[PATCH] configure: Always add pre-installed header directories to search path
configure script was adding the target directory flags, including the
'-B' flags for the executable prefix and the '-isystem' flags for the
pre-installed header directories, to the target flags only for
non-Canadian builds under the premise that the host binaries under the
executable prefix will not be able to execute on the build system for
Canadian builds.
While that is true for the '-B' flags specifying the executable prefix,
the '-isystem' flags specifying the pre-installed header directories are
not affected by this and do not need special handling.
This patch updates the configure script to always add the 'include' and
'sys-include' pre-installed header directories to the target search
path, in order to ensure that the availability of the pre-installed
header directories in the search path is consistent across non-Canadian
and Canadian builds.
When '--with-headers' flag is specified, this effectively ensures that
the libc headers, that are copied from the specified header directory to
the sys-include directory, are used by libstdc++.

config, toplevel, Darwin: Pass -B instead of -L to C++ commands.
Darwin from 10.11 needs embedded rpaths to find the correct libraries at
runtime. Recent increases in hardening have made it such that the dynamic
loader will no longer fall back to using an installed libstdc++ when the
(new) linked one is not found. This means we fail configure tests (that
should pass) for runtimes that use C++.
We can resolve this by passing '-B' to the C++ command lines instead of '-L'
(-B implies -L on Darwin, but also causes a corresponding embedded rpath).

GCN, nvptx: Don't default-disable libstdc++ build
In addition to making libstdc++ itself available, this, via enabling
'build-gcc/*/libstdc++-v3/scripts/testsuite_flags', in particular also makes
the standard C++ headers available to 'make check-gcc-c++'. With that, there
are a lot of FAIL/UNRESOLVED -> PASS progressions, where we previously ran
into, for example:
FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for errors, line 6)
FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for excess errors)
Excess errors:
[...]/gcc/testsuite/g++.dg/coroutines/coro.h:132:10: fatal error: cstdlib: No such file or directory
Similarly, there are a lot of FAIL/UNRESOLVED -> UNSUPPORTED "progressions" due
to 'sorry, unimplemented: exception handling not supported'.
The 'make check-target-libstdc++-v3' results don't look too bad, either.
This also reverts Subversion r221362
(Git commit d94fae044da071381b73a2ee8afa874b14fa3820) "No libstdc++ for nvptx",
and commit 2f4f3c0e9345805160ecacd6de527b519a8c9206 "No libstdc++ for GCN".
With libstdc++ now available, libgrust gets enabled, which we in turn again
have to disable, for 'sorry, unimplemented: exception handling not supported'
reasons.

cobol: Fix up libgcobol configure [PR119216]
Sorry, seems I've screwed up the earlier libgcobol/configure.tgt change.
Looking in more detail, the way e.g. libsanitizer/configure.tgt works is
that it is sourced twice, once at toplevel and there it just sets
UNSUPPORTED=1 for fully unsupported triplets, and then inside of
libsanitizer/configure where it decides to include or not include the
various sublibraries depending on the *_SUPPORTED flags.
So, the following patch attempts to do the same for libgcobol as well.
The BIULD_LIBGCOBOL automake conditional was unused, this patch guards it
on LIBGCOBOL_SUPPORTED as well and guards with it
toolexeclib_LTLIBRARIES = libgcobol.la
Also, AM_CFLAGS has been changed to AM_CXXFLAGS as there are just C++
sources in the library.

