Frank Ch. Eigler 404f29021a [PR build/24886] disable glibc mcheck support
This patch drops gdb's configury support for glibc's mcheck function.
It has been observed to cause false abort()s, because it is
thread-unsafe yet interposes every malloc/free operation.  So if any
library transitively used by gdb also uses threads, then these
functions can easily corrupt their own checking data.  These days, gcc
ASAN and valgrind provide high quality checking, and mcheck is
apparently itself being slowly deprecated.

So, let's stop linking to it.  Attached patch drops the
autoconf/Makefile machinery for both gdb and gdbserver.  No
testsuite-visible impact.  IMHO not worth mentioning in NEWS.

Tom Tromey 046bebe1c0 Add more styling to "disassemble"
This adds more styling to the disassemble command.  In particular,
addresses and function names in the disassembly are now styled.

This required fixing a small latent bug in set_output_style.  This
function always passed NULL to emit_style_escape; but when writing to
a file other than gdb_stdout, it should emit the style escape
directly.  (FWIW this is another argument for better integrating the
pager with ui_file and getting rid of this entire layer.)

Tom Tromey b08b16c839 Clean up source file error reporting
print_source_lines_base reopens the source file every time that a
source line is to be printed.  However, there's no need to do this so
frequently -- it's enough to do it when switching source files, and
otherwise rely on the cache.

The code seems to try to avoid these multiple opens; at a guess I'd
say something just got confused along the way.

This patch fixes the problem by reorganizing the code both to make it
more clear, and to ensure that reopens only occur when the "last
source visited" changes.

Tom Tromey cb44333d99 Add file offsets to the source cache
Currently, gdb stores the number of lines and an array of file offsets
for the start of each line in struct symtab.  This patch moves this
information to the source cache.  This has two benefits.

First, it allows gdb to read a source file less frequently.
Currently, a source file may be read multiple times: once when
computing the file offsets, once when highlighting, and then pieces
may be read again while printing source lines.  With this change, the
file is read once for its source text and file offsets; and then
perhaps read again if it is evicted from the cache.

Second, if multiple symtabs cover the same source file, then this will
share the file offsets between them.  I'm not sure whether this
happens in practice.

Tom Tromey 872dceaaff Save plain text in the source cache
Currently the source cache will only store highlighted text.  However,
there's no reason it could not also store plain text, when styling is

Tom Tromey 269249d940 Fix latent bug in source cache
The source cache was not returning the final \n of the requested range
of lines.  This caused regressions with later patches in this series,
so this patch pre-emptively fixes the bug.

This adds a self-test of "extract_lines" to the source cache code.  To
make it simpler to test, I changed extract_lines to be a static
function, and changed it's API a bit.

Alan Modra 128bf1fe60 LTO object insertion point
This is a mostly cosmetic fix for cases like PR24873 where LTO
recompiled objects were supposed to be inserted inside a group.  The
specific case handled by this patch is when the first file inside a
group is an archive, the first file claimed by the plugin.  Prior to
this patch we would have inserted the recompiled objects before the
group, which doesn't matter really since the entire group will be
reloaded, but it looks a little wrong in map files.

	* ldlang.c (find_replacements_insert_point): Return "before" flag.
	(find_next_input_statement): New function.

Alan Modra b02c4f1623 PR24873, gcc -flto objects result in --start-group .. --end-group failure to include --as-needed libraries
Reloading of archives (and checking --as-needed DSOs again) is
disabled until we hit the plugin insert point.  It's necessary to do
that because in a case like lib1.a lto.o lib2.a where lib1.a and
lib2.a contain duplicate symbols, we want the lto.o recompiled object
to pull in objects from lib2.a as necessary, but not from lib1.a.
Unfortunately this heuristic fails when the insert point is inside a
group, because ld actually loads the symbols from the recompiled
object before running over the contours of the script, thus missing
the fact that new undefs appeared in the group.

Simon Marchi 580f1034d1 Increase timeout in gdb.mi/list-thread-groups-available.exp
Running

    make check-read1 TESTS="gdb.mi/list-thread-groups-available.exp"

on my machine results in timeout failures.  Running it while having
`tail -F testsuite/gdb.log` on the side shows that the test is never
really blocked, it is just slow at consuming the large output generated
by `-list-thread-groups --available` (which lists all the processes on
the system).

If I increase the timeout to a large value, the test passes in ~30
seconds (compared to under 1 second normally).

