Rainer Orth dae8b3eb23 Obsolete Solaris 10 support
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).

	* NEWS (Changes since GDB 8.3): Document Solaris 10 removal.
	* configure.host: Mark *-*-solaris2.10* obsolete.
	* configure.tgt: Mark Solaris < 11 obsolete.
	* MAINTAINERS (Target Instruction Set Architectures) <sparc>:
	Update target triplet.

- Support for the spu-*-* target
- Support for native stand-alone SPU debugging
- Support for integrated debugging of combined PPU/SPU applications
- Remote debugging (gdbserver) support for all the above.

The patch also removes the TARGET_OBJECT_SPU target object type,
as this is available only on Cell/B.E. targets, including
- Native Linux support
- Core file support (including core file generation)
- Remote target support, including removal of the qXfer:spu:read
  and qXfer:spu:write remote protocal packets and associated
  support in gdbserver.

Stafford Horne 42e151bf4c gdb/or1k: Add linux debugging support
Up until now OpenRISC GDB only has supported bare metal debugging.  This
patch adds linux userspace debugging and core dump analysis support.

against musl libc.

Andrew Burgess b5ffee3181 gdb/riscv: Add target description support
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.

Jerome Guitton e1c3a37375 arm-pikeos: software single step
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.

        * defs.h (enum gdb_osabi): Add GDB_OSABI_PIKEOS.
        * osabi.c (gdb_osabi_names): Add name for GDB_OSABI_PIKEOS.

Pedro Franco de Carvalho bd64614eb7 [PowerPC] Consolidate linux target description selection
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.

Simon Marchi eda4efb127 Add x86-tdep.o to i386/amd64 target build
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

Andrew Burgess dbbb1059e6 gdb: Initial baremetal riscv support
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.

Philipp Rudo d6e5894564 s390: Split up s390-linux-tdep.c into two files
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.

Franck Jullien a994fec4f8 gdb: Add OpenRISC or1k and or1knd target support
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

Andreas Arnez 336ef6d22a S390: Add symfile-mem
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.

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.

Yao Qi d97987e219 Share code updating gdb_target_obs
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.

Yao Qi f38307f593 [RFC] Replicate src dir in build dir
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.

Rainer Orth 281c444773 Remove support for Solaris < 10 (PR gdb/22185)
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.html
    https://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.

Pedro Alves 8f10c93233 gdb: Move DJGPP/go32 bits to their own tdep file
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

this library has not been used as the default library since FreeBSD

Simon Marchi 03b62bbbce Normalize names of some source files
Most tdep/nat files are named:

  <cpu>-<os>-tdep.c
  <cpu>-<os>-nat.c

A few files do not respect this scheme.  This patch renames them so that
they are consistent with the rest of the files.  It builds fine with
--enable-targets=all, but that doesn't test the nat files.  I can only
hope that my grep skill is good enough.

Yao Qi 78836e904d Don't configure gdb for vxworks target
VxWorks support was removed in 2004.

commit e84ecc995d
Author: Andrew Cagney <cagney@redhat.com>
Date:   Sat Nov 13 23:10:02 2004 +0000

    2004-11-13  Andrew Cagney  <cagney@gnu.org>

        * configure.tgt: Delete i[34567]86-*-vxworks*, m68*-netx-*,
        m68*-*-vxworks*, mips*-*-vxworks*, powerpc-*-vxworks*, and
        sparc-*-vxworks*.
        * NEWS: Mention that vxworks was deleted.

This patch adds *-*-vxworks* in a list of targets GDB doesn't
support.

Anton Kolesov 4a2f482690 arc: Add support for Newlib
Add support for Newlib as an OS/ABI.  The only thing that is specific to it
relatively to "generic" baremetal target is location of PC register in jump
buffer for longjump support.

Sniffer uses .ivt section to decide if ELF file is for ARC Newlib or not.

gdb/ChangeLog:

	* arc-newlib-tdep.c: New file.
	* configure.tgt: Add newlib support for ARC.

Anton Kolesov ad0a504f7e arc: New Synopsys ARC port
ARC is a family of licensable processors developed by Synopsys.

This is an initial patch that doesn't yet support some of the features, that
are already available in Synopsys' fork of GDB, namely:

  * longjmp support
  * signal frame handling
  * prologue analysis
  * Linux targets support
  * native Linux support

ARC cores are configurable and extensible, which means from debugger
perspective that some registers and debug capabilities are optional, therefore
it is up to the GDB stub to determine exact list of register available on
target and supply it to GDB via XML target descriptions.  List of registers
that is known to GDB and is required is intentionally kept small to simplify
requirements to GDB stub and implementation of a GDB client.

gdb/ChangeLog:

	* Makefile.in (ALL_TARGET_OBS): Add arc-tdep.o.
	(HFILES_NO_SRCDIR): Add arc-tdep.h.
	(ALLDEPFILES): Add arc-tdep.c.
	* NEWS: Mention new ARC port.
	* configure.tgt: Add ARC.
	* arc-tdep.c: New file.
	* arc-tdep.h: New file.
	* features/Makefile (XMLTOC): Add arc-v2.xml and arc-arcompact.xml.

	* features/arc-v2.c: New file (generated).
	* features/arc-arcompact.xml: New file.
	* features/arc-arcompact.c: New file (generated).

gdb/doc/ChangeLog:

	* gdb.texinfo (Embedded Processors): Document ARC.
	(Synopsys ARC): New section.
	(Standard Target Features): Document ARC features.
	(ARC Features): New section.