We have a discrepancy with 64-bit BFD handling across our component
subdirectories leading to link failures such as:
ld: ../opcodes/.libs/libopcodes.a(disassemble.o): in function `disassembler': disassemble.c:(.text+0x65): undefined reference to `print_insn_alpha'
ld: disassemble.c:(.text+0x105): undefined reference to `print_insn_ia64'
ld: disassemble.c:(.text+0x11d): undefined reference to `print_insn_loongarch'
ld: disassemble.c:(.text+0x1a1): undefined reference to `print_insn_big_mips'
[...]
with some configurations having a 32-bit host and 64-bit BFD, such as:
`--host=i386-linux-gnu --target=riscv64-linux-gnu --enable-targets=all'.
This is ultimately due to how 64-bit BFD is enabled for bfd/ itself and
other subdirectorses and has been a regression from commit 1d5269c994
("unify 64-bit bfd checks").
For bfd/ the BFD_64_BIT autoconf macro from config/bfd64.m4 is used
combined with this logic in bfd/configure.ac:
case ${host64}-${target64}-${want64} in
*true*)
wordsize=64
bfd64_libs='$(BFD64_LIBS)'
all_backends='$(BFD64_BACKENDS) $(BFD32_BACKENDS)'
[...]
;;
false-false-false)
wordsize=32
all_backends='$(BFD32_BACKENDS)'
;;
esac
where the value of ${wordsize} switches between 32-bit and 64-bit BFD
via these pieces:
#define BFD_ARCH_SIZE @wordsize@
and:
#if BFD_ARCH_SIZE >= 64
#define BFD64
#endif
in bfd/bfd-in.h, which ultimately becomes a part of "bfd.h".
Then ${host64} is determined in bfd/configure.ac from the host's word
size, via the host's pointer size:
if test "x${ac_cv_sizeof_void_p}" = "x8"; then
host64=true
fi
And ${target64} is determined in bfd/configure.ac from the target's word
size:
if test ${target_size} = 64; then
target64=true
fi
Where multiple targets have been requested with `--enable-targets=all'
the presence of any 64-bit target will set "true" here.
Finally ${want64} is set according to `--enable-64-bit-bfd' user option
with an arrangement involving BFD_64_BIT:
BFD_64_BIT
if test $enable_64_bit_bfd = yes ; then
want64=true
else
want64=false
fi
which also, redundantly, checks and sets its result upon the host's word
size. Lastly ${want64} is also selectively set by target fragments in
bfd/config.bfd, which mostly if not completely overlaps with ${target64}
setting as described above.
Conversely other subdirectories only rely on BFD_64_BIT, so they fail to
notice that BFD is 64-bit and do not enable their 64-bit handling where
the host requested is 32-bit and 64-bit BFD has been enabled other than
with `--enable-64-bit-bfd'. One consequence is opcodes/disassemble.c
enables calls to its numerous own 64-bit backends by checking the BFD64
macro from "bfd.h", however does not actually enable said backends in
its Makefile. Hence the link errors quoted above.
Address the problem then by moving the `--enable-64-bit-bfd' option back
to bfd/configure.ac and remove the call to BFD_64_BIT from there and
then rewrite the macro in terms of checking for the presence of BFD64
macro in "bfd.h", which is the canonical way of determining whether BFD
is 64-bit or not.
Rather than running `grep' directly on ../bfd/bfd-in3.h as the opcodes/
fragment used to before the problematic commit:
if grep '#define BFD_ARCH_SIZE 64' ../bfd/bfd-in3.h > /dev/null; then
run the preprocessor on "bfd.h", which allows to invoke the macro from
configure.ac files placed in subdirectories located at deeper levels, by
relying on the preprocessor's search path.
This requires however that the invokers rely on `all-bfd' rather than
`configure-bfd' for their `configure' invocation stage, because "bfd.h"
is made by `make all' rather than `configure' in bfd/.
Do not cache the result of this check however, as reconfiguring a tree
such as to flip `--enable-64-bit-bfd' on or to change a secondary target
may affect BFD64 and we have no access to information about secondary
targets in BFD_64_BIT.
Also remove the ENABLE_BFD_64_BIT automake conditional, as it's not used
anywhere.
Last but not least remove the hack from gdb/configure.ac to fail builds
for `mips*-*-*' hosts where `--enable-targets=all' has been requested,
but `--enable-64-bit-bfd' has not as it's no longer needed. Such builds
complete successfully now, having enabled 64-bit BFD implicitly.

