These failures don't show up with gdbserver or native gdb on Linux because
they don't export any memory maps, therefore the vector of memory regions is
empty.
Outside of that scenario, we can't guarantee the absence of memory regions
reported by the target upon a connection. In our particular target, we
provide a memory map and the memory regions vector ceases to be empty.
With a non-empty memory regions vector, manipulating memory regions will cause
gdb to be more verbose and output text. For example:
memattr.c:require_user_regions
/* Otherwise, let the user know how to get back. */
if (from_tty)
warning (_("Switching to manual control of memory regions; use "
"\"mem auto\" to fetch regions from the target again."));
memattr.c:create_mem_region
if ((lo >= n->lo && (lo < n->hi || n->hi == 0))

|| (lo <= n->lo && ((hi >= n->hi && n->hi != 0) || hi == 0)))
{
printf_unfiltered (_("overlapping memory region\n"));
return;
}
In my particular case i got both of the above messages.
In order to fix this, i've moved the delete_memory proc from
gdb.base/memattr.exp to a new file lib/memory.exp and made lib/gdb.exp
load that file.
For both gdb.base/breakpoint-in-ro-region.exp and gdb.base/memattr.exp the
patch clears all existing memory regions after running to main. That way we
are guaranteed to have a clean state for memory regions so the tests can
exercise whatever they want and have an expected output pattern.

Big-endian hosts: Fix "set architecture cris"
The all-architectures-1.exp test case currently yields 66 FAILs on s390x,
because the "set architecture" command fails each time when attempting to
switch to "cris", "crisv32", or "cris:common_v10_v32". Actually, the
command would succeed if the endianness had been set to "little" before.
Instead, the test case sets the endianness to "auto", which results in
"big" on s390x.
So on x86_64:
(gdb) set endian auto
The target endianness is set automatically (currently little endian)
(gdb) set architecture cris
warning: A handler for the OS ABI "AIX" is not built into this configuration
of GDB. Attempting to continue with the default cris settings.
The target architecture is assumed to be cris
But on s390x:
(gdb) set endian auto
The target endianness is set automatically (currently big endian)
(gdb) set architecture cris
Architecture `cris' not recognized.
See also the test results for s390x and ppc64be:
https://sourceware.org/ml/gdb-testers/2016-q4/msg05150.html
https://sourceware.org/ml/gdb-testers/2016-q4/msg05713.html
Indeed, cris_gdbarch_init in cris-tdep.c returns a failure unless the
user-specified endianness is "little". Other architectures usually ignore
the user-specified endianness and return a valid gdbarch anyhow, even if
they can not really cope with the given endianness.
This patch removes the check in cris-tdep.c and forces little-endian byte
order instead.

Refactor gdb.reverse/insn-reverse.c
Changes in v2:

If we move forward with requiring more tests for record/replay on different

of differing arch-specific code in the same file.
I've broken up the main file into other files with arch-specific bits
(insn-reverse-<arch>.c). The main file will hold the generic pieces that will
take care of calling the tests.
The arch-specific c files are then included at the top of the generic c file.
I've also added a generic initialize function since we need to run pre-test
checks on x86 to make sure the rdrand/rdseed instructions are supported,
otherwise we will run into a SIGILL.
The arch-specific files will implement their own initialize function with
whatever makes sense. Right now the aarch64 and arm files have an empty
initialization function.

Fix crash when loading a core with unexpected register section size
When loading a core without an executable like so:
$ gdb --core core
for example often the gdbarch won't contain the
iterate_over_regset_sections method. For example on ARM.
This will generate a call to get_core_register_section with a NULL regset
like at corelow.c:628
get_core_register_section (regcache, NULL, ".reg", 0, 0, "general-purpose", 1);
However a check for REGSET_VARIABLE_SIZE in get_core_register_section
assumes that regset is != NULL thus leading to a crash with this backtrace:
(gdb) bt
#0 0x000000000065907b in get_core_register_section
(regcache=regcache@entry=0x2c26260, regset=regset@entry=0x0,
name=name@entry=0xdbf7b2 ".reg", min_size=min_size@entry=0,
which=which@entry=0, human_name=human_name@entry=0xdbac28
"general-purpose", required=1)
at ../../gdb/corelow.c:542
#1 0x0000000000659b70 in get_core_registers (ops=<optimized out>,

