Disable R_X86_64_PLT32 generation as branch marker on Solaris/x86
The fix H.J. implemented for PR gas/22791 in the thread starting at
[PATCH] x86-64: Treat PC32 relocation with branch as PLT32
https://sourceware.org/ml/binutils/2018-02/msg00065.html
is causing problems on Solaris/x86. The native linker is strongly
preferred there, and there's no intention of implementing the linker
optimization he plans there. Besides, the kernel runtime linker,
otherwise has no need to deal with that reloc at all, and instead of
adding (possibly even more) workarounds with no benefit, it seems
appropriate to disable the R_X86_64_PLT32 generation as branch marker on
Solaris/x86 in the first place.
The patch itself is trivial, the only complication is adapting the
testsuite. Since I've found no way to have conditional sections in the
.d files, I've instead used the solution already found elsewhere of
having separate .d files for the affected tests in an i386/solaris
subdirectory and skipping the original ones.
Tested on amd64-pc-solaris2.11 and x86_64-pc-linux-gnu without
regressions.

Use -qualified flag when setting temporary breakpoint in start command
When using the "start" command, GDB puts a temporary breakpoint on the
"main" symbol (we literally invoke the tbreak command). However, since
it does wild matching by default, it also puts a breakpoint on any C++
method or "main" function in a namespace. For example, when debugging
GDB, it creates a total of 24 locations:
(gdb) start
Temporary breakpoint 1 at 0x198c1e9: main. (24 locations)
as there are a bunch of methods called main in the selftests, such as
selftests::string_view::capacity_1::main()
If such method was called in the constructor of a global object, or a
function marked with the attribute "constructor", then we would stop at
the wrong place. Also, this causes a few extra symtabs (those that
contain the "wrong" mains) to be expanded for nothing.
The dummiest, most straightforward solution is to add -qualified when
invoking tbreak. With this patch, "start" creates a single-location
breakpoint, as expected.
I copied the start.exp test to start-cpp.exp and made it use a C++ test
file, which contains two main functions. The new test verifies that the
output of "start" is the output we get when we set a single-location
breakpoint.

Simplify exception handling
Now that cleanups have been removed, TRY/CATCH can't be SJLJ-based any
more. This patch simplifies the exception handling code, by removing
the non-working variants.
Note that the "pure" C++ exception handling code is removed as well; I
think the route forward must be to change exceptions to be
self-destructing, so that try_scope_depth can simply be removed.
Some longjmp-based code remains, as it is needed to throw an exception
through readline.

Make "all" depend on "info"
I've broken "make info" a couple of times now, because I sometimes
forget to run "make info" after modifying a Texinfo file.
I don't know why gdb's "make all" doesn't build the info pages. I
suspect this was some Cygnus-local oddity back in the day.
This patch changes doc/Makefile.in so that the info pages are built by
"make all". As a point of reference, Automake has essentially always
worked this way. According to the Automake manual (I didn't
double-check) this is required by the GNU coding standards.
The first time I sent this patch, I mentioned that I wanted to look
into some existing bugs in bugzilla about missing "makeinfo".
However, today I tried and I discovered that BFD requires makeinfo,
and builds its info file as part of "all". So, I think this change
doesn't worsen the situation for users in any way, and can simply go
in.

Revert the header-sorting patch
Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).
So, I'm reverting the patch. I may try again after fixing the issues
pointed out.

Use linux_get_auxv to get AT_PHDR in the PPC stub
This patch fixes a build error due to a call to ppc_get_auxv that was
left over after linux_get_hwcap and linux_get_hwcap2 were introduced
in:
974c89e0882ddb03e294eca76a9e3d3bef90eacf gdbserver: Add
linux_get_hwcap
Because the missing call fetched AT_PHDR and not AT_HWCAP,
linux_get_auxv is now visible.
This use also required ppc_get_auxv to return a status variable
indicating that the AT_PHDR entry was not found separately from the
actual value of of the auxv entry. Therefore, the new linux_get_auxv
function is changed to return a status variable and write the entry
value to a pointer passed as an argument.
Note that linux_get_hwcap and linux_get_hwcap2 still use the return
value as both an indicator of that the entry wasn't found and as the
actual value of the entry.
gdb/gdbserver/ChangeLog:
2019-04-05 Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
* linux-low.c (linux_get_auxv): Remove static. Return auxv entry
value in argument pointer, return 1 if the entry is found and 0

type stack handling to this class. Parsers that wish to use this
facility must now instantiate this class somehow. I chose this
approach because a minority of the existing parsers require this.