Make gdbserver's build system locate libiconv when building for Linux.
Commit 07b3255c3b ("Filter invalid encodings from Linux thread names")
make libiconv madantory for building gdbserver on Linux.
While trying to cross-compile gdb for xtensa-fsf-linux-uclibc (with a
toolchain generated with crosstool-ng), I got:
/home/smarchi/src/binutils-gdb/gdbserver/linux-low.cc:48:10: fatal error: iconv.h: No such file or directory
48 | #include <iconv.h>
| ^~~~~~~~~
I downloaded GNU libiconv, built it for that host, and installed it in
an arbitrary directory. I had to modify the gdbserver build system to
locate libiconv and use it, the result is this patch.
I eventually found that crosstool-ng has a config option to make uclibc
provide an implementation of iconv, which is of course much easier. But
given that this patch is now written, I think it would be worth merging
it, it could help some people who do not have iconv built-in their libc
in the future (and may not have the luxury of rebuilding their libc like
I do).
Using AM_ICONV in configure.ac adds these options for configure (the
same we have for gdb):
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
--with-libiconv-type=TYPE type of library to search for (auto/static/shared)
It sets the `LIBICONV` variable with whatever is needed to link with
libiconv, and adds the necessary `-I` flag to `CPPFLAGS`.
To avoid unnecessarily linking against libiconv on hosts that don't need
it, set `MAYBE_LIBICONV` with the contents of `LIBICONV` only if the
host is Linux, and use `MAYBE_LIBICONV` in `Makefile.in`.
Since libiconv is a hard requirement for Linux hosts, error out if it is
not found.
The bits in acinclude.m4 are similar to what we have in
gdb/acinclude.m4.
Update the top-level build system to support building against an in-tree
libiconv (I did not test this part though). Something tells me that the
all-gdbserver dependency on all-libiconv is unnecessary, since there is
already a dependency of configure-gdbserver on all-libiconv (and
all-gdbserver surely depends on configure-gdbserver). I just copied
what's done for GDB though.
ChangeLog:
* Makefile.def: Add configure-gdbserver and all-gdbserver
dependencies on all-libiconv.
* Makefile.in: Re-generate.

Makefile.tpl: Avoid race condition in generating site.exp from the top level
A command like "make -j 2 check-gcc-c check-gcc-c++" run in the top level of
a fresh build directory does not work reliably. That will spawn two
independent make processes inside the "gcc" directory, and each of those
will attempt to create site.exp if it doesn't exist and will interfere with
each other, producing often a corrupted or empty site.exp. Resolve that by
making these targets depend on a new phony target which makes sure site.exp
is created first before starting the recursive makes.

Config,Darwin: Allow for configuring Darwin to use embedded runpath.
Recent Darwin versions place contraints on the use of run paths
specified in environment variables. This breaks some assumptions
in the GCC build.
This change allows the user to configure a Darwin build to use
'@rpath/libraryname.dylib' in library names and then to add an
embedded runpath to executables (and libraries with dependents).
The embedded runpath is added by default unless the user adds
'-nodefaultrpaths' to the link line.
For an installed compiler, it means that any executable built with
that compiler will reference the runtimes installed with the
compiler (equivalent to hard-coding the library path into the name
of the library).
During build-time configurations any "-B" entries will be added to
the runpath thus the newly-built libraries will be found by exes.
Since the install name is set in libtool, that decision needs to be
available here (but might also cause dependent ones in Makefiles,
so we need to export a conditional).
This facility is not available for Darwin 8 or earlier, however the
existing environment variable runpath does work there.
We default this on for systems where the external DYLD_LIBRARY_PATH
does not work and off for Darwin 8 or earlier. For systems that can
use either method, if the value is unset, we use the default (which
is currently DYLD_LIBRARY_PATH).

