Since UNDEFINED_WEAK_RESOLVED_TO_ZERO has been added to elf-bfd.h, the
private copy of UNDEFINED_WEAK_RESOLVED_TO_ZERO can be removed from
elfxx-sparc.c. Also replace has_got_reloc and has_non_got_reloc with
zero_undefweak in elf_link_hash_entry:
Bit 0: Symbol has no GOT nor PLT relocations.
Bit 1: Symbol has non-GOT/non-PLT relocations in text sections.
zero_undefweak is initialized to 1 and undefined weak symbol should be
resolved to 0 if zero_undefweak > 0.

For all ELF targers, call check_relocs after opening all inputs and
garbage collection. Since the symbol resolution is known, check_relocs
can be simplified. Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.
Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.
ldemul_after_check_relocs is added for powerpc to support --secure-plt,
--bss-plt and --sdata-got.
Tested natively without regressions on i686, x86-64 and x32. Tested

Support for collecting and supplying general purpose and floating
point registers is provided along with signal frame unwinding. While
FreeBSD/arm kernels do populate NT_FPREGSET notes, they are always
zero-filled, so this implementation ignores them. Recent FreeBSD/arm
kernels generate NT_ARM_VFP notes which are used to supply
floating-point registers. As with Linux, the AT_HWCAP feature flags
are used to determine the correct target description.

Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO
notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>,
and handle both variants of the 64-bit Linux core PRPSINFO note across
all targets.
The 64-bit Linux core PRPSINFO note matches the 64-bit kernel structure,
defined as follows:
(gdb) ptype struct elf_prpsinfo
type = struct elf_prpsinfo {
char pr_state;
char pr_sname;
char pr_zomb;
char pr_nice;
unsigned long pr_flag;
__kernel_uid_t pr_uid;
__kernel_gid_t pr_gid;
pid_t pr_pid;
pid_t pr_ppid;
pid_t pr_pgrp;
pid_t pr_sid;
char pr_fname[16];
char pr_psargs[80];
}
(gdb)
where the individual data types of most members are the same across all
64-bit Linux ports, with the exception of `__kernel_uid_t' and
`__kernel_gid_t'. These are defined in <asm-generic/posix_types.h> as
32-bit `unsigned int' by default, however overridden as 16-bit `unsigned
short' in port-specific <asm/posix_types.h> for the SuperH target.
The default is already handled, as from the commit referred. Add the
other variant then and provide a backend flag to switch between the two
cases possible, with the 32-bit one being the default and the 16-bit one
explicitly selected. Set the flag in the SuperH target backend. This
arrangement is analogous to how the 32-bit Linux core PRPSINFO note is
handled.

Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO

and commit b3ac9c77560a ("Put more info in NT_PRPSINFO Linux notes"),
<https://sourceware.org/ml/binutils/2013-02/msg00024.html>, and handle
both variants of the 32-bit Linux core PRPSINFO note across all targets.
The 32-bit Linux core PRPSINFO note matches the 32-bit kernel structure,
defined as follows:
(gdb) ptype struct elf_prpsinfo
type = struct elf_prpsinfo {
char pr_state;
char pr_sname;
char pr_zomb;
char pr_nice;
unsigned long pr_flag;
__kernel_uid_t pr_uid;

pid_t pr_pid;
pid_t pr_ppid;
pid_t pr_pgrp;
pid_t pr_sid;
char pr_fname[16];
char pr_psargs[80];
}
(gdb)
where the individual data types of most members are the same across all
32-bit Linux ports, with the exception of `__kernel_uid_t' and
`__kernel_gid_t'. These are defined in <asm-generic/posix_types.h> as
32-bit `unsigned int' by default, however overridden as 16-bit `unsigned
short' in port-specific <asm/posix_types.h> for a few targets, mostly
earlier ports of Linux, specifically: ARM, CRIS, FR-V, M32R, m68k,
MN10300/AM33, s390, SuperH, SPARC and i386.
The default is the same as the PowerPC variant already handled, as from
the commits referred. Make the special PowerPC case generic then,
removing the GDB part, and provide a backend flag to switch between the
two cases possible, with the 32-bit one being the default and the 16-bit
one explicitly selected. Set the flag in the target backends affected.

Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO
notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>,
and move the padding of the `elf_external_linux_prpsinfo64' structure to
match the corresponding 64-bit Linux kernel `elf_prpsinfo' structure.
The 64-bit kernel structure is defined as follows:
(gdb) ptype struct elf_prpsinfo
type = struct elf_prpsinfo {
char pr_state;
char pr_sname;
char pr_zomb;
char pr_nice;
unsigned long pr_flag;
__kernel_uid_t pr_uid;
__kernel_gid_t pr_gid;
pid_t pr_pid;
pid_t pr_ppid;
pid_t pr_pgrp;
pid_t pr_sid;
char pr_fname[16];
char pr_psargs[80];
}
(gdb) print /x &((struct elf_prpsinfo *)0)->pr_nice
$1 = 0x3
(gdb) print /x &((struct elf_prpsinfo *)0)->pr_flag
$2 = 0x8
(gdb) print /x &((struct elf_prpsinfo *)0)->pr_uid
$3 = 0x10
(gdb) print sizeof(((struct elf_prpsinfo *)0)->pr_flag)
$4 = 8
(gdb)
with implicit padding present before the `pr_flag' member, to correctly
align it to a multiple of 8. Conversely `elf_external_linux_prpsinfo64'
has padding after its `pr_flag' member:
(top-gdb) ptype struct elf_external_linux_prpsinfo64
type = struct elf_external_linux_prpsinfo64 {
char pr_state;
char pr_sname;
char pr_zomb;
char pr_nice;
char pr_flag[8];
char gap[4];
char pr_uid[4];
char pr_gid[4];
char pr_pid[4];
char pr_ppid[4];
char pr_pgrp[4];
char pr_sid[4];
char pr_fname[16];
char pr_psargs[80];
}
(top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_nice
$1 = 0x3
(top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_flag
$2 = 0x4
(top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_uid
$3 = 0x10
(top-gdb)
and consequently `pr_flag' is misplaced. Move `gap' ahead of `pr_flag'
then.
bfd/
* elf-linux-core.h (elf_external_linux_prpsinfo64): Move the
`gap' member ahead of `pr_flag'.