Increase the timeout for the particular mi_gdb_test that is long to
execute under read1.  The new timeout value is a bit arbitrary.  The
default timeout is 10 seconds, so I set the new timeout to be
"old-timeout * 10", so 100 seconds in the typical case.

Tom Tromey 8abfcabcb4 Use _() in calls to build_help
Currently some code in gdb uses build_help with N_(), like:

  static const std::string compile_print_help
    = gdb::option::build_help (N_("\

I believe this is incorrect.  The N_ macro is used to mark text that
should end up in the message catalog, but which will be translated by
a later call to gettext.

However, in this case, there is no later call to gettext, so (if gdb
had translations), this text would remain untranslated.

Instead, I think using the ordinary _() macro is correct here.
Translators will have to know to preserve "%OPTIONS%" in the text --
but that seems both unavoidable and fine.

Tested by rebuilding as there's not much else to do.

Tom de Vries a80cf5d88e [gdb/testsuite] Fail in gdb_compile if pie results in non-PIE executable
When running gdb.base/break-idempotent.exp with
--target_board=unix/-fno-PIE/-no-pie, we get:
...

...

The test-case is compiled once with nopie and once with pie, but in both cases
we end up with a non-PIE executable.  The "-fno-PIE -no-pie" options specified
using the target_board are interpreted by dejagnu as multilib_flags, and end up
overriding the pie flags.

Fix this by checking in gdb_compile if the resulting exec is non-PIE despite of
a pie setting, and if so return an error:
...

Alexandre Oliva ca683e3a86 support Ada EH ABI v1
A new pair of hooks used by Ada exception handlers, for correct
release of reraised exception occurrences, involves the introduction
of new v1 symbols that GDB should use when available.  The older, v0
ABI remains available in newer runtimes for bootstrapping purposes
only.

Alan Modra 6a010cf67a [GOLD] PowerPC relocation signed overflow check
Relocations with right shifts were calculating wrong overflow status.
Since the addr34 split-field reloc is implemented as an 18-bit high
part with value shifted right by 16 and a 16-bit low part, most of the
pc-relative relocs were affected.

	* powerpc.cc (Powerpc_relocate_functions::rela, rela_ua): Perform
	signed right shift for signed overflow check.

Max Filippov e0d0c518da xtensa: bfd: add special case to loop alignment check
check_loop_aligned is used during link time relaxation to only allow
transformations that don't violate loop body alignment requirements.
Assembler can relax loops that have too long body by adding instructions
between the loop instruction and the loop body. check_loop_aligned must
check alignment of the first instruction of the actual loop body.
Detect loop / rsr.lend / wsr.lbeg sequence used in assembly time
relaxation and adjust alignment check when it's detected.

	and insn_len for the first actual instruction of the loop.

Christian Biesinger 0a7b24850e Include s12z-opc.h using ../opcodes.
This file exists in binutils-gdb/opcodes, and nothing in Makefile.in adds this
to the include path.  Default builds work because in-tree readline adds
binutils-gdb/ to the include path (!). However, this is broken when compiling
with system readline.

Other files already use this way to include files in opcodes:
./gdb/lm32-tdep.c:#include "../opcodes/lm32-desc.h"
./gdb/or1k-tdep.h:#include "../opcodes/or1k-desc.h"
./gdb/mep-tdep.c:#include "../opcodes/mep-desc.h"

etc.

Alan Hayward c6bdbeb7c4 Require GNU make 3.82
Gdbserver has failed to build with GNU make 3.81 since commit 08f10e02be.

Update the NEWS file to state that versions earlier than 3.82 are not
supported.

3.82 was released in 2010, 3.81 was released 2006. A quick investigation
of the default GNU make version provided across various distros found the
earliest provided version to be 3.82:
*RHEL 7, Centos 6 - make 3.82
*Fedora 27 - make 4.2.1
*OpenSuse 42.2, SLES11 - make 4.2.1
*Ubuntu 16.04/18.04 - make 4.1
*Debian Jessie - make 4.0

Note that Glibc requires at least 4.0, whereas GCC still allows 3.81.

	* NEWS: Require GNU make 3.82.

Alan Modra 776ab89fe3 PR24806, Linking with -T inside --start-group/--end-group
This patch processes INSERT AFTER and INSERT BEFORE in a user -T

forgot --end-group.

	PR 24806
