This patch replaces usage of target descriptions in ARC, where the whole
description is fixed in XML, with new target descriptions where XML describes
individual features, and GDB assembles those features into actual target
description.
v2:
Removed arc.c from ALLDEPFILES in gdb/Makefile.in.
Removed vim modeline from arc-tdep.c to have it in a separate patch.
Removed braces from one line "if/else".
Undid the type change for "jb_pc" (kept it as "int").
Joined the unnecessary line breaks into one line.
No more moving around arm targets in gdb/features/Makefile.
Changed pattern checking for ARC features from "arc/{aux,core}" to "arc/".
v3:
Added include gaurds to arc.h.
Added arc_read_description to _create_ target descriptions less.
v4:
Got rid of ARC_SYS_TYPE_NONE.
Renamed ARC_SYS_TYPE_INVALID to ARC_SYS_TYPE_NUM.
Fixed a few indentations/curly braces.
Converted arc_sys_type_to_str from a macro to an inline function.

Since this file contains things that apply not only to Cygwin binaries,
but also to non-Cygwin Windows binaries, I think it would make more
sense for it to be called i386-windows-tdep.c. It is analogous to
amd64-windows-tdep.c, which we already have.
gdb/ChangeLog:
* i386-cygwin-tdep.c: Rename to...
* i386-windows-tdep.c: ... this.
* Makefile.in (ALL_TARGET_OBS): Rename i386-cygwin-tdep.c to

GDB currently uses the "Cygwin" OS ABI (GDB_OSABI_CYGWIN) for everything
related to Windows. If you build a GDB for a MinGW or Cygwin target, it
will have "Cygwin" as the default OS ABI in both cases (see
configure.tgt). If you load either a MinGW or Cygwin binary, the
"Cygwin" OS ABI will be selected in both cases.
This is misleading, because Cygwin binaries are a subset of the binaries
running on Windows. When building something with MinGW, the resulting
binary has nothing to do with Cygwin. Cygwin binaries are only special
in that they are Windows binaries that link to the cygwin1.dll library
(if my understanding is correct).
Looking at i386-cygwin-tdep.c, we can see that GDB does nothing
different when dealing with Cygwin binaries versus non-Cygwin Windows
binaries. However, there is at least one known bug which would require
us to make a distinction between the two OS ABIs, and that is the size
of the built-in "long" type on x86-64. On native Windows, this is 4,
whereas on Cygwin it's 8.
So, this patch adds a new OS ABI, "Windows", and makes GDB use it for
i386 and x86-64 PE executables, instead of the "Cygwin" OS ABI. A
subsequent patch will improve the OS ABI detection so that GDB
differentiates the non-Cygwin Windows binaries from the Cygwin Windows
binaries, and applies the "Cygwin" OS ABI for the latter.
The default OS ABI remains "Cygwin" for the GDBs built with a Cygwin
target.
I've decided to split the i386_cygwin_osabi_sniffer function in two,
I think it's cleaner to have a separate sniffer for Windows binaries and
Cygwin cores, each checking one specific thing.
gdb/ChangeLog:
* osabi.h (enum gdb_osabi): Add GDB_OSABI_WINDOWS.
* osabi.c (gdb_osabi_names): Add "Windows".
* i386-cygwin-tdep.c (i386_cygwin_osabi_sniffer): Return
GDB_OSABI_WINDOWS when the binary's target is "pei-i386".
(i386_cygwin_core_osabi_sniffer): New function, extracted from
i386_cygwin_osabi_sniffer.
(_initialize_i386_cygwin_tdep): Register OS ABI
GDB_OSABI_WINDOWS for i386.
* amd64-windows-tdep.c (amd64_windows_osabi_sniffer): Return
GDB_OSABI_WINDOWS when the binary's target is "pei-x86-64".
(_initialize_amd64_windows_tdep): Register OS ABI GDB_OSABI_WINDOWS
for x86-64.
* configure.tgt: Use GDB_OSABI_WINDOWS as the default OS ABI
when the target matches '*-*-mingw*'.
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.

