gdbserver: start turning the target ops vector into a class
This is the beginning of a series of patches where the goal is to turn
the target ops vector into a class and all the target op function
pointers into methods of this class.
Currently, the target ops is a struct of function pointers. At the
end of the series, it becomes a class with methods, and the existing
low target definitions become subclasses. That is, we end up with the
following class hierarchy:
process_stratum_target
^
|-- linux-low
|-- lynx-low
|-- nto-low
|-- win32-low
process_stratum_target either defines the default behavior for the
target ops or leaves them as pure virtual for the subclasses to
override.
The transformation is done by first introducing a helper class, called
'process_target', that is initially empty. An instance of this class
is added to the end of the current target ops vector. This new field
is called 'pt'. We will gradually carry target ops to the new class,
one by one, whereas the invocation of the target op will be converted
to a method call on 'pt'.
For instance, target op 'attach' is currently invoked as
(*the_target->attach) (args)
After moving 'attach' as a method to 'process_target', it will be
invoked as
the_target->pt->attach (args)
In this process, the concrete target vector definitions
(e.g. linux-low, win32-low, nto-low, etc.) are turned into derived
classes of 'process_target', so that they can either inherit the
default behavior of the target ops or can override the method.
We prefer to make this transition gradually rather than in a single
giant patch, to yield bite-size patches. The goal is that after each
patch gdbserver will still be buildable and testable.
The general rule of thumb when converting a target op to a method is
this:
(1) If the function call is protected with a NULL-check with an
obvious default behavior, simply implement that default behavior in
the base class (e.g.: supports_non_stop).
(2) If there is no NULL-check guard, the method becomes pure
virtual, and the derived targets are required to implement the method
(e.g.: attach).
(3) If there is a NULL-check but no apparent default behavior, or if
the NULL-check is utilized to populate a feature support packet,
introduce a 'supports_XYZ' method (e.g.: pid_to_exec_file).
The overall strategy is to preserve the existing behavior as much as
possible.
When we're done moving all the target ops into 'process_target', the
target op vector will contain nothing but the field 'pt'. At that
point, the auxiliary class 'process_target' will simply meld into
'process_stratum_target' and the method calls of the form
'the_target->pt->xyz' will be turned into 'the_target->xyz'.
The "linux-low" target has been built and reg-tested on X86_64 Linux
(Ubuntu). The "win32-low" target has been built (but not tested) via
cross-compilation to a x86_64-w64-mingw32 target. The "lynx-low" and
"nto-low" targets were neither built nor tested.

gdb: Allow more control over where to find python libraries
The motivation behind this commit is to make it easier to bundle the
Python *.py library files with GDB when statically linking GDB against
libpython. The Python files will be manually added into the GDB
installation tree, and GDB should be able to find them at run-time.
The installation tree will look like this:
.
|-- bin/
|-- include/
|-- lib/
| `-- python3.8/
`-- share/
The benefit here is that the entire installation tree can be bundled
into a single archive and copied to another machine with a different
version of Python installed, and GDB will still work, including its
Python support.
In use the new configure options would be used something like this,
first build and install a static Python library:
mkdir python
cd python
# Clone or download Python into a src/ directory.
mkdir build
export PYTHON_INSTALL_PATH=$PWD/install
cd build
../src/configure --disable-shared --prefix=$PYTHON_INSTALL_PATH
make
make install
Now build and install GDB:
mkdir binutils-gdb
cd binutils-gdb
# Clone or download GDB into a src/ directory.
mkdir build
export GDB_INSTALL_DIR=$PWD/install
cd build
../src/configure \
--prefix=$GDB_INSTALL_DIR \
--with-python=$PYTHON_INSTALL_PATH/bin/python3 \
--with-python-libdir=$GDB_INSTALL_DIR/lib
make all-gdb
make install-gdb
Finally, copy the Python libraries into the GDB install:
cp -r $PYTHON_INSTALL_DIR/lib/python3.8/ $GDB_INSTALL_DIR/lib
After this the Python src, build, and install directories are no
longer needed and can be deleted.
If the new --with-python-libdir option is not used then the existing
behaviour is left unchanged, GDB will look for the Python libraries in
the lib/ directory within the python path. The concatenation of the
python prefix and the string 'lib/' is now done at configure time,
rather than at run time in GDB as it was previous, however, this was
never something that the user had dynamic control over, so there's no
loss of functionality.
gdb/ChangeLog:
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac: Add --with-python-libdir option.
* main.c: Use WITH_PYTHON_LIBDIR.

bfd_size_type to size_t
bfd_size_type was invented a long time ago in the K&R days. Many
places in binutils ought to be using size_t instead (and there are
lots of places that use long or unsigned long that really ought to use
size_t too). Note that you can't change everything over to size_t: A
32-bit host needs a larger type than size_t to support reading and
processing of 64-bit ELF object files. This patch just tidies some
of the more obvious uses of bfd_size_type that could be size_t. There
no doubt are more lurking in the source. Incidentally, practically
all functions used for output of object files can use size_t and don't
need to worry about overflow of size expressions. If you have
something like
symcount * sizeof (void *)
when symcount is counting symbols already in memory then you know that
this expression can't overflow since the size of a symbol in memory is
larger by far than that of a pointer.