There was a problem with generation of the disassembler options for ARC in GDB,
because a BFD architecture name was used as a CPU name, but they have different
meaning even if some architectures have same name as respective CPUs. Target
description specifies a BFD architecture, which is different from ARC CPU, as
accepted by the disassembler (and most other ARC tools), because CPU values are
much more fine grained - there can be multiple CPU values per single BFD
architecture. As a result this code should translate architecture to some CPU
value. Since there is no info on exact CPU configuration, it is best to use
the most feature-rich CPU, so that the disassembler will recognize all
instructions available to the specified architecture.

(This patch is from Mark Rages <markrages@gmail.com>.)
The Nordic nRF52 memory map, reported from black magic probe:
Num Enb Low Addr High Addr Attrs
0 y 0x00000000 0x00080000 flash blocksize 0x1000 nocache
1 y 0x10001000 0x10001210 flash blocksize 0x210 nocache
2 y 0x20000000 0x20010000 rw nocache
The region at 0x10001000 is "UICR" and it is a section of flash that is
erased all at once.
Notice the odd size: 0x210 is the size of the region defined in the
datasheet.
But because the block size was listed as 0x210, gdb was insisting on
issuing two erase commands divisible by 0x210, starting below 0x10001000.
This patch fixes it by doing the alignment computation from the start of
the region, not from address 0.
gdb/ChangeLog:
* target-memory.c (block_boundaries): Fix for block address not
aligned on block size.

Since x86 check_relocs is called after opening all inputs and garbage
collection, they never see the removed sections. There is no need
for incrementing GOT refcount. But since PLT refcount is also used in

relocations which can be resolved at run-time. */
else if (htab->elf.dynamic_sections_created

The get_integer_valueof outputs the value it has read as part of the
test name. This causes test names to vary from run to run, and adds
some noise when diffing test results. e.g.:
-PASS: gdb.threads/process-dies-while-detaching.exp: multi-process: continue: killed outside: get integer valueof "mypid" (28770)
+PASS: gdb.threads/process-dies-while-detaching.exp: multi-process: continue: killed outside: get integer valueof "mypid" (32238)
This patch removes that, since it's probably not very useful.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (get_integer_valueof): Don't output read value in test name.

I was recently examining a very large .debug file. I tried to use
dwarf-mode, but it blocked Emacs for a very long time while reading
output.
This patch changes dwarf-mode to run the objdump process asynchronously.
This way, I can still do other things in Emacs while waiting for the
dumping to finish.

defvar.

It's bad Emacs style to define keys from a top-level form. Instead, one
should define a mode map separately and binding keys in the definition.
This lets users completely override the map by defining it before
loading the mode.

* dwarf-mode.el (dwarf-mode-map): New defvar.

This patch gets rid of catch_exceptions / catch_exceptions_with_msg.
The latter is done mostly by getting rid of the three remaining
vestigial libgdb wrapper functions, which are really pointless
nowadays. This results in a good number of simplifications.
(I checked that Insight doesn't use those functions.)
The gdb.mi/mi-pthreads.exp change is necessary because this actually
fixes a bug, IMO -- the patch stops MI's -thread-select causing output
on the CLI stream.
I.e., before:
-thread-select 123456789
&"Thread ID 123456789 not known.\n"
^error,msg="Thread ID 123456789 not known."
(gdb)
After:
-thread-select 123456789
^error,msg="Thread ID 123456789 not known."
(gdb)

If you want to use catch_errors with a function with parameters, then
currently you have to manually write a "capture" struct wrapping the
arguments and marshall/unmarshall that.
https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed
adjusting catch_errors to use gdb::function_view, which would allow
passing lambdas with automatic captures. However, it seems like using
TRY/CATCH directly instead ends up producing clearer and easier to
debug code. This is what this commit does.
Note that removing catch_errors exposes further cleanup opportunities
around no longer having to follow catch_errors callback type, and also
removes a few cleanups.
I didn't do anything to save/restore current_uiout because I think
that should be the responsibility of the code that changes
current_uiout in the first place.
(Another approach could be to make catch_errors a variadic template
like:
template<typename Function, typename... Args>
int catch_errors (const char *errstring, return_mask mask,
Function &&func, Args... args);
and then with:
extern void function_with_args (int, int);
extern void function_with_no_args ();
calls to the above functions would be wrapped like this:
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_args, arg1, arg2);
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_no_args);
but I'm thinking that that doesn't improve much if at all either.)
