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.

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.

This patch simplifies compute_and_set_names in a couple of ways.
First, it changes one spot to use obstack_strndup, which is
equivalent, but more concise.
Second, the function ends with two calls to symbol_set_demangled_name.
This can be simplified to a single call.

When running gdb.python/lib-types.exp, we have an xpass:
...
(gdb) python print (str (typedef_const_typedef_class1_ref_obj.type))^M
typedef_const_typedef_class1_ref^M
(gdb) XPASS: gdb.python/lib-types.exp: \
python print (str (typedef_const_typedef_class1_ref_obj.type)) \
(PRMS gcc/55641)
...
When running the same with gcc 4.8, we have an xfail instead:
...
(gdb) python print (str (typedef_const_typedef_class1_ref_obj.type))^M
const typedef_const_typedef_class1_ref^M
(gdb) XFAIL: gdb.python/lib-types.exp: \
python print (str (typedef_const_typedef_class1_ref_obj.type)) \
(PRMS gcc/55641)
...
Fix the xpass by xfailing only for the gcc 4.8 pattern.
Tested on x86_64-linux, with:
- gcc 7.5.0
- gcc 4.8.5
- clang 5.0.2

(gdb) XPASS: gdb.ada/funcall_ref.exp: ptype get ("Hello world!")
...
The xfails are documented in funcall_ref.exp:
...
# Currently, GCC describes such functions as returning pointers (instead of
# references).
setup_xfail *-*-*
...
Using gnatmake 4.8, we can reproduce the XFAILs:
...
(gdb) p get ("Hello world!")^M
$1 = (access foo.bar) 0x6147b0 <system.secondary_stack.chunk+48>^M
(gdb) XFAIL: gdb.ada/funcall_ref.exp: p get ("Hello world!")
ptype get ("Hello world!")^M
type = access record^M
n: natural;^M
s: access array (1 .. n) of character;^M
end record^M
(gdb) XFAIL: gdb.ada/funcall_ref.exp: ptype get ("Hello world!")
...
Fix the XPASSes by:
- removing the xfail setup
- switching the order of the two tests
- detecting the "access record" type and declaring the first test unsupported,
and skipping the second test
Tested on x86_64-linux, both with gnatmake 4.8.5 and gnatmake 7.5.0.

This is a simple cleanup. These functions used to use the objfile's
obstack for allocation in the hash tables, but they don't anymore.
Remove the unnecessary objfile parameters, which in turn allows removing
some local variables.

GCC's config/ChangeLog since the last time this merge was done
(in the binutils-gdb commit 0b4d000cc4e8e77c823) is included at the
end of this commit message.
It is worth noting that the binutils-gdb commit 301a9420d947da1458
added the file config/debuginfod.m4 which is not present in GCC's
config/ directory. This file is preserved, unmodified, after this
commit.
In order to regenerate all of the configure files, I configured with
--enable-maintainer-mode, and built the 'all' target. I then did the
same thing on a source tree without this patch, and only committed
those files that changed when this patch was added.

Before commit d4295de4f3 "[gdb/testsuite] Handle missing gnatmake in
gnat_runtime_has_debug_info", calling the gdb_caching_proc
gnat_runtime_has_debug_info could generate a pass because of using
gdb_compile_ada.
This has been fixed in that commit by using a factored out variant
gdb_compile_ada_1, which does not call pass.
Additionally, fix cases like this in more generic way: by ignoring pass calls
during execution of a gdb_caching_proc.

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.

We can't use c99 without enabling c99 support for older compilers
that don't enable c99 by default. So if you want to use c99 contructs
in binutils you'll need to first arrange for -std=c99 to be passed to
older compilers.

Implement RISC-V/Linux support for both RV64 and RV32 systems, including
XML target description handling based on features determined, GPR and
FPR regset support including dynamic sizing of the latter, and software
breakpoint handling. Define two NT_FPREGSET regsets of a different size
matching the FPR sizes supported for generic `gdbserver' code to pick
from according to what the OS supplies.
Also handle a glibc bug where ELF_NFPREG is defined in terms of NFPREG,
however NFPREG is nowhere defined.

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.
