dynrelro section for read-only dynamic symbols copied into executable

Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library.  Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.

The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole.  This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.

The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

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.

MIPS16: Remove "extended" BREAK/SDBBP handling

Remove special casing for the `6' operand code used for the embedded
trap code of the BREAK and the SDBBP instructions to support supposedly
extended forms of these instructions.

According to all versions of the MIPS16 ASE specifications these
instructions are not extensible [1][2][3][4][5][7][8][10][11], 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 [5][6][9][10].

Therefore supposedly extended BREAK and SDBBP instructions do not serve
their purpose anymore as they do not cause a Bp and a Debug exception
respectively and supporting these forms in disassembly only causes
confusion.

MIPS16/GAS: Fix forced size suffixes with argumentless instructions

Correct the handling of `.e' and `.t' instruction size suffixes with
instruction mnemonics which are not followed by any text on the same
line, such as arguments or white space, e.g.:

$ cat test.s
.set mips16
foo:
entry.t # comment
entry.t
exit.t # comment
exit.t
nop.t # comment
nop.t
$ as -32 -o test.o test.s
test.s: Assembler messages:
test.s:4: Error: unrecognized opcode `entry.t'
test.s:6: Error: unrecognized opcode `exit.t'
test.s:8: Error: unrecognized opcode `nop.t'

MIPS16/GAS: Disallow EXTEND delay-slot scheduling

Do not allow any explicitly coded EXTEND instruction to be automatically
scheduled into a jump delay slot, as an EXTEND prefix is coupled with
the next regular MIPS16 instruction and therefore swapping it with a
jump would change program's semantics; EXTEND is not architecturally
allowed to be present in a jump delay slot anyway.

opcodes: Use autoconf to check for `bfd_mips_elf_get_abiflags' in BFD

Fix a regression introduced with commit 5e7fc731f80e ("MIPS/opcodes:
Also set disassembler's ASE flags from ELF structures"), further updated
with commit 4df995c77118 ("MIPS/opcodes: Also set disassembler's ASE
flags from ELF structures"), and use autoconf to check for the presence
of `bfd_mips_elf_get_abiflags' in BFD.

opcodes/
* mips-dis.c (set_default_mips_dis_options): Use
HAVE_BFD_MIPS_ELF_GET_ABIFLAGS rather than BFD64 to guard the

* configure.ac: Check for `bfd_mips_elf_get_abiflags' in BFD.
* Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add `libbfd.la'.
* aclocal.m4: Regenerate.

Fix more cases of improper test names

I noticed more occurrences of improper test names. The rather mechanical,
tedious and large patch below addresses, hopefully, most of the leftover cases.

As usual, another pair of eyes is welcome to check if missed something or did
an invalid substitution.

This patch also fixes the prepare_for_testing calls to pass proper test names.

Fix incorrect reference to source files

gdb/gdbserver/ChangeLog:

2016-12-23  Luis Machado  <lgustavo@codesourcery.com>

* win32-i386-low.c: Fix incorrect reference to a couple source files.
* nto-x86-low.c: Likewise.

Bump gold version number to 1.14.

* NEWS: Add new features in 1.14.
* version.cc (version_string): Bump to 1.14.

Call target specific add_symbols function

This allows targets that have target specific code to add object
symbols to make use of the generic archive handling.

* linker.c (generic_link_check_archive_element): Call target
bfd_link_add_symbols to add element symbols.

Remove "collect" forms of generic linker add symbols functions

Nothing calls them and they were in the way of a bug fix.

* linker.c (generic_link_add_symbols): Delete.  Merge into..
(_bfd_generic_link_add_symbols): ..here.
(generic_link_check_archive_element_no_collect): Delete.
(generic_link_check_archive_element_collect): Likewise.
(generic_link_add_object_symbols): Remove "collect" param.  Update
callers.
(generic_link_add_symbol_list): Likewise.
(generic_link_check_archive_element): Likewise.  Call
bfd_link_add_symbols rather than generic_link_add_object_symbols.
* libbfd-in.h (_bfd_generic_link_add_symbols_collect): Delete.
* libbfd.h: Regenerate.

hppa-linux-gnu-ranlib: libcpp.a: File format not recognized

This stops an --enable-targets selection affecting the main target in
regards to forcing 64-bit archives.  It also means mips64 and s390x
will revert to binutils-2.25 and binutils-2.26 behaviour of not
forcing 64-bit archives at least in the common case when plugins were
enabled.

PR binutils/20464
PR binutils/14625
* configure.ac: Revert 2016-05-25 configure change setting
want_64_bit_archive for mips64 and s390x.  Revise USE_64_BIT_ARCHIVE
description.
* configure: Regenerate.
* config.in: Regenerate.

