Revise "ld testsuite use of notarget"
git commit
624940689a wrongly changed fill.d and fill16.d notarget
entries to xfail, so revert that change and instead replace notarget
with skip. The two tests are complementary.
This patch also modifies the pr20022 test to use .data, avoiding
xfails on targets that complain about dynamic relocations in .text.
This shows a bug in metag which discards section _foo in pr2022.so.

xgate cleanup
elf32-xgate.c contains many functions that are only stubs and
elf32-xgate.h contains unused declarations. While this might be
reasonable for the initial commit of a port with subsequent work
fleshing out the stubs, xgate has only had two minor target specific
patches since the initial commit over six years ago. The rest of the
changes have been general maintenance work applied to all ELF targets,
and some of this work could have been avoided if the stubs hadn't been
there. So this patch removes all the stubs.
I've kept the functionality of the old elf32_xgate_add_symbol_hook,
implemented in elf32_xgate_backend_symbol_processing. Presumably,
that's to set the symbol st_target_internal flag for use in
elf32-m68hc1x.c:elf32_m68hc11_relocate_section.
The empty elf32_xgate_relocate_section meant that xgate had no linker.
Or at least, no linker relocation processing. Deleting the
elf_backend_relocate_section define means the target will now use the
generic linker reloc processing. How good that is will depend on the
accuracy of the reloc howtos..
I haven't updated the ld testsuite to xfail tests expected to fail
for generic elf targets.

2) Tests might be used as a template for a new test, carrying over

gdb/testsuite: Allow for failure to read some memory addresses
In the gdb.base/examine-backward.exp test script, we check to see if
address zero is readable, and then read memory first forward from
address zero, and then backward from address zero.
The problem is, being able to read address zero does not guarantee
that you'll be able to read from the other end of the address space,
and the test probably shouldn't assume that is the case.
This patch updates the test script so that even if address zero is
known non-readable, we still run the tests, the tests in question are
mostly about, can GDB calculate the correct address to read from, we
can confirm this even if the final read ultimately fails. We also no
longer assume that if address zero is readable, then the other end of
the address space will be readable.
One further change is that, when we examined the memory at address
zero, the regexp used to match the address expected that the zero
address would have two '0' digits as the least significant digits. As
GDB strips leading zeros from addresses this was causing the test to
fail. I've reduced the zero address to a single 0 digit.
gdb/testsuite/ChangeLog:
* gdb.base/examine-backward.exp: Still run tests around address
0x0, even if address 0x0 is not readable. Update the pattern for
matching address 0x0 in expected output.

darwin: Don't use sbrk
This patch gets rid of this warning on macOS:
CXX main.o
/Users/simark/src/binutils-gdb/gdb/main.c:492:27: error: 'sbrk' is deprecated [-Werror,-Wdeprecated-declarations]
lim_at_start = (char *) sbrk (0);
^
/usr/include/unistd.h:585:1: note: 'sbrk' has been explicitly marked deprecated here
__deprecated __WATCHOS_PROHIBITED __TVOS_PROHIBITED
^
/usr/include/sys/cdefs.h:176:37: note: expanded from macro '__deprecated'
#define __deprecated __attribute__((deprecated))
^
sbrk on macOS is not useful for our purposes, since sbrk(0) always
returns the same value. From what I read, brk/sbrk on macOS is just an
emulation, it always returns a pointer in a 4MB section reserved for
that.
So instead of letting users use "maint set per-command space on" and
print silly results, I think we should just disable that feature for
this platform (as we do for platforms that don't have sbrk).
I defined a HAVE_USEFUL_SBRK macro and used that instead of HAVE_SBRK.

Warn if /proc is not accessible
There's a buildroot where I want to debug a binary, and I tried to
connect to it from outside, but got very weird errors like
architecture mismatch or protocol errors. At last, after switching on
'--debug' for gdbserver I found a message 'Can't open /proc/pid/'
message and suddenly found that I forgot to mount procfs in my
buildroot.
Make discovering the problem easier by making GDB / GDBserver warn
(even without --debug) if /proc can not be accessed.

Remove exit_inferior_num_silent
The sole caller of exit_inferior_num_silent was getting the inferior's
number to then use the number to look up the inferior again. I think
it's better to simply not have exit_inferior_num_silent; any potential
callers that only have the inferior's number should probably be
converted to pass the inferior itself around instead.

Fix crash in "run" on macOS when gdb is not signed
On macOS, when gdb is not code-signed, it will throw an exception from
darwin_attach_pid. However, gdb also then crashes:
thread.c:93: internal-error: struct thread_info *inferior_thread(): Assertion `tp' failed.
I think the problem here is that darwin_attach_pid does not clean up
inferior_ptid and inf->pid on failure. This leads to a situation
where gdb tries to find a thread, but cannot.
In other cases, gdb would mourn the inferior at this point; but here
this is not possible because the target has not been pushed. Instead
this patch works by simply updating the inferior and inferior_ptid on
failure.
Tested by building an unsigned gdb on macOS and trying to run an
inferior.

GNU attribute output on errors
.gnu.attributes entries from linker input files are merged to the
output file, the output having the union of compatible input
attributes. Incompatible attributes generally cause a linker error
and no output. However in some cases only a warning is emitted, and
one of the incompatible input attributes is passed on to the output.
PowerPC tends to emit warnings rather than errors, and the output
takes the first input attribute. For example, if we have two input
files with Tag_GNU_Power_ABI_FP, the first with a value signifying
"double-precision hard float, IBM long double", the second with a
value signifying "double-precision hard float, IEEE long double",
we'll get a warning about incompatible long double types and the
output will say "double-precision hard float, IBM long double".
The output attribute of course isn't correct. It would be correct to
specify "IBM and IEEE long double", but we don't have a way to
represent that currently. While it would be possible to extend the
encoding, there isn't much gain in doing so. A shared library
providing support for both long double types should link against
objects using either long double type without warning or error. That
is what you'd get if such a shared library had no Tag_GNU_Power_ABI_FP
attribute.
So this patch provides a way for the backend to omit .gnu.attributes
tags from the output.