Here's the patch corresponding to the Solaris 10 obsoletion announcement
https://sourceware.org/ml/gdb/2019-10/msg00008.html
Right now it doesn't remove any code, but obviates the need to test on
that ancient platform. Besides, some of the patches I have in my queue
would require different solutions for Solaris 10 and 11.
There are a few comment-only references that I've kept since they are
still correct as is, even when GDB doesn't support Solaris 10 any
longer. The only code fragment I've left in is support for
/proc/<pid/path/a.out in procfs.c (procfs_target::pid_to_exec_file):
while current Solaris 11 updates provide /proc/<pid>/execname, that
wasn't present in Solaris 11.0 and still isn't in current Illumos and I
didn't want to make live harder for them.
Tested on i386-pc-solaris2.10 (obsolete configuration rejected) and
x86_64-pc-linux-gnu x sparc64-solaris2.10 (likewise)
resp. x86_64-pc-linux-gnu x sparcv9-solaris2.11 (still builds; I'm using
the sparcv9 form for 64-bit SPARC customary on Solaris in the
MAINTAINERS file now).

This commit adds target description support for riscv.
I've used the split feature approach for specifying the architectural
features, and the CSR feature is auto-generated from the riscv-opc.h
header file.
If the target doesn't provide a suitable target description then GDB
will build one by looking at the bfd headers.
This commit does not implement target description creation for the
Linux or FreeBSD native targets, both of these will need to add
read_description methods into their respective target classes, which
probe the target features, and then call
riscv_create_target_description to build a suitable target
description. Until this is done Linux and FreeBSD will get the same
default target description based on the bfd that bare-metal targets
get.
I've only added feature descriptions for 32 and 64 bit registers, 128
bit registers (for RISC-V) are not supported in the reset of GDB yet.
This commit removes the special reading of the MISA register in order
to establish the target features, this was only used for figuring out
the f-register size, and even that wasn't done consistently. We now
rely on the target to tell us what size of registers it has (or look
in the BFD as a last resort). The result of this is that we should
now support RV64 targets with 32-bit float, though I have not
extensively tested this combination yet.

On ARM, PikeOS does not support hardware single step, causing various
semi-random errors when trying to next/step over some user code. So
this patch changes this target to use software-single-step instead.
The challenge is that, up to now, the PikeOS target was in all respects
identical to a baremetal target as far as GDB was concerned, meaning
we were using the baremetal osabi for this target too. This is no longer
possible, and we need to introduce a new OSABI variant. Unfortunately,
there isn't anything in the object file that would allow us to
differentiate between the two platforms. So we have to rely on a
heuristic instead, where we look for some known symbols that are
required in a PikeOS application (these symbols are expected to be
defined by the default linker script, and correspond to routines used
to allocate the application stack).
For the long run, the hope is that the stub implementation provided
by PikeOS is enhanced so that it includes vContSupported+ to the
$qSupported query, and then that the reply to the "vCont?" query
only return support for "continue" operations (thus exclusing "step"
operations). We could then use that information to reliably determine
at connection time that the target does not support single-stepping
and therefore automatically turn software single-stepping automatically
based on it.

Share target description declarations and selection among ppc linux
native targets, core files, gdbserver and IPA.
To avoid complicated define guards, gdbserver and IPA now have
declarations for all descriptions, including 64-bit generated
descriptions when compiled in 32-bit mode. These have always been
linked into the gdbserver and IPA binaries. Because they might be
uninitialized, the selection function checks that the selected
description is initialized.

We get this error when doing a build with a single amd64 target (the
default when doing just ./configure on x86-64 GNU/Linux):
/home/simark/src/binutils-gdb/gdb/i386-tdep.c:4431: error: undefined reference to 'x86_in_indirect_branch_thunk(unsigned long, char const**, int, int)'
/home/simark/src/binutils-gdb/gdb/amd64-tdep.c:3045: error: undefined reference to 'x86_in_indirect_branch_thunk(unsigned long, char const**, int, int)'
The problem is that commit
1d509aa625 ("infrun: step through indirect branch thunks")
missed adding x86-tdep.o to the list of object file included in an amd64
or i386 build. The problem is not seen with --enable-targets=all
because that file is included in ALL_TARGET_OBS.
Built-tested using:
* --host=x86_64-pc-linux-gnu --target=x86_64-pc-linux-gnu

This commit introduces basic support for baremetal RiscV as a GDB
target. This target is currently only tested against the RiscV software
simulator, which is not included as part of this commit. The target has
been tested against the following RiscV variants: rv32im, rv32imc,
rv32imf, rv32imfc, rv64im, rv64imc, rv64imfd, rv64imfdc.
Across these variants we pass on average 34858 tests, and fail 272
tests, which is ~0.8%.
The RiscV has a feature of its ABI where structures with a single
floating point field, a single complex float field, or one float and
one integer field are treated differently for argument passing. The
new test gdb.base/infcall-nested-structs.exp is added to cover this
feature. As passing these structures should work on all targets then
I've made the test as a generic one, even though, for most targets,
there's probably nothing special about any of these cases.