Remove paren_depth global
This removes the "paren_depth" global. In most cases, it is made into
a static global in a given parser. I consider this a slight
improvement, because it makes it clear that the variable isn't used

is the Rust parser, which already incorporates all local state into a
transient object; in this case the parser depth is now a member.

PowerPC bc extended branch mnemonics and "y" hints
This patch fixes a problem with disassembly of branch instructions
for processors complying with PowerPC ISA versions prior to version
2.0, ie. those that use "y" bit branch taken hints. Many of the
extended bcctr and bclr mnemonics that should have disassembled with a
"-" suffix, ie. not taken, did not display the "-" due to the ordering
in powerpc_opcodes. I believe it's been that way from the original
85dcf36d72b commit of ppc-opc.c.
I've also added a BH field (optional) to a few opcodes. This gives
better disassembly in raw mode, showing the branch taken hint in the
mnemonic as is done for bc. It would be reasonable to add a BH
field to all bcctr, bclr, and bctar extended mnemonics but that runs
into a small difficulty: Currently we print all or none of the
optional operands. That means for example that "bgectr cr2" would
display as "bgectr cr2,0" if a BH field is added to bgectr.
* ppc-opc.c (XLBH_MASK): Subtract off BH field from BB_MASK.
(powerpc_opcodes): Reorder bcctr and bclr extended mnemonics
to favour printing of "-" branch hint when using the "y" bit.

I've extended the test to check that all languages can call the

gdb: Add $_cimag and $_creal internal functions
Add two new internal functions $_cimag and $_creal that extract the
imaginary and real parts of a complex value.
These internal functions can take a complex value of any type 'float
complex', 'double complex', or 'long double complex' and return a
suitable floating point value 'float', 'double', or 'long double'.
So we can now do this:
(gdb) p z1
$1 = 1.5 + 4.5 * I
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) p $_creal (z1)
$4 = 1.5
The components of a complex value are not strictly named types in
DWARF, as the complex type is itself the base type. However, once we
are able to extract the components it makes sense to be able to ask
what the type of these components is and get a sensible answer back,
rather than the error we would currently get. Currently GDB says:
(gdb) ptype z1
type = complex double
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) ptype $
type = <invalid type code 9>
With the changes in dwarf2read.c, GDB now says:
(gdb) ptype z1
type = complex double
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) ptype $
type = double
Which seems to make more sense.

Fix internal error and improve 'set debug infrun 1'/target wait kind trace
The test gdb.threads/watchthreads-reorder.exp verifies that the
'set debug infrun 1' debug output does not crash GDB.
Under high load, the test can still cause a GDB internal error (see details
below).
This patch fixes this crash, and improves/factorises some wait kind traces.
Tested on debian/amd64 + run one test with 'set debug infrun 1'.
Changes compared to the first version:
* Handles the suggestions of Kevin to trace the relevant elements
of the wait status (this is done by calling target_waitstatus_to_string).
* Some other changes to factorise wait status tracing.
Note that using target_waitstatus_to_string instead of the 'locally printed'
status kind strings means that debug trace that was using strings such as:
"EXITED" or "TARGET_WAITKIND_EXITED"
will now use what is printed by target_waitstatus_to_string e.g.
"exited".