Updated email address.

[msp430] Sync tc-msp430.c with devices.csv

This patch syncs the generated data structure in tc-msp430.c with the
latest version of devices.csv released by TI.

My understanding is that the devices being removed were "invalid spins",
so can't be being used by anyone, and never will be. Current web
searches related to these devices return no relevant results.

Built and tested (no regressions) as follows:
  Configured with: --target=msp430-elf --disable-gdb
  Test variations:
    msp430-sim/-mcpu=msp430
    msp430-sim/-mcpu=msp430x
    msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either
    msp430-sim/-mhwmult=none
    msp430-sim/-mhwmult=f5series

* config/tc-msp430.c (msp430_mcu_data): Sync with data from TI's
devices.csv file as of September 2016.

Fix placement of forced local symbols in the dynamic symbol table.

Gold was not placing forced-local symbols (e.g., hidden visibility)
at the front of the dynamic symbol table, or including them in the
count of local symbols recorded in the .dynsym section's sh_info field.

Fix problem where version script causes predefined hidden symbol to be defined twice.

When creating a predefined hidden symbol like _GLOBAL_OFFSET_TABLE_, gold
was incorrectly letting a version script add a version to the symbol,

Class-ify ui_out

This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy.  ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.

In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.

It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

ChangeLog formatting fixes

Support aligning text section from odd addresses

Previously, the alignment directives were not correctly supported
in the text section when current alignment was only 1 byte (i.e.,
when the address was odd).  Since there are no 1-byte instructions
in RISC-V, this patch resolves the bug by writing a zero byte to
obtain 2-byte alignment, at which point a 2-byte NOP can be used
to obtain 4-byte alignment.

Resolves https://github.com/riscv/riscv-gnu-toolchain/issues/205

* config/tc-riscv.c (riscv_make_nops): Emit 2-byte NOPs.

Avoid creating symbol table entries for registers

Instructions like "jal t0, foo" were erroneously creating symbol table
entries for t0 as well as foo, which causes linking problems.  Fix by
reordering instruction alternatives so that t0 is first attempted to
be parsed as a register, rather than as a symbol.

* riscv-opc.c (riscv_opcodes): Reorder jal and call entries.

Do not add padding if an output section is marked as ignored

* ldlang.c (size_input_section): Avoid calling insert_pad
if output_section_statement->ignored is set.

Fix longjmp across readline w/ --enable-sjlj-exceptions toolchains

Nowadays, GDB propagates C++ exceptions across readline using
setjmp/longjmp 89525768cd08 ("Propagate GDB/C++ exceptions across
readline using sj/lj-based TRY/CATCH") because DWARF-based unwinding
can't cross C functions compiled without -fexceptions (see details
from the commit above).

Unfortunately, toolchains that use SjLj-based C++ exceptions got
broken with that fix, because _Unwind_SjLj_Unregister, which is put at
the exit of a function, is not executed due to the longjmp added by
that commit.

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

the ISA level required actually recorded in the binary examined.

In assembly disallow size enforcement suffixes as appropriate: `.t' for

Re-work RISC-V gas flags: now we just support -mabi and -march

We've decided to standardize on two flags for RISC-V: "-march" sets the
target architecture (which determines which instructions can be
generated), and "-mabi" sets the target ABI.  We needed to rework this
because the old flag set didn't support soft-float or single-float ABIs,
and didn't support an x32-style ABI on RISC-V.

Additionally, we've changed the behavior of the -march flag: it's now a
lot stricter and only parses things we can actually understand.
Additionally, it's now lowercase-only: the rationale is that while the
RISC-V ISA manual specifies that ISA strings are case-insensitive, in
Linux-land things are usually case-sensitive.  Since this flag can be
used to determine library paths, we didn't want to bake some
case-insensitivity in there that would case trouble later.

This patch implements these two new flags and removes the old flags that
could conflict with these.  There wasn't a RISC-V release before, so we
want to just support a clean flag set.

Rework RISC-V relocations

Before this commit we didn't cleanly support CFI directives because the
internal offsets used to get relaxed which broke them.  This patch
significantly reworks how we handle linker relaxations:

 * DWARF is now properly supported

 * There is a ".option norelax" to disable relaxations, for when users
   write assembly that can't be relaxed (if it's to be later patched up,
   for example).

 * There is an additional _RELAX relocation that specifies when previous
   relocations can be relaxed.

We're in the process of documenting the RISC-V ELF ABI, which will
include documentation of our relocations

  https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md

but we expect that this relocation set will remain ABI compatible in the
future (ie, it's safe to release).

Thanks to Kuan-Lin Chen for figuring out how to correctly relax the
debug info!