Currently all target dependent code for s390 is in one file,
s390-linux-tdep.c. This includes code general for the architecture as
well as code specific for uses in GNU/Linux (user space). Up until now
this was OK as GNU/Linux was the only supported OS. In preparation to
support the new Linux kernel 'OS' split up the existing s390 code into a
general s390-tdep and a GNU/Linux-specific s390-linux-tdep.
Note: The record-replay feature will be moved in a separate patch. This
is simply due to the fact that the combined patch would be too large for
the mailing list. This requires setting the process_record hook during
OSABI init to keep the code bisectable. The patch moving record-replay
cleans up this hack.

This patch prepares the current GDB port of the OpenRISC processor from
https://github.com/openrisc/binutils-gdb for upstream merging.
Testing has been done with a cgen sim provided in a separate patch. This
has been tested with 2 toolchains. GCC [1] 5.4.0 from the OpenRISC
project with Newlib [2] and GCC 5.4.0 with Musl [3] 1.1.4.
It supports or1knd (no delay slot target).
The default target is or1k (with delay slot).
You can change the target arch with:
(gdb) set architecture or1knd
The target architecture is assumed to be or1knd

For some reason symfile-mem.o is not included in the configuration for
"s390*-*-linux*". It was added to the configuration of most GNU/Linux
targets with a patch from Andrew Cagney:
"Add symfile-mem to all linux targets" --
https://sourceware.org/ml/gdb-patches/2005-02/msg00053.html
But the s390 target was overlooked at that time. Thus the command
"add-symbol-file-from-memory" is missing and VDSO symbols are not loaded.
This is fixed.
gdb/ChangeLog:
* configure.tgt (s390*-*-linux*): Add symfile-mem.o.
Support for collecting and supplying general purpose and floating
point registers is provided along with signal frame unwinding. While
FreeBSD/arm kernels do populate NT_FPREGSET notes, they are always
zero-filled, so this implementation ignores them. Recent FreeBSD/arm
kernels generate NT_ARM_VFP notes which are used to supply
floating-point registers. As with Linux, the AT_HWCAP feature flags
are used to determine the correct target description.

This patch moves aarch64-insn.o to arch/aarch64-insn.o. Then, all

Nowadays, there are much duplications in configure.tgt to update
gdb_target_obs, some cpu specific object files are added to gdb_target_obs
to some different target triplets of the same cpu. The same problem
exists for os specific object files too. It is fragile to update them,
and build with all targets enabled doesn't find the problem.
This patch splits the gdb_target_obs update to three steps, cpu steps, os
steps, and the rest.
I tested this patch by build gdb for each different target triplets

Set $cpu_obs and $os_obs.
Nowadays, GDB build tree is almost flat, but source tree isn't. We
have arch/ nat/ target/ common/ cli/ mi/ tui/ python/ guile/ directories.
We need to some rules in Makefile for source files in different source
directories, like,
# Rules for compiling .c files in the various source subdirectories.
%.o: ${srcdir}/arch/%.c
$(COMPILE) $<
$(POSTCOMPILE)
%.o: ${srcdir}/nat/%.c
$(COMPILE) $<
$(POSTCOMPILE)
so we should take care of some special case that files' base name is the
same, like,
# Specify an explicit rule for gdb/common/agent.c, to avoid a clash with the
# object file generate by gdb/agent.c.
common-agent.o: $(srcdir)/common/agent.c
$(COMPILE) $(srcdir)/common/agent.c
$(POSTCOMPILE)
As we add more and more files in different directories, it becomes tricky
to name files, because we need take this into account.
This patch takes the first step toward "Replicate src dir in build dir",
that is, we create arch/ directory in buildtree, and put amd64.o there
as an example. Dependency tracking is updated for files with directory
name. Currently, when we build amd64.o,
"-c -o amd64.o -MT amd64.o -MMD -MP -MF .deps/amd64.Tpo"
with this patch applied, it becomes,
"-c -o arch/amd64.o -MT arch/amd64.o -MMD -MP -MF arch/.deps/amd64.o.Tpo"
"make clean" removes the object files, and "make distclean" removes .deps
additionally. configure file create .deps directory in each of
CONFIG_SRC_SUBDIR, and pass it to Makefile.in, so that "make clean" and
"make distclean" can remove stuffs there.
If people agree with this change, I'll add more directories to
CONFIG_SRC_SUBDIR.