[GAS, Arm] CLI with architecture sensitive extensions
This patch adds a new framework to add architecture sensitive extensions, like
GCC does. This patch also implements all architecture extensions currently
available in GCC.
This framework works as follows. To enable architecture sensitive extensions
for a particular architecture, that architecture must contain an ARM_ARCH_OPT2
entry in the 'arm_archs' table. All fields here are the same as previous, with
the addition of a new extra field at the end to <name> it's extension table.
This <name>, corresponds to a <name>_ext_table of type 'struct arm_ext_table'.
This struct can be filled with three types of entries:
ARM_ADD (string <ext>, arm_feature_set <enable_bits>), which means +<ext> will
enable <enable_bits>
ARM_REMOVE (string <ext>, arm_feature_set <disable_bits>), which means
+no<ext> will disable <disable_bits>
ARM_EXT (string <ext>, arm_feature_set <enable_bits>, arm_feature_set
<disable_bits>), which means +<ext> will enable <enable_bits> and +no<ext>
will disable <disable_bits> (this is to be used instead of adding an
ARM_ADD and ARM_REMOVE for the same <ext>)
This patch does not disable the use of the old extensions, even if some of them
are duplicated in the new tables. This is a "in-between-step" as we may want to
deprecate the old table of extensions in later patches. For now, GAS will first
look for the +<ext> or +no<ext> in the new table and if no entry is found it
will continue searching in the old table, following old behaviour. If only an
ARM_ADD or an ARM_REMOVE is defined for <ext> and +no<ext> or +<ext> resp. is
used then it also continues to search the old table for it.
A couple of caveats:
- This patch does not enable the use of these architecture extensions with the
'.arch_extension' directive. This is future work that I will tend to later.
- This patch does not enable the use of these architecture extensions with the
-mcpu option. This is future work that I will tend to later.
- This patch does not change the current behaviour when combining an
architecture extension and using -mfpu on the command-line. The current
behaviour of GAS is to stage the union of feature bits enabled by both -march
and -mfpu. GCC behaves differently here, so this is something we may want to
revisit on a later date.

Jan pointed out problems with GCC debuginfo for -m32 builds

I am dropping the hand-tweaked assembler source file to workaround
this case.
While I would normally do something to accommodate this, in
this case, given the ubiquity of 64-bit systems today (where
the tests pass) and the apparent lack of urgency on the compiler
side (by users), I don't think the additional complexity and
maintenance costs are worth it. It will be very routinely tested
on 64-bit systems. [For example, at Red Hat, we always
test -m64 and -m32 configurations for all GDB releases.]

Allow really large fortran array bounds: TYPE_LENGTH to ULONGEST
This series is revisit of Siddhesh Poyarekar's patch from back in
2012. The last status on the patch is in the following gdb-patches
thread:
https://sourceware.org/ml/gdb-patches/2012-08/msg00562.html
It appears that Tom approved the patch, but Jan had some issues
with a compiler error that made the test fail on -m32 test runs.
He wrote up a hand-tweaked .S file to deal with it. Siddesh said
he would update tests. Then nothing.
Siddesh and Jan have both moved on since.
The patch originally required a large precursor patch to work.
I have whittled this down to/rewritten the bare minimum, and this
first patch is the result, changing the type of TYPE_LENGTH
to ULONGEST from unsigned int.
The majority of the changes involve changing printf format
strings to use %s and pulongest instead of %d.
gdb/ChangeLog:
* ada-lang.c (ada_template_to_fixed_record_type_1): Use
%s/pulongest for TYPE_LENGTH instead of %d in format
strings.

bfd: xtensa: fix shrink_dynamic_reloc_sections for export-dynamic
shrink_dynamic_reloc_sections must remove PLT entry that was created for
an undefined weak symbol in the presence of --export-dynamic option when
relaxation coalesces literals pointing to that symbol. This fixes the
following assertion:
ld: BFD (GNU Binutils) 2.31.1 internal error, aborting at
elf32-xtensa.c:3292 in elf_xtensa_finish_dynamic_sections

sim/common: convert sim-arange to use sim-inline
broke many simulator targets. I fixed aarch64 in a previous commit
without realising how many other target were also broken.
This commit adds the missing includes (sim-assert.h and libiberty.h),
which seem to be needed by many simulator targets, in a central
location, this should fix most builds.
sim/common/ChangeLog:
* sim-base.h: Add 'sim-assert.h' include.
* sim-basics.h: Add 'libiberty.h' include.