GDB PR tdep/8282: MIPS: Wire in `set disassembler-options'
Implement MIPS target support for passing options to the disassembler,
complementing commit
65b48a81404c ("GDB: Add support for the new
set/show disassembler-options commands.").
This includes options that expect an argument, so adjust the generic
code and data structures used so as to handle such options. So as to
give backends syntax flexibility no specific delimiter has been defined
to separate options from their respective arguments, so it has to be
included as the last character of the option name. Completion code
however has not been adjusted and consequently option arguments cannot
be completed at this time.
Also the MIPS target has non-empty defaults for the options, so that ABI
names for the general-purpose registers respect our `set mips abi ...'
setting rather than always being determined from the ELF headers of the
binary file selected. Handle these defaults as implicit options, never
shown to the user and always prepended to the user-specified options, so
that the latters can override the defaults.
The resulting output for the MIPS target is as follows:
(gdb) show disassembler-options
The current disassembler options are ''
The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:
no-aliases Use canonical instruction forms.
msa Recognize MSA instructions.
virt Recognize the virtualization ASE instructions.

instructions.

Existing affected target backends have been adjusted accordingly.
This has been verified manually with:
(gdb) set architecture arm
(gdb) set architecture powerpc:common
(gdb) set architecture s390:31-bit
to cause no issues with the `show disassembler-options' and `set
disassembler-options' commands. A test case for the MIPS target has
also been provided, covering the default settings with ABI overrides as
well as disassembler option overrides.

Allow BFD to recognize macOS universal libraries
Bug #13157 is about a gdb regression, where previously it could handle
universal libraries, but now cannot.
gdb isn't working for me on macOS for other reasons, so I wrote this
small test program to show the problem:
#include <config.h>
#include <stdio.h>
#include <stdlib.h>
#include <bfd.h>
void
die (const char *what)
{
fprintf (stderr, "die: %s\n", what);
exit (1);
}
int
main (int argc, char **argv)
{
bfd *file = bfd_openr (argv[1], NULL);
if (file == NULL)
die ("couldn't open");
if (!bfd_check_format (file, bfd_archive))
die ("not an archive");
printf ("yay\n");
bfd_close (file);
return 0;
}
Then I built a simple universal binary. With git master BFD, I get:
$ ./doit ./universal-exe
die: not an archive
Jeff Muizelaar tracked this down to the BFD change for PR binutils/21787.
This patch changed bfd_generic_archive_p to sometimes reset the BFD's
"format" field.
However, simply changing bfd_generic_archive_p regressed the test case
in that bug.
Debugging PR binutils/21787 again, what I saw is that the mach-o
universal binary support acts like a bfd_archive but does not provide
a _close_and_cleanup function. However, if a BFD appears as an
archive member, it must always remove its own entry from its parent's
map. Otherwise, when the parent is destroyed, the already-destroyed
child BFD will be referenced. mach-o does not use the usual archive
member support, so simply using _bfd_archive_close_and_cleanup (as
other targets do) will not work.
This patch fixes the problem by introducing a new
_bfd_unlink_from_archive_parent function, then arranging for it to be
called in the mach-o case.
Ok?

[ARM] Update bfd's Tag_CPU_arch knowledge
BFD's bfd_get_mach () function returns a bfd specific value representing
the architecture of the target which is populated from the Tag_CPU_arch
build attribute value of that target. Among other users of that
interfacem, objdump which uses it to print the architecture version of
the binary being examinated and to decide what instruction is available
if run with "-m arm" via its own mapping from bfd_mach_arm_X values to
feature bits available.
However, both BFD and objdump's most recent known architecture is
Armv5TE. When encountering a newer architecture bfd_get_mach will return
bfd_mach_arm_unknown. This is unfortunate since objdump uses that value
to allow all instructions on all architectures which is already what it
does by default, making the "-m arm" trick useless.
This patch updates BFD and objdump's knowledge of Arm architecture
versions up to the latest Armv8-M Baseline and Mainline, Armv8-R and
Armv8.4-A architectures. Since several architecture versions (eg. 8.X-A)
share the same Tag_CPU_arch build attribute value and
bfd_mach_arm values, the mapping from bfd machine value to feature bits
need to return the most featureful feature bits that would yield the
given bfd machine value otherwise some instruction would not disassemble
under "-m arm" mode. The patch rework that mapping to make this clearer
and simplify writing the mapping rules. In particular, for simplicity
all FPU instructions are allowed in all cases.
Finally, the patch also rewrite the cpu_arch_ver table in GAS to use the
TAG_CPU_ARCH_X macros rather than hardcode their value.

Fix use of "command line X" in binutils doc
Binutils documentation uses a mix of spelling for the compound word
"command-line X". According to [1]:
"Sometimes compound words are written separately (nail polish),
sometimes with a hyphen (short-sighted) and sometimes as one word
(eyelashes). Often new compounds are written as two separate words and,
as they become more familiar, they are either connected with a hyphen
(-) or made into one word."
I think command-line X is common enough in our industry that the two
workds command and line should be connected. Since command-line is more
common than commandline, I propose to update binutils documentation to
consistently use "command-line" when this is used as an adjective to a
noun (eg. command-line argument, command-line switch, command-line
option and command-line flag). I've left occurences of "the command
line" as is. I've also left gdb, sim and readline alone and have only
touched public documentation (texi and NEWS files).