The D front-end is now itself written in D, in order to build GDC, you
will need a working GDC compiler (GCC version 9.1 or later).
GCC changes:
- Add support for bootstrapping the D front-end.
These add the required components in order to have a D front-end written
in D itself. Because the compiler front-end only depends on the core
runtime modules, only libdruntime is built for the bootstrap stages.
D front-end changes:
- Import dmd v2.098.0-beta.1.
Druntime changes:
- Import druntime v2.098.0-beta.1.
Phobos changes:
- Import phobos v2.098.0-beta.1.

The latest versions of Darwin on the Aarch64 platform mandate PIE executables.
On x86_64 it remains optional, but produces tool warnings after Darwin20, so
we default to PIE executables there too.
All (non-PowerPC) 64b Darwin platforms mandate PIC code and therefore force
host_shared on (we issue a diagnostic if the user tries to configure them
non-shared).
However, this also means we cannot test the host_shared setting independently
of the host_pie setting so that the logic for setting PICFLAG must be amended
for Darwin.
For Darwin versions required to have PIE executables, in the event that the
user tries to configure these as --disable-host-pie, we issue a warning and
override the setting. These versions must also switch host_pie on even if it
is not given in the configure line. To cater for this we pass the current
value of host_pie, as determined by top-level configure, to the GCC configure.

* Makefile.def: Pass the enable-host-pie value to GCC configure.
* configure.ac: Adjust the logic for shared and PIE host flags to

If we are building PIC/PIE host executables, and we are building dependent
libs (e.g. GMP) in-tree those libs need to be configured to generate PIC code.

* configure.ac (host_libs_picflag): New configure variable set to

We do not use the shared libffi libraray, nor do we install it.
However, on at least Darwin, the shared version will be picked
up for testing, so it is preferrable not to build it.

This patch uses the toplevel configure parts for GMP/MPFR for
gdb. The only thing is that gdb now requires MPFR for building.
Before it was a recommended but not required library.
Also this allows building of GMP and MPFR with the toplevel
directory just like how it is done for GCC.
We now error out in the toplevel configure of the version
of GMP and MPFR that is wrong.
OK after GDB 13 branches? Build gdb 3 ways:
with GMP and MPFR in the toplevel (static library used at that point for both)
With only MPFR in the toplevel (GMP distro library used and MPFR built from source)
With neither GMP and MPFR in the toplevel (distro libraries used)

The linker merges all the input .sframe sections. When merging, the
linker verifies that all the input .sframe sections have the same
abi/arch.
The linker uses libsframe library to perform key actions on the
.sframe sections - decode, read, and create output data. This
implies buildsystem changes to make and install libsframe before
libbfd.
The linker places the output .sframe section in a new segment of its
own: PT_GNU_SFRAME. A new segment is not added, however, if the
generated .sframe section is empty.
When a section is discarded from the final link, the corresponding
entries in the .sframe section for those functions are also deleted.
The linker sorts the SFrame FDEs on start address by default and sets
the SFRAME_F_FDE_SORTED flag in the .sframe section.
This patch also adds support for generation of SFrame unwind
information for the .plt* sections on x86_64. SFrame unwind info is
generated for IBT enabled PLT, lazy/non-lazy PLT.
The existing linker option --no-ld-generated-unwind-info has been
adapted to include the control of whether .sframe unwind information
will be generated for the linker generated sections like PLT.
Changes to the linker script have been made as necessary.

libsframe is a library that allows you to:
- decode a .sframe section
- probe and inspect a .sframe section
- encode (and eventually write) a .sframe section.
This library is currently being used by the linker, readelf, objdump.
This library will also be used by the SFrame unwinder which is still
to be upstream'd.
The file include/sframe-api.h defines the user-facing APIs for decoding,
encoding and probing .sframe sections. A set of error codes together
with their error message strings are also defined.
Endian flipping is performed automatically at read and write time, if
cross-endianness is detected.

