remove-relocations=.text input.elf output.elf

in this case the section '.text' will appear in both 'input.elf' and
'output.elf', but any relocations in 'input.elf' that apply to '.text'
will not be present in 'output.elf'.

I have also added a special case to the handling of --remove-section
that spots if a user tries to remove a relocation section (currently
this is done by spotting the '.rela.' or '.rel.' prefix) and forwards
the request to --remove-relocations.

As with --remove-section and --only-section the --remove-relocations
option supports the '!' prefix on the section-patterns it takes to allow
for sections to be specifically not matched.

There are tests for all the new functionality.

e511c9b19f objcopy/strip: Allow section patterns starting with '!'.
For symbol matching, prefixing a pattern with '!' will indicate a
non-matching pattern, however, this is not the case for section
patterns.  As a result it is not possible to say "apply this action to
all sections except ...".

With this commit the objcopy and strip tools now support '!' prefix for
section patterns, so we can say:

  objcopy --remove-section="*" --remove-section="!.text*"

Which will remove all sections, except those matching the pattern
'.text*'.

	* objcopy.c (find_section_list): Handle section patterns starting
	with '!' being a non-matching pattern.

9cc0123fea MIPS objcopy --rename-section fix
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.

1401d2fe67 MIPS/opcodes: Correct mixed MIPS16 and microMIPS disassembly
Mixing MIPS16 and microMIPS code in a single binary isn't usually
supported but GAS happily produces such code if requested.  However it
is not correctly disassembled even if a symbol table is available and
function symbols are correctly anotated with the ISA mode.  This is
because the ELF-header global microMIPS ASE flag takes precedence over
MIPS16 function annotation, causing them to be treated as regular MIPS
code.

Correct the problem by respecting function symbol anotation regardless
of the ELF-header flag.
