My obvious fix is just to skip the fixup for base types larger than a

Add a test that replicates this situation, but uses bounds that fit in a

GDB: Add a character string limiting option
This commit splits the `set/show print elements' option into two. We
retain `set/show print elements' for controlling how many elements of an
array we print, but a new `set/show print characters' setting is added
which is used for controlling how many characters of a string are
printed.
The motivation behind this change is to allow users a finer level of
control over how data is printed, reflecting that, although strings can
be thought of as arrays of characters, users often want to treat these
two things differently.
For compatibility reasons by default the `set/show print characters'
option is set to `elements', which makes the limit for character strings
follow the setting of the `set/show print elements' option, as it used
to. Using `set print characters' with any other value makes the limit
independent from the `set/show print elements' setting, however it can
be restored to the default with the `set print characters elements'
command at any time.
A corresponding `-characters' option for the `print' command is added,
with the same semantics, i.e. one can use `elements' to make a given
`print' invocation follow the limit of elements, be it set with the
`-elements' option also given with the same invocation or taken from the
`set/show print elements' setting, for characters as well regardless of
the current setting of the `set/show print characters' option.
The GDB changes are all pretty straightforward, just changing references
to the old 'print_max' to use a new `get_print_max_chars' helper which
figures out which of the two of `print_max' and `print_max_chars' values
to use.
Likewise, the documentation is just updated to reference the new setting
where appropriate.
To make people's life easier the message shown by `show print elements'
now indicates if the setting also applies to character strings:
(gdb) set print characters elements
(gdb) show print elements
Limit on string chars or array elements to print is 200.
(gdb) set print characters unlimited
(gdb) show print elements
Limit on array elements to print is 200.
(gdb)
and the help text shows the dependency as well:
(gdb) help set print elements
Set limit on array elements to print.
"unlimited" causes there to be no limit.
This setting also applies to string chars when "print characters"
is set to "elements".
(gdb)
In the testsuite there are two minor updates, one to add `-characters'
to the list of completions now shown for the `print' command, and a bare
minimum pair of checks for the right handling of `set print characters'
and `show print characters', copied from the corresponding checks for
`set print elements' and `show print elements' respectively.

GDB: Allow arbitrary keywords in integer set commands
Rather than just `unlimited' allow the integer set commands (or command
options) to define arbitrary keywords for the user to use, removing
hardcoded arrangements for the `unlimited' keyword.
Remove the confusingly named `var_zinteger', `var_zuinteger' and
`var_zuinteger_unlimited' `set'/`show' command variable types redefining
them in terms of `var_uinteger', `var_integer' and `var_pinteger', which
have the range of [0;UINT_MAX], [INT_MIN;INT_MAX], and [0;INT_MAX] each.
Following existing practice `var_pinteger' allows extra negative values
to be used, however unlike `var_zuinteger_unlimited' any number of such
values can be defined rather than just `-1'.
The "p" in `var_pinteger' stands for "positive", for the lack of a more
appropriate unambiguous letter, even though 0 obviously is not positive;
"n" would be confusing as to whether it stands for "non-negative" or
"negative".
Add a new structure, `literal_def', the entries of which define extra
keywords allowed for a command and numerical values they correspond to.
Those values are not verified against the basic range supported by the
underlying variable type, allowing extra values to be allowed outside
that range, which may or may not be individually made visible to the
user. An optional value translation is possible with the structure to
follow the existing practice for some commands where user-entered 0 is
internally translated to UINT_MAX or INT_MAX. Such translation can now
be arbitrary. Literals defined by this structure are automatically used
for completion as necessary.
So for example:
const literal_def integer_unlimited_literals[] =
{
{ "unlimited", INT_MAX, 0 },
{ nullptr }
};
defines an extra `unlimited' keyword and a user-visible 0 value, both of
which get translated to INT_MAX for the setting to be used with.
Similarly:
const literal_def zuinteger_unlimited_literals[] =
{
{ "unlimited", -1, -1 },
{ nullptr }
};
defines the same keyword and a corresponding user-visible -1 value that
is used for the requested setting. If the last member were omitted (or
set to `{}') here, then only the keyword would be allowed for the user
to enter and while -1 would still be used internally trying to enter it
as a part of a command would result in an "integer -1 out of range"
error.
Use said error message in all cases (citing the invalid value requested)
replacing "only -1 is allowed to set as unlimited" previously used for
`var_zuinteger_unlimited' settings only rather than propagating it to
`var_pinteger' type. It could only be used for the specific case where
a single extra `unlimited' keyword was defined standing for -1 and the
use of numeric equivalents is discouraged anyway as it is for historical
reasons only that they expose GDB internals, confusingly different
across variable types. Similarly update the "must be >= -1" Guile error
message.
Redefine Guile and Python parameter types in terms of the new variable
types and interpret extra keywords as Scheme keywords and Python strings
used to communicate corresponding parameter values. Do not add a new
PARAM_INTEGER Guile parameter type, however do handle the `var_integer'
variable type now, permitting existing parameters defined by GDB proper,
such as `listsize', to be accessed from Scheme code.
With these changes in place it should be trivial for a Scheme or Python
programmer to expand the syntax of the `make-parameter' command and the
`gdb.Parameter' class initializer to have arbitrary extra literals along
with their internal representation supplied.
Update the testsuite accordingly.

