The gdb.decode_line python function is documented to support the same location
expressions as the "break" command. It currently expects a linespec location.
Instead of creating a linespec location directly, create the location via
string_to_event_location_basic.

Most BFD linker functions take a bfd_link_info param, which reinforces
the fact that they are linker functions and allow access to linker
callbacks, eg. einfo for printing errors. I was going to use einfo
for --fatal-warnings support before I decided a better way was the
patch commit 4519d071.

This simple commit consolidates the API of
target_supports_multi_process. Since both GDB and gdbserver use the
same function prototype, all that was needed was to move create this
prototype on gdb/target/target.h and turn the macros declared on
gdb/{,gdbserver/}target.h into actual functions.
Regtested (clean pass) on the BuildBot.

Fixes this failure when building in C mode. I think it's relevant for master
as well, since it's a good practice to include (or forward-declare) what you
use.

This patch removes the Java support from gdb. gcj has not seen much
development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are
still users using gcj, they can continue to use an older gdb to debug.
Or, they can debug in C++ mode.
Built and regtested on x86-64 Fedora 24.

Fix a regression from commit f8b73d13b7ca ("Target-described register
support for MIPS"),
<https://sourceware.org/ml/gdb-patches/2007-05/msg00340.html>,
<https://sourceware.org/ml/gdb-patches/2007-06/msg00256.html>, which
caused Floating Point Control Registers (FCRs) to be shown as 64-bit
with 64-bit targets.
This came from the legacy register format where all raw registers
matched the width of the architecture regardless of their actual size.
The correct size was then set in `mips_register_type' for cooked
registers presented to the user, which in the case of FCRs meant the
cooked size was always forced to 32 bits, reflecting their actual
hardware size, even though the raw format carried them in 64-bit
quantities on 64-bit targets. The upper 32 bits carried in the raw FCR
format have always been don't-cares, not actually retrieved from
hardware and never written back.
With the introduction of XML register descriptions the layout of
previously defined raw registers has been preserved, so as to keep
existing register handling code unchanged and make it easier for GDB and
`gdbserver' to interact with each other whether neither, either or both
parties talking over RSP support XML register descriptions. For the
XML-described case however `mips_register_type' is not used in raw to
cooked register conversion, so any special cases coded there are not
taken into account.
Instead a new function, `mips_pseudo_register_type', has been introduced
to handle size conversion, however lacking the special case for FCRs for
the Linux and the now defunct IRIX target. The correct size has been
maintained for embedded targets however, due to the bundling of FCRs
with the embedded registers under the `rawnum >= MIPS_EMBED_FP0_REGNUM +
32' condition.
Add the missing case to `mips_pseudo_register_type' then, referring to
the FCR indices explicitly, and observing that between
`MIPS_EMBED_FP0_REGNUM + 32' and `MIPS_FIRST_EMBED_REGNUM' there is an
unused register slot whose contents are ignored so with the removal of
embedded FCRs from under that condition we don't have to care about it
and we can refer to the embedded registers starting from
MIPS_FIRST_EMBED_REGNUM instead.
Add a test case too so that we have means to check automatically that
the correct user-visible size of FCRs is maintained.

Even though this was supposedly in the gdb 7.2 timeframe, the testcase

This is GDB trying to print the location spec of the JIT event
breakpoint, but that's an internal breakpoint without one.
If I add a NULL check, then we see that the JIT breakpoint is now
pending (because its location has shlib_disabled set):
(gdb) maint info breakpoints
Num Type Disp Enb Address What
[...]
-8 jit events keep y <PENDING> inf 1
[...]
But that's incorrect. GDB should have managed to recreate the JIT
breakpoint's location for the second run. So the problem is
elsewhere.
The problem is that if the JIT loads at the same address on the second
run, we never recreate the JIT breakpoint, because we hit this early
return:
static int
jit_breakpoint_re_set_internal (struct gdbarch *gdbarch,
struct jit_program_space_data *ps_data)
{
[...]
if (ps_data->cached_code_address == addr)
return 0;
[...]
delete_breakpoint (ps_data->jit_breakpoint);
[...]
ps_data->jit_breakpoint = create_jit_event_breakpoint (gdbarch, addr);
Fix this by deleting the breakpoint and discarding the cached code
address when the objfile where the previous JIT breakpoint was found
is deleted/unloaded in the first place.
The test that was originally added for PR11094 doesn't trip on this
because:
#1 - It doesn't test the case of the JIT descriptor's address _not_
changing between reruns.
#2 - And then it doesn't do "maint info breakpoints", or really
anything with the JIT at all.
#3 - and even then, to trigger the problem the JIT descriptor needs
to be in a separate library, while the current test puts it in
the main program.
The patch extends the test to cover all combinations of these
scenarios.

