Testsuite: Ensure changing directory does not break the log file
get_compiler_info switches to a new log file before checking the compiler
to ensure the checks are not logged. Afterwards it restores back to using
the original log file. However, the logfile uses a relative path name -
if the current test has changed the current directory then all further
output for the test will be lost. This can confuse the code that collates
the main gdb.log file at the end of a FORCE_PARALLEL run.
fullpath-expand.exp calls gdb_compile after changing the current directory.
The "Ensure stack protection is off for GCC" patch added a call to
get_compiler_info from inside of gdb_compile, causing log file collection
to break for FORCE_PARALLEL runs.
The ideal solution would be to ensure the log file is always created using
an absolute path name. However, this is set at multiple points in
Makefile.in and in some instances just relies on dejagnu common code to set
the log file directory to "."
The simpler and safer solution is to override the builtin cd function. The
new function checks the current log file and if the path is relative, then
it resets the logging using an absolute path. Finally it calls the builtin
cd. This ensures get_compiler_info (and any other code) can correctly
backup and restore the current log file.

Fortran function calls with arguments
Prior to this patch, calling functions on the inferior with arguments and
then using these arguments within a function resulted in an invalid
memory access. This is because Fortran arguments are typically passed as
pointers to values.
It is possible to call Fortran functions, but memory must be allocated in
the inferior, so a pointer can be passed to the function, and the
language must be set to C to enable C-style casting. This is cumbersome
and not a pleasant debug experience.
This patch implements the GNU Fortran argument passing conventions with
caveats. Firstly, it does not handle the VALUE attribute as there is
insufficient DWARF information to determine when this is the case.
Secondly, functions with optional parameters can only be called with all
parameters present. Both these cases are marked as KFAILS in the test.
Since the GNU Fortran argument passing convention has been implemented,
there is no guarantee that this patch will work correctly, in all cases,
with other compilers.
Despite these limitations, this patch improves the ease with which
functions can be called in many cases, without taking away the existing
approach of calling with the language set to C.

Change the_dummy_target to be a global

Here, 0x142b0b0 is the singleton dummy target. It seems to me that

Remove excess calls to gdb_flush
A customer noticed some mildly odd MI output, where CLI output was
split into multiple MI strings at unusual boundaries, like this:
~"$1 = (b => true"
~", p => 0x407260"
This is technically correct according to the MI spec, but still
unusual, in that there's no particular reason for the string to be
split where it is.
I tracked this down to a call to gdb_flush in generic_val_print.
Then, I went through all calls to gdb_flush and removed the ones I
thought were superfluous. In particular:
* Any call in the value-printing code;
* Likewise the type-printing code (just a single call); and
* Any call that immediately followed a printf that obviously
ended with a newline, my belief being that gdb's standard output
streams are line buffered (by inheriting the behavior from stdio)

gdbserver short-circuit-argument-list failures
This patch fixes test case failures observed when running
short-circuit-argument-list.exp with gdb server boards. Thanks to Sergio
Durigan Junior for pointing this out.
Assertions failed with the native{,-extended}-gdbserver boards as the
standard output from the test program appears in a different location
than observed on non-gdbserver boards. This standard output was used to
determine whether a function, which had been logically short-circuited,
was called or not. Since the location of the standard out cannot be
relied upon to verify this, a new mechanism was needed.
The test program now records function calls in variables named the same
as the function with a "_called" suffix. These variables can then be
queried from the test case to verify the occurrence of a call.
A method to reset the call counts has been included in the test case, so
that any future assertions added to this test can ensure a fresh set of
initial values before proceeding. Not resetting values between groups of
assertions creates a dependency between them, which increases the
likelihood that a single failure causes subsequent assertions to fail.

Testsuite: Catch gdbserver socket listen errors
When launching gdbserver, the testsuite checks for binding failure but
does not check for failure to listen to socket error (which can happen
due to another gdbserver binding to the socket at the same time).
When this error occurs, the test will ignore the error and connect GDB
to the failed port. This may succeed and GDB will now be connected to
the gdbserver from another test. This eventually causes both tests to
fail.
When running the tests suite with native-gdbserver across many cores,
this issue may happen once or twice, each causing random failures for
two .exp testscripts.
Example gdb.log output for the failure:
The testsuite sucessfully notices a failure to connect to port 2348.
It launches again with port 2349, which also fails. The testsuite
ignores this error and uses gdb to connect to the port - which succeeds.