howto install_addend
This adds a new flag to the reloc howtos that can be used to
incrementally change targets over to simple bfd_install_relocation
that just installs the addend without any weird adjustments.
I've made a few other changes to bfd_install_relocation, removing dead
code and comments that are really only applicable to
bfd_perform_relocation.
There is also a reloc offset bounds check change. I've moved the
check to where data is accessed, as it seems reasonable to me to not
perform the check unless it is needed. There is precedence for this;
Relocations against absolute symbols already avoided the check.
I also tried always performing the reloc offset check, and ran into
testsuite failures due to _NONE and _ALIGN relocs at the end of
sections. These likely would be fixed if all such reloc howtos had
size set to zero, but I would rather not edit lots of files when it
involves checking that target code does not use the size.

PowerPC: fix for gdb.reverse/finish-precsave.exp and gdb.reverse/finish-reverse.exp
PR record/29927 - reverse-finish requires two reverse next instructions to
reach previous source line
PowerPC uses two entry points called the local entry point (LEP) and the
global entry point (GEP). Normally the LEP is used when calling a
function. However, if the table of contents (TOC) value in register 2 is
not valid the GEP is called to setup the TOC before execution continues at
the LEP. When executing in reverse, the function finish_backward sets the
break point at the alternate entry point (GEP). However if the forward
execution enters via the normal entry point (LEP), the reverse execution
never sees the break point at the GEP of the function. Reverse execution
continues until the next break point is encountered or the end of the
recorded log is reached causing gdb to stop at the wrong place.
This patch adds a new address to struct execution_control_state to hold the
address of the alternate function start address, known as the GEP on
PowerPC. The finish_backwards function is updated. If the stopping point
is between the two entry points (the LEP and GEP on PowerPC), the stepping
range is set to execute back to the alternate entry point (GEP on PowerPC).
Otherwise, a breakpoint is inserted at the normal entry point (LEP on
PowerPC).
Function process_event_stop_test checks uses a stepping range to stop
execution in the caller at the first instruction of the source code line.
Note, on systems that only support one entry point, the address of the two
entry points are the same.
Test finish-reverse-next.exp is updated to include tests for the
reverse-finish command when the function is entered via the normal entry
point (i.e. the LEP) and the alternate entry point (i.e. the GEP).
The patch has been tested on X86 and PowerPC with no regressions.