Given that GCC has obsoleted/removed support for Solaris 9 in GCC 4.9/5 in 2013:
https://gcc.gnu.org/gcc-4.9/changes.htmlhttps://gcc.gnu.org/ml/gcc-patches/2013-05/msg00728.html
and the last gdb version that can be compiled with gcc 4.9 is 7.12.1 only when
configured with --disable-build-with-cxx, it's time to obsolete/remove support
for Solaris < 10.
This patch does this, simplifying configure.nat along the way (only a single
sol2 configuration with variants for i386 and sparc).
Some configure checks for older Solaris versions can go, too, and the check
for libthread_db.so.1 removed:
* Since Solaris 10, dlopen has moved to libc and libdl.so is just a
filter on ld.so.1, so no need to check.
* $RDYNAMIC is already handled above (and is a no-op with Solaris ld
anyway).
Both proc-service.c and sol-thread.c lose support for (Solaris-only)
PROC_SERVICE_IS_OLD.
The attached revised patch has been tested on sparcv9-sun-solaris2.10,
sparcv9-sun-solaris2.11.4, amd64-pc-solaris2.10, amd64-pc-solaris2.11.4,
and x86_64-pc-linux-gnu.
I've also started an i386-pc-solaris2.9 build to check that it really
stops as expected.

I posit that this makes them easier to find.
The other day while working on the wchar_t patch, I had a bit of
trouble finding the DJGPP/go32 tdep bits. My initial reaction was
looking for a go32-specific tdep file, but there's none.
Confirmed that a --host=i586-pc-msdosdjgpp GDB still builds
successfully and includes the i386-go32-tdep.o object.
Confirmed that an --enable-targets=all build of GDB on x86-64
GNU/Linux includes the DJGPP/go32 bits too.
gdb/ChangeLog:
2017-04-12 Pedro Alves <palves@redhat.com>
* Makefile.in (ALL_TARGET_OBS): Add i386-go32-tdep.o.

declarations.
The bsd-uthread target supports an old thread library ("libc_r") that
was last included in FreeBSD release 6.4 released in 2008. However,
this library has not been used as the default library since FreeBSD
5.0 (2003) and 4.11 (2005). Thread support for modern FreeBSD binaries
is provided via "normal" LWP support in core files and the native
FreeBSD target.
gdb/ChangeLog:
* amd64-fbsd-tdep.c: Remove "bsd-uthread.h" include.

(x86_64-*-freebsd*): Remove bsd-uthread.o.
(fbsd-nat.c): Update comment.
* i386-fbsd-tdep.c: Remove "bsd-uthread.h" include.
(i386fbsd_jmp_buf_reg_offset): Remove.
(i386fbsd_supply_uthread): Remove function.
(i386fbsd_collect_uthread): Remove function.
(i386fbsd_init_abi): Don't set bsd-uthread callbacks.
FreeBSD last shipped a release for Alpha (6.3) in 2008.
This also removes support for GNU/kFreeBSD on Alpha.
gdb/ChangeLog:
* Makefile.in (ALL_64_TARGET_OBS): Remove alpha-fbsd-tdep.o.
(ALLDEPFILES): Remove alpha-fbsd-tdep.c
* NEWS: Mention that support for FreeBSD/alpha was removed.
* alpha-fbsd-tdep.c: Delete file.
* config/alpha/fbsd.mh: Delete file.
* configure.host: Delete alpha*-*-freebsd* and
alpha*-*-kfreebsd*-gnu.
* configure.tgt: Delete alpha*-*-freebsd* and
alpha*-*-kfreebsd*-gnu.
This has been tested for the n64 and o32 ABIs. Signal frame unwinders for
both ABIs are provided. FreeBSD/mips requires custom linkmap offsets since
it contains an additional l_off member in 'struct link_map' that other
FreeBSD platforms do not have. Support for collecting and supplying
general purpose and floating point register sets are provided. Common
routines for working with native format register sets are exported for
use by the native target.
gdb/ChangeLog:
* Makefile.in (ALL_TARGET_OBS): Add mips-fbsd-tdep.o.
(ALLDEPFILES): Add mips-fbsd-tdep.c.
* NEWS: Mention new FreeBSD/mips target.
* configure.tgt: Add mips*-*-freebsd*.
* mips-fbsd-tdep.c: New file.
* mips-fbsd-tdep.h: New file.
gdb/doc/ChangeLog:
* gdb.texinfo (Contributors): Add SRI International and University
of Cambridge for FreeBSD/mips.