at ../../gdb/target.c:3590
Note that commit:
f962539ad23759 ("Warn if core file register
section is larger than expected") introduced this issue.
Thus releases > 7.8.2 are affected.
Also, this would have been caught by gdb.base/corefile.exp but the
problem is that this triggers only if the core dump is missing some data
so that it's not recognized as a linux core dump, or it's not a linux core
dump and the core file register section is larger than expected.
So if you just create a core and read it on linux with ARM the osabi is
detected properly and iterate_over_regset_sections is present and so the
problem is not triggered.
Thus creating a linux test for this with a crafted core that meets the
problem requirements is non-trivial.
This patch fixes this crash by adding a check for regset existence before
running the condition.

Don't throw exception in dis_asm_memory_error
Hi,
GDB calls some APIs from opcodes to do disassembly and provide some
call backs. This model makes troubles on C++ exception unwinding,
because GDB is a C++ program, and opcodes is still compiled as C.
As we can see, frame #10 and #12 are C++, while #frame 11 is C,
#10 0x0000000000544228 in memory_error (err=TARGET_XFER_E_IO, memaddr=<optimized out>) at ../../binutils-gdb/gdb/corefile.c:237

insn=0xffffffffed40, insn@entry=0xffffffffed90, flags=flags@entry=0,
C++ exception unwinder can't go across frame #11 unless it has
unwind table. However, C program on many architectures doesn't
have it in default. As a result, GDB aborts, which is described
in PR 20939.
This is not the first time we see this kind of problem. We've
had a commit
89525768cd086a0798a504c81fdf7ebcd4c904e1
"Propagate GDB/C++ exceptions across readline using sj/lj-based TRY/CATCH".
We can fix the disassembly bug in a similar way, this is the option one.
Since opcodes is built with gdb, we fix this problem in a different
way as we did for the same issue with readline. Instead of throwing
exception in dis_asm_memory_error, we record the failed memory
address, and throw exception when GDB returns from opcodes disassemblers.

Disassembly unit test: disassemble one instruction
This patch adds one unit test, which disassemble one instruction for
every gdbarch if available. The test needs one valid instruction of
each gdbarch, and most of them are got from breakpoint instruction.
For the rest gdbarch whose breakpoint instruction isn't a valid
instruction, I copy one instruction from the gas/testsuite/gas/
directory.
I get the valid instruction of most gdbarch except ia64, mep, mips,
tic6x, and xtensa. People familiar with these arch should be easy
to extend the test.
In order to achieve "do the unit test for every gdbarch", I add
selftest-arch.[c,h], so that we can register a function pointer,
which has one argument gdbarch. selftest.c will iterate over all

Refactor disassembly code
This patch addes class gdb_disassembler, and refactor
code to use it. The gdb_disassembler object is saved
in disassember_info.application_data. However,
disassember_info.application_data is already used by
gdb for arm, mips spu, and scm-disasm. In arm and mips,
.application_data is gdbarch, but we can still get gdbarch
from gdb_disassember.
The use of application_data in spu is a little bit
complicated. It creates its own disassemble_info, and
save spu_dis_asm_data in .application_data. This will
overwrite the pointer to gdb_disassembler, so we need
to find another place to save spu_dis_asm_data. I

Use dwarf assembler in gdb.dwarf2/implptr-64bit.exp
This patch adds a DW_OP_implicit_value in dwarf assembler, and uses
dwarf assembler in implptr-64bit.exp. Using dwarf assembler in
implptr-64bit.exp exposes some limitations in dwarf assembler,
- some variables are not evaluated in the caller's context, so we
can not pass variable to assembler, like this
Dwarf::assemble $asm_file {
cu {
version $dwarf_version
addr_size $addr_size
is_64 $is_64
} {
}
and
{DW_AT_type :$struct_label "DW_FORM_ref$ref_addr_size"}
this limitation is fixed by adding "uplevel" and "subst".
- dwarf assembler doesn't emit DW_FORM_ref_addr for label referencing.
this limitation is fixed by adding a new character "%",
{ type %$int_label }
this means we want to emit DW_FORM_ref_addr for label referencing.
- we can't set the form of label referencing offset in dwarf assembler.
Nowadays, dwarf assembler guesses the form of labels, which is
DW_FORM_ref4. However, in implptr-64bit.exp, both DW_FORM_ref4
and DW_FORM_ref8 is used (see REF_ADDR in implptr-64bit.S). This
patch adds the flexibility of setting the form of label reference.
Both of them below are valid,
{DW_AT_type :$struct_label}
{DW_AT_type :$struct_label DW_FORM_ref8}
the former form is the default DW_FORM_ref4.
I compared the .debug_info of objects without and with this patch