Fix regcache leak, and avoid possible regcache access after detach.
Valgrind reports leaks like the below in various tests,
e.g. gdb.threads/attach-slow-waitpid.exp, gdb.ada/task_switch_in_core.exp, ...
Fix the leak by clearing the regcache when detaching from an inferior.
Note that these leaks are 'created' when GDB exits,
when the regcache::current_regcache is destroyed : the elements
of the forward_list are pointers, and the 'pointed to' memory is not
deleted by the forward_list destructor.
Nevertheless, fixing this leak is good as it makes a bunch of
tests 'leak clean'.
Also, it seems strange to keep a register cache for a process from
which GDB detached : it is not clear if this cache is still valid
after detach. And effectively, when clearing only the regcache,
(and not the frame cache), then the frame cache was still 'pointing'
at this regcache and was used when switching to the child process
in the test gdb.threads/watchpoint-fork.exp, which seems strange.
So, we solve the leak and avoid possible accesses to the regcache
and frame cache of the detached inferior, by clearing both the
regcache and the frame cache.
Tested on debian/amd64, natively, under Valgrind,
and with make check RUNTESTFLAGS="--target_board=native-gdbserver".

Prevent overflow in rl_set_screen_size
GDB calls rl_set_screen_size in readline with the current screen size,
measured in rows and columns. To represent "infinite" sizes, GDB
passes in INT_MAX; however, since rl_set_screen_size internally
multiplies the number of rows and columns, this causes a signed
integer overflow. To prevent this we can instead pass in the
approximate square root of INT_MAX (which is still reasonably large),
so that even when the number of rows and columns is "infinite" we
don't overflow.

Use Python 2.[67] / 3.X / PEP 3118 buffer protocol
This patch removes the non-IS_PY3K code in infpy_write_memory()
and infpy_search_memory(). In both cases, the remaining code
from these ifdefs is related to use of the PEP 3118 buffer protocol.
(Deleted code is either due to simplification or related to use of the
old buffer protocol.) PEP 3118 is sometimes referred to as the "new"
buffer protocol, though it's not that new anymore.
The link below describes new features in Python 2.6. In particular,
it says that the buffer protocol described by PEP 3118 is in Python
2.6. It also says (at the top of the page) that Python 2.6 was
released on Oct 1, 2008.
https://docs.python.org/3/whatsnew/2.6.html#pep-3118-revised-buffer-protocol
The last security release for the Python 2.6 series was 2.6.9. It was
released on Oct 29, 2013. According to this document...
https://www.python.org/download/releases/2.6.9/
...support for the 2.6 series has ended:
With the 2.6.9 release, and five years after its first release,
the Python 2.6 series is now officially retired. All official
maintenance for Python 2.6, including security patches, has ended.
For ongoing maintenance releases, please see the Python 2.7
series.
As noted earlier, Python 2.6, Python 2.7, and Python 3.X all have
support for the PEP 3118 buffer protocol. Python releases prior
to 2.6 use an older buffer protocol. Since Python 2.6 has been
retired for a good while now, it seems reasonable to me to remove
code using the older buffer protocol from GDB.
I have also simplified some of the code via use of the Py_buffer
unique_ptr specialization which I introduced in the two argument
gdb.Value constructor patch series. Therefore, there is a dependency
on patch #1 from that series.
I have tested against both Python 2.7.15 and 3.7.2. I see no
regressions among the non-racy tests. I've also verified that
PyBuffer_Release is being called when the affected functions exit
while running the tests in gdb.python/py-inferior.exp by hand. I've
also tried running valgrind on GDB while running this test, but I'm
puzzled by the results that I'm seeing - I'm seeing no additional
leaks when I comment out the Py_buffer_up lines that I introduced.
That said, I'm not seeing any leaks that obviously originate from
either infpy_write_memory() or infpy_search_memory().