gdb/riscv: Update API for looking up target descriptions
In preparation for adding the RISC-V gdbserver, this commit
restructures the API for looking up target descriptions.
The current API is riscv_create_target_description, which creates a
target description from a riscv_gdbarch_features, but also caches the
created target descriptions so that for a given features object we
always get back the same target description object. This is important
for GDB due to the way gdbarch objects are reused.
As the same target description is always returned to GDB, and can be
returned multiple times, it is returned as a const, however, the
current cache actually stores a non-const target description. This is
improved in this patch so that the cache holds a const target
description.
For gdbsever, this caching of the target descriptions is not needed,
the gdbserver looks up one target description to describe the target
it is actually running on and that is it. Further the gdbserver
actually needs to modify the target description that is looked up, so
for the gdbsever, returning a const target description is not
acceptable.
This commit aims to address this by creating two parallel target
description APIs, on is the old riscv_create_target_description,
however, this no longer performs any caching, and just creates a new
target description, and returns it as non-const.
The second API is riscv_lookup_target_description, this one performs
the caching, and calls riscv_create_target_description to create a
target description when needed.
In order to make sure the correct API is used in the correct place I
have guarded the code using the GDBSERVER define. For GDB the
riscv_create_target_description is static, and not generally usable
throughout GDB, only the lookup API is global. In gdbserver, the
lookup functions, and the cache are not defined or created at all,
only the riscv_create_target_description API is available.
There should be no user visible changes after this commit.

if GDBSERVER is not defined.

gdb: change print format of flag enums with value 0
If a flag enum has value 0 and the enumeration type does not have an
enumerator with value 0, we currently print:
$1 = (unknown: 0x0)
I don't like the display of "unknown" here, since for flags, 0 is a
an expected value. It just means that no flags are set. This patch
makes it so that we print it as a simple 0 in this situation:
$1 = 0
If there is an enumerator with value 0, it is still printed using that
enumerator, for example (from the test):
$1 = FE_NONE

gdb: allow duplicate enumerators in flag enums
I have come across some uses cases where it would be desirable to treat
an enum that has duplicate values as a "flag enum". For example, this
one here [1]:
enum membarrier_cmd {
MEMBARRIER_CMD_QUERY = 0,
MEMBARRIER_CMD_GLOBAL = (1 << 0),
MEMBARRIER_CMD_GLOBAL_EXPEDITED = (1 << 1),
MEMBARRIER_CMD_REGISTER_GLOBAL_EXPEDITED = (1 << 2),
MEMBARRIER_CMD_PRIVATE_EXPEDITED = (1 << 3),
MEMBARRIER_CMD_REGISTER_PRIVATE_EXPEDITED = (1 << 4),
MEMBARRIER_CMD_PRIVATE_EXPEDITED_SYNC_CORE = (1 << 5),
MEMBARRIER_CMD_REGISTER_PRIVATE_EXPEDITED_SYNC_CORE = (1 << 6),
/* Alias for header backward compatibility. */
MEMBARRIER_CMD_SHARED = MEMBARRIER_CMD_GLOBAL,
};
The last enumerator is kept for backwards compatibility. Without this
patch, this enumeration wouldn't be considered a flag enum, because two
enumerators collide. With this patch, it would be considered a flag
enum, and the value 3 would be printed as:
MEMBARRIER_CMD_GLOBAL | MEMBARRIER_CMD_GLOBAL_EXPEDITED
Although if people prefer, we could display both MEMBARRIER_CMD_GLOBAL
and MEMBARRIER_CMD_SHARED in the result. It wouldn't be wrong, and
could perhaps be useful in case a bit may have multiple meanings
(depending on some other bit value).

gdb: fix printing of flag enums with multi-bit enumerators
GDB has this feature where if an enum looks like it is meant to
represent binary flags, it will present the values of that type as a
bitwise OR of the flags that are set in the value.
The original motivation for this patch is to fix this behavior:
enum hello { AAA = 0x1, BBB = 0xf0 };
(gdb) p (enum hello) 0x11
$1 = (AAA | BBB)
This is wrong because the bits set in BBB (0xf0) are not all set in the
value 0x11, but GDB presents it as if they all were.
I think that enumerations with enumerators that have more than one bit
set should simply not qualify as "flag enum", as far as this
heuristic is concerned. I'm not sure what it means to have flags of
more than one bit. So this is what this patch implements.
I have added an assert in generic_val_print_enum_1 to make sure the flag
enum types respect that, in case they are used by other debug info
readers, in the future.
I've enhanced the gdb.base/printcmds.exp test to cover this case. I've
also added tests for printing flag enums with value 0, both when the
enumeration has and doesn't have an enumerator for value 0.