X86: reverse-finish fix
PR record/29927 - reverse-finish requires two reverse next instructions to
reach previous source line
Currently on X86, when executing the finish command in reverse, gdb does a
single step from the first instruction in the callee to get back to the
caller. GDB stops on the last instruction in the source code line where
the call was made. When stopped at the last instruction of the source code
line, a reverse next or step command will stop at the first instruction
of the same source code line thus requiring two step/next commands to
reach the previous source code line. It should only require one step/next
command to reach the previous source code line.
By contrast, a reverse next or step command from the first line in a
function stops at the first instruction in the source code line where the
call was made.
This patch fixes the reverse finish command so it will stop at the first
instruction of the source line where the function call was made. The
behavior on X86 for the reverse-finish command now matches doing a
reverse-next from the beginning of the function.
The proceed_to_finish flag in struct thread_control_state is no longer
used. This patch removes the declaration, initialization and setting of
the flag.
This patch requires a number of regression tests to be updated. Test
gdb.mi/mi-reverse.exp no longer needs to execute two steps to get to the
previous line. The gdb output for tests gdb.reverse/until-precsave.exp
and gdb.reverse/until-reverse.exp changed slightly. The expected result in
tests gdb.reverse/amd64-failcall-reverse.exp and
gdb.reverse/singlejmp-reverse.exp are updated to the correct expected
result.
This patch adds a new test gdb.reverse/finish-reverse-next.exp to test the
reverse-finish command when returning from the entry point and from the
body of the function.
The step_until proceedure in test gdb.reverse/step-indirect-call-thunk.exp
was moved to lib/gdb.exp and renamed cmd_until.
The patch has been tested on X86 and PowerPC to verify no additional
regression failures occured.

* The base instruction VCVT + NE for IT predication when inside an IT block.
* The MVE instruction VCVTN + E in the Else of a VPT block.

```
int test_function(float value)
{
int ret_val = 10;

GCC generates a VCVTNE instruction based on the `truncsisf2_vfp`
pattern, which will look like:
`vcvtne.s32.f32 s-reg, s-reg`
This still triggers an error due to being misidentified as "vcvtn+e"

patterns (these have all been added to the testing of this patch).
This class of errors was previously worked around by:

which addressed this by looking at the operand types, however,
that isn't adequate to cover all the extra cases that have been

sim: m32r: fix typos in stamp depends
Copying & pasting the first rule missed updating the dep to the right
stamp file.

sim: igen: simplify build logic a little
Now that all ports (that use igen) build in the top-level and depend
on igen, we can move the conditional logic out of configure. We also
switch from noinst_LIBRARIES to EXTRA_LIBRARIES so that the library
is only built when needed (i.e. the igen tool is used).

sim: build: drop depdir subdir hack
Now that all the ports compile some C files in their arch dirs, Automake
guarantees creating the depdir for us, so we can drop our configure hack.

sim: common: simplify modules.c deps
Now that all ports (other than ppc) build in the top-level, we don't
need to expand all the modules.c targets as a recursive dep. Each
port depends on their respective file now, and the ppc port doesn't
use it at all.

sim: common: move modules.c to source tracking
This makes sure the arch-specific modules.c wildcard is matched and
not the common/%.c so that we compile it correctly. It also makes
sure each subdir has depdir logic enabled.

sim: common: move libcommon.a dep to ppc code
Rather than force this to be built ahead of time for all targets,
move the dep to the ppc code since it's the only user of it now.

sim: build: drop most recursive build deps
Now that we build these objects in the top dir & generate modules.c
there, we don't need to generate them all first -- we can let the
normal dependency graph take care of building things in parallel.

sim: common: move libcommon.a objects to sources
This simplifies the build logic and avoids an Automake bug where the
common_libcommon_a_OBJECTS variable isn't set in the arch libsim.a
DEPENDENCIES for targets that, alphabetically, come before "common".
We aren't affected by that bug with the current code, but as we move
things out of SIM_ALL_RECURSIVE_DEPS and rely on finer dependencies,
we will trip over it.

Pass internal gdb flags to --configuration invocations
The test suite uses the --configuration flag to feature-test gdb.
However, when I added this, I neglected to pass the internal gdbflags
to this, causing an error, which then caused failures in the test
suite (which would not be seen if you'd ever run "make install").
This patch fixes the bug. Tested by removing my install tree first,
to verify that I could reproduce the failure.