Testsuite: Allow multiple lines of "as" in testsuite.
Committed on behalf of Matthew Malcomson.
This allows checking the command line parsing more easily than before by
allowing many command line invokations from the same .d file.
Each line is used as a set of flags, and the tests are ran against the output
of the assembler with each set.
Each line of assembler is treated as another set of tests (as if the test file
were copied to another with a different #as: line).

gdb: Handle alignment for C++ structures with static members
In 'type_align' when computing the alignment of a structure we should
not consider the alignment of static structure members, these are

gdb: Restructure type_align and gdbarch_type_align
This commit restructures the relationship between the type_align
function and the gdbarch_type_align method.
The problem being addressed with this commit is this; previously the
type_align function was structured so that for "basic" types (int,
float, etc) the gdbarch_type_align hook was called, which for
"compound" types (arrays, structs, etc) the common type_align code has
a fixed method for how to extract a "basic" type and would then call
itself on that "basic" type.
The problem is that if an architecture wants to modify the alignment
rules for a "compound" type then this is not currently possible.
In the revised structure, all types pass through the
gdbarch_type_align method. If this method returns 0 then this
indicates that the architecture has no special rules for this type,
and GDB should apply the default rules for alignment. However, the
architecture is free to provide an alignment for any type, both
"basic" and "compound".
After this commit the default alignment rules now all live in the
type_align function, the default_type_align only ever returns 0,
meaning apply the default rules.
I've updated the 3 targets (arc, i386, and nios2) that already
override the gdbarch_type_align method to fit the new scheme.
Tested on X86-64/GNU Linux with no regressions.

gdb/riscv: Use legacy register numbers in default target description
When the target description support was added to RISC-V, the register
numbers assigned to the fflags, frm, and fcsr control registers in the
default target descriptions didn't match the register numbers used by
GDB before the target description support was added.
What this means is that if a tools exists in the wild that is using
hard-coded register number, setup to match GDB's old numbering, then
this will have been broken (for fflags, frm, and fcsr) by the move to
target descriptions. QEMU is such a tool.
There are a couple of solutions that could be used to work around this
issue:
- The user can create their own xml description file with the
register numbers setup to match their old tool, then load this by
telling GDB 'set tdesc filename FILENAME'.
- Update their old tool to use the newer default numbering scheme, or
better yet add proper target description support to their tool.
- We could have RISC-V GDB change to maintain the old defaults.
This patch changes GDB back to using the old numbering scheme.
This change is only visible to remote targets that don't supply their
own xml description file and instead rely on GDB's default numbering.
Note that even though 32bit-cpu.xml and 64bit-cpu.xml have changed,
the corresponding .c file has not, this is because the numbering added
to the registers in the xml files is number 0, this doesn't result in
any new C code being generated .

Fix crash when loading dwp files
When loading dwp files, we create an array of ELF sections indexed by the ELF
section index in the dwp file. The size of this array is calculated by
section_count, as returned by bfd_count_sections, plus 1 (to account for the
null section at index 0). However, when loading the bfd file, strtab/symtab
sections are not added to the list, nor do they increment section_count, so
section_count is actually smaller than the number of ELF sections.
This happens to work when using GNU dwp, which lays out .debug section first,
with sections like .shstrtab coming at the end. Other tools, like llvm-dwp, put
.strtab first, and gdb crashes when loading those dwp files.
For instance, with the current state of gdb, loading a file like this:
$ readelf -SW <file.dwp>
[ 0] <empty>
[ 1] .debug_foo PROGBITS ...
[ 2] .strtab STRTAB ...
... results in section_count = 2 (.debug is the only thing placed into
bfd->sections, so section_count + 1 == 2), and sectp->this_idx = 1 when mapping
over .debug_foo in dwarf2_locate_common_dwp_sections, which passes the
assertion that 1 < 2.
However, using a dwp file produced by llvm-dwp:
$ readelf -SW <file.dwp>
[ 0] <empty>
[ 1] .strtab STRTAB ...
[ 2] .debug_foo PROGBITS ...
... results in section_count = 2 (.debug is the only thing placed into
bfd->sections, so section_count + 1 == 2), and sectp->this_idx = 2 when mapping
over .debug_foo in dwarf2_locate_common_dwp_sections, which fails the assertion
that 2 < 2.
The assertion hit is:
gdb/dwarf2read.c:13009: internal-error: void dwarf2_locate_common_dwp_sections(bfd*, asection*, void*): Assertion `elf_section_nr < dwp_file->num_sections' failed.
This patch changes the calculation of section_count to use elf_numsections,
which should return the actual number of ELF sections.