I noticed that we sometimes get this:
(gdb) print &__jit_debug_descriptor
$1 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
[...]
(gdb) run
[...]
Starting program: build/gdb/testsuite/outputs/gdb.base/jit-simple/jit-simple
Unsupported JIT protocol version 4 in descriptor (expected 1)
Breakpoint 2, main () at src/gdb/testsuite/gdb.base/jit-simple.c:36
36 return 0;
(gdb) print &__jit_debug_descriptor
$2 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
All tests PASSed, but note the "Unsupported JIT protocol version 4"
message.
Also notice that "__jit_debug_descriptor" has the same address before
and after the rerun, while the test is built in a way that should make
that address change between runs.
The test doesn't catch any of this because it doesn't compare
before/after addresses.
And then notice the "blah 1" test messages. "blah" is clearly a WIP
message, but it should be at least "blah 2" the second time. :-)
The reason this sometimes happens is that the test recompiles the
program and expects gdb to reload it automaticallyt on "run". However,
if the original program and the new recompilation happen to be in the
same second, then gdb does not realize that the binary needs to be
reloaded. (This is an old problem out of scope of this series.) If
that happens, then GDB ends up using the wrong symbols for the program

Fix that in the same way gdb.base/reread.exp handles it -- by sleeping
one second before recompiling.

The .cfi_sections directive can be safely used multiple times
with different sections named at any time unless the compact form
of exception handling is requested after CFI information has
been emitted. Only the compact form of CFI information changes
the way in which CFI is generated and therefore cannot be
retrospectively requested after generating CFI information.

The .exp patch is an obvious typo fix I think. The regex was written to
accept "ADDR in main" and I find it OK as checking .debug_line validity is not
the purpose of this testfile.
gcc-4.8.5-11.el7.x86_64 did not put the 'mov $0x0,%eax' instruction there at
all so there was no problem with .debug_line.

In DWARF expression handling, some operators are required to be either
at the end of an expression or followed by a composition operator. So
far only the operators DW_OP_reg0-31 were allowed to be followed by
DW_OP_GNU_uninit instead, and particularly DW_OP_regx was not, which is
obviously inconsistent.
This patch allows DW_OP_GNU_uninit after all operators requiring a
composition, to simplify the code and make it more consistent. This
policy may be more permissive than necessary, but in the worst case just
leads to a DWARF location description resulting in an uninitialized
value instead of an error message.
gdb/ChangeLog:
* dwarf2expr.c (dwarf_expr_require_composition): Allow
DW_OP_GNU_uninit.
(execute_stack_op): Use dwarf_expr_require_composition instead of
copying its logic.

The logging message is called too often - once for each register when it's
value has to be evaluated. This floods the screen for commands like "info
register all", but doesn't give really any help at debugging GDB issues.
Between increasing the debug level of this message and removing it altogether I
think that removing it is preferable.

Nowadays, there are a lot of duplication about
i386/{i386, amd64, x32}*-expedite in features/Makefile. However,
in features/Makefile, we have
echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
>> $(outdir)/$*.tmp
which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite. In x86 expedite registers, we
use the former now, but it will be much simpler if we use the latter.
This is what this patch does. This patch removes them, and defines
three generic expedite. Re-run 'make GDB=/path/build/gdb all' to
regenerate regformats/*.dat files, and they are not changed.
