This patch removes the leftover regformats .dat files for the arm
architecture. There are no longer relevant, since the arm architecture
has been converted to use feature-based target-descriptions. These .dat
files are used by GDBserver ports that still use static target
descriptions.
These .dat files are generated from corresponding .xml files in the
features directory. And since the corresponding .xml files for these
arm .dat files don't exist anymore, it is impossible to re-generated
them. If you delete these .dat files and type "make" in the features
directory, you'll get:
make: *** No rule to make target '../regformats/arm/arm-with-iwmmxt.dat', needed by 'all'. Stop.
So it removes the entries in the `WHICH` variable of
gdb/features/Makefile.
Finally, it removes the rule in gdbserver/Makefile to generate .cc files
from `../gdb/regformats/arm/%.dat`.

This changes the gdbserver build to use the gdbsupport that was built
for gdb.
gdbserver and gdbreplay now must use WIN32APILIBS (aka -lws2_32).
Before this change, gdbserver did not define USE_WIN32API when
building gdbsupport, but now this is always done.

gdbserver uses gdb's alloc.c, and this in turn can include headers
from intl via gdbsupport/gdb_locale.h. This can cause build failures
in some situations, for example if you build gdb and gdbserver on
mingw.
This patch restores the gdbsupport dependency on intl, and changes
gdbserver to use ZW_GNU_GETTEXT_SISTER_DIR. This fixes this build
problem.

I noticed gdbserver's Makefile doesn't have a mostlyclean target. I
use this sometimes, so this patch adds it. Adding it as a synonym of
"clean" seemed to make sense, given the contents of that rule.

2020-02-21 Tom Tromey <tom@tromey.com>
* Makefile.in (mostlyclean): New target.
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.

This changes gdbserver so that it no longer builds its own gnulib and
libiberty. Instead, it now relies on the ones that were already built
at the top level.
gdbsupport is still built specially for gdbserver. This is more
complicated and will be tackled in a subsequent patch.

For the same reasons outlined in the previous patch, this patch renames
gdbserver source files to .cc.
I have moved the "-x c++" switch to only those rules that require it.
gdbserver/ChangeLog:
* Makefile.in: Rename source files from .c to .cc.
* %.c: Rename to %.cc.
* configure.ac: Rename server.c to server.cc.
* configure: Re-generate.
This patch renames the .c source files in gdbsupport to .cc.
In the gdb directory, there is an argument against renaming the source
files, which is that it makes using some git commands more difficult to
do archeology. Some commands have some kind of "follow" option that
makes git try to follow renames, but it doesn't work in all situations.
Given that we have just moved the gdbsupport directory, that argument
doesn't hold for source files in that directory. I therefore suggest
renaming them to .cc, so that they are automatically recognized as C++
by various tools and editors.
The original motivation behind this is that when building gdbsupport
with clang, I get:
CC agent.o
clang: error: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Werror,-Wdeprecated]
In the gdb/ directory, we make clang happy by passing "-x c++". We
could do this in gdbsupport too, but I think that renaming the files is
a better long-term solution.
gdbserver still does its own build of gdbsupport, so a few changes in
its Makefile are necessary.
gdbsupport/ChangeLog:
* Makefile.am: Rename source files from .c to .cc.
(CC, CFLAGS): Don't override.
(AM_CFLAGS): Rename to ...
(AM_CXXFLAGS): ... this.
* Makefile.in: Re-generate.
* %.c: Rename to %.cc.
gdbserver/ChangeLog:
* Makefile.in: Rename gdbsupport source files from .c to .cc.
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.