of section GC from `elf_gc_sweep' to `bfd_elf_size_dynamic_sections',

The rationale is it is enough if symbols are swept at the beginning of
`bfd_elf_size_dynamic_sections' as it is only in this function that the
size of the GOT, the dynamic symbol table and other dynamic sections is
determined, which will depend on the number of symbols making it to the
dynamic symbol table. It is also appropriate to do the sweep at this
point as it is already after any changes have been made to symbols with
`bfd_elf_record_link_assignment', and not possible any earlier as calls
to that function are only made just beforehand -- barring audit entry
processing -- via `gld${EMULATION_NAME}_find_statement_assignment'

PowerPC dynamic relocations
This patch fixes a number of issues with powerpc dynamic relocations.
1) Both ppc and ppc64 were emitting more dynamic symbols and
relocations than necessary, due to not supporting static linker
resolution of tls_index entries for __tls_get_addr_opt. This meant
that any @got@tlsgd or @got@tlsld reloc needed to make their symbols
dynamic and generate dptmod and dtprel relocs for the dynamic linker.
That would have been passable, but what happened was that practically
all @got relocations resulted in their symbols being made dynamic and
dynamic relocations emitted against the GOT entries. (Mostly visible
on ppc32 executables since ppc64 gcc really only uses @got style
relocs for TLS.)
2) The PowerOpen syntax was not supported with __tls_get_addr_opt.
DTPMOD/DTPREL relocs on tls_index TOC entries did not use the trick of
forcing dynamic symbols and relocations so those entries always
resulted in the full __tls_get_addr processing. gcc doesn't use the
PowerOpen syntax for TLS, and normally such code would be optimized to
TLS IE or LE so the impact of missing this support was minimal.
3) In an executable, relocations against GNU indirect functions always
used the value of their PLT stub. While this is correct, it is
better in some cases to use a dynamic relocation. An extra dynamic
relocation can mean that calls via function pointers need not bounce
through the PLT stub at runtime.
The patch also tidies the PLT handling code in ppc32
allocate_dynrelocs. Allocating PLT entries after other dynamic relocs
allows the PLT loop to omit special handling for undefined weak
symbols, and that in turn allows the loop to be simplified.

Fix Py_DECREF being executed without holding the GIL
When the gdbpy_ref objects get destroyed, they call Py_DECREF to
decrement the reference counter of the python object they hold a
reference to. Any time we call into the Python API, we should be
holding the GIL. The gdbpy_enter object does that for us in an
RAII-fashion.
However, if gdbpy_enter is declared after a gdbpy_ref object in a
function, gdbpy_enter's destructor will be called (and the GIL will be
released) before gdbpy_ref's destructor is called. Therefore, we will
end up calling Py_DECREF without holding the GIL.
This became obvious with Python 3.6, where memory management functions
have asserts to make sure that the GIL is held. This was exposed by
tests py-as-string.exp, py-function.exp and py-xmethods. For example:
(gdb) p $_as_string(enum_valid)

Fix python-interactive with Python 3.6
New in v2:
- Define PyMem_RawMalloc as PyMem_Malloc for Python < 3.4 and use
PyMem_RawMalloc in the code.
Since Python 3.4, the callback installed in PyOS_ReadlineFunctionPointer
should return a value allocated with PyMem_RawMalloc instead of
PyMem_Malloc. The reason is that PyMem_Malloc must be called with the
Python Global Interpreter Lock (GIL) held, which is not the case in the
context where this function is called. PyMem_RawMalloc was introduced
for cases like this.
In Python 3.6, it looks like they added an assert to verify that
PyMem_Malloc was not called without the GIL. The consequence is that
typing anything in the python-interactive mode of gdb crashes the
process. The same behavior was observed with the official package on
Arch Linux as well as with a manual Python build on Ubuntu 14.04.
This is what is shown with a debug build of Python 3.6 (the error with a
non-debug build is far less clear):

Years ago we contributed flash programming patches upstream. The following
patch is a leftover one that complements that functionality by adding a new
command to erase all reported flash memory blocks.
The command is most useful when we're dealing with flash-enabled targets
(mostly bare-metal) and we need to reset the board for some reason.
The wiping out of flash memory regions should help the target come up with a
known clean state from which the user can load a new image and resume
debugging. It is convenient enough to do this from the debugger, and there is
also an MI command to expose this functionality to the IDE's.

objdump: Better objdump section headers in wide mode
When displaying the section headers table using objdump (-h), the column
containing the section header name is currently fixed at 13 characters.
A section name that is longer than 13 characters will overflow the
column causing the table to become miss-aligned.
In this commit I change the behaviour so that _in wide mode_ (-w -h) the
section name column is dynamically resized to fit the longest section
name we plan to display. In wide mode the column still retains a
minimum width of 13 characters.
In non-wide more the behaviour is completely unchanged.
While I was changing the dump_headers function I have unified the two
printf lines that handled the different address widths into a single
printf, the address width is now passed into printf using the '*' field
width format character.
binutils/ChangeLog:
* objdump.c (dump_section_header): Extract max section name length
from data parameter, use this when formatting output.
(find_longest_section_name): New function.
(dump_headers): Calculate longest section name when in wide mode,
reformat to unify printing of header line.

* testsuite/ld-elf/eh-frame-hdr.d: Update expected results.

PR ld/20828: Fix linker script symbols wrongly forced local with section GC
Fix a generic ELF linker regression introduced with a chain of changes
made to unused input section garbage collection:
- commit

references."),

6673f753c019 ("Fix PR 12772, garbage collection of dynamic
syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>,
causing the garbage collection of unused symbols present in a DSO
involved in a link to make identically named symbols ordinarily defined
(i.e. not hidden or PROVIDEd) by a linker script local, even though the
latter symbols are supposed to be global as if no DSO defined them as
well.
This is because linker script assignments are processed very late as
`lang_process' proceeds, down in the call to `ldemul_before_allocation',
which is made after the call to `lang_gc_sections' to do input section
garbage collecting. Consequently if unused, then any such DSO-defined
symbol has already been garbage-collected and internally marked local.
It would ordinarily be removed from dynamic symbol table output, however
a linker script assignment correctly replaces its original definition
with the new one and enters it into the dynamic symbol table produced as
it is supposed to be exported. The original local marking is however
retained making the symbol local in the dynamic symbol table and
therefore not available externally. This also causes a sorting problem
with the MIPS target, which does not expect non-section local dynamic
symbols to be output and produces an invalid binary.
Fix the problem then, by removing the `forced_local' marking for the
offending case and add suitable test cases. First to verify that unused
symbols ordinarily defined with linker script assignments remain
exported in the context of input section garbage collection whether or
not a DSO defining identically named symbols is present in the link.
Second that a linker version script still correctly retains or removes
such symbols as requested.

PR gas/20649: MIPS: Fix GOT16/LO16 reloc pairing with comdat sections
Correct a regression from commit
8614eeee67f9 ("Traditional MIPS
patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>,
which caused symbols in linkonce or what is these days known as comdat
sections to be treated as external for the purpose of PIC relocation
generation even if their binding remains STB_LOCAL. This in turn
disabled GOT16/LO16 relocation pairing with references to such symbols,
as no complementing LO16 relocation is expected for external GOT16
references in the o32 ABI, which ultimately leads to link errors, e.g.:
ld: comdat-reloc.o: Can't find matching LO16 reloc against `foo' for R_MIPS_GOT16 at 0x24 in section `.text.bar[bar]'
as with the LD test case included with this change.
Revert the special case for symbols in comdat sections then, making code
actually match `adjust_reloc_syms' as indicated in its explanatory
comment, and adjust calling code accordingly. Also bring back the