I'm not entirely sure why this is here since the sim doesn't use
anything from the gdb/ dir directly, and the commit that added it
included a bunch more changes and doesn't seem to call out this
dep specifically.
Since ld may depend on libctf (if present), and libctf may be relinked
by the installation process, libctf must be installed before ld is,
or the relink may fail if it calls on symbols or symbol versions that do
not exist in any libctf already present on the system. (If none is
present, the copy in the build tree will be automatically used, but
if one *is* present, it may take precedence and break things.)
(This is a maybe- dependency, so it will work even if libctf is
disabled.)

* Makefile.def: Add install-libctf dependency to install-ld.
* Makefile.in: Regenerated.
This introduces a new lookup testsuite under libctf, which operates by
compiling (with libtool) a "lookup" .c file that uses libctf to analyze
some other program, then compiling some number of test object files with
CTF and optionally linking them together and running the lookup program
on the test object files (or linked test binary), before diffing the
result much as run_dump_test does.
This lets us test the portions of libctf that are not previously
testable, notably the portions that do lookup on linked output and
that create dynamic dictionaries and then do lookup on them before
writing them out, something that is not tested by the ld-ctf testsuite
because the linker never does this.
A couple of simple tests are added: one testing the functionality of
enum lookups, and one testing that the recently-added commit adding
extra paranoia to incomplete type handling doesn't break linking and
that the result of the link is an (otherwise-impossible) array of
forward type in the shared CTF dict.

gnulib: Ensure all libraries are used when building gdb/gdbserver
We now get an error when, at the top level of the build tree, we do
'make distclean'.
The reason for this is that the gnulib directory is cleaned before the
gdb directory, cleaning gnulib deletes Makefile.gnulib.inc from the
gnulib build directory, which is currently pulled in by the gdb
Makefile.in using 'include'.
This commit adds a dependency between distclean-gnulib and both
distclean-gdb and distclean-gdbserver. This means that gdb and
gdbserver will be cleaned before gnulib, as a result the
Makefile.gnulib.inc file should exist when needed.
ChangeLog:
* Makefile.in: Rebuild.
* Makefile.def: Make distclean-gnulib depend on distclean-gdb and
distclean-gdbserver.
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.

This changes gdbsupport so that it no longer relies on BFD. This is a
precursor to making gdbserver use the already-built gdbsupport,
because building gdbserver should not require BFD to be built.
The most notable change here is that CORE_ADDR is always a 64-bit
type. This makes it so that gdb acts as if it were always built in
64-bit mode.

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.

This changes gdbserver so that it no longer builds its own gnulib and

at the top level.

complicated and will be tackled in a subsequent patch.

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.

This patch then adds a build system to gdbsupport and wires it into
the top level. Then it changes gdb to use the top-level build.
gdbserver, on the other hand, is not yet changed. It still does its
own build of gdbsupport.

This patch adds the CTF (Compact Ansi-C Type Format) support in gdb.
Two submissions on which this gdb work depends were posted earlier
in May:
* On the binutils mailing list - adding libctf which creates, updates,
reads, and manipulates the CTF data.
* On the gcc mailing list - expanding gcc to directly emit the CFT data
with a new command line option -gt.
CTF is a reduced form of debugging information whose main purpose is to
describe the type of C entities such as structures, unions, typedefs and
function arguments at the global scope only. It does not contain debug
information about source lines, location expressions, or local variables.
For more information on CTF, see the documentation in the libdtrace-ctf
source tree, available here:
<https://raw.githubusercontent.com/oracle/libdtrace-ctf/master/doc/ctf-format>.
This patch expands struct elfinfo by adding the .ctf section, which
contains CTF debugging info, and modifies elf_symfile_read() to read it.
If both DWARF and CTF exist in a program, only DWARF will be read. CTF data
will be read only when there is no DWARF. The two-stage symbolic reading
and setting strategy, partial and full, was used.
File ctfread.c contains functions to transform CTF data into gdb's internal
symbol table structures by iterately reading entries from CTF sections
of "data objects", "function info", "variable info", and "data types"
when setting up either partial or full symbol table. If the ELF symbol table
is available, e.g. not stripped, the CTF reader will associate the found
type information with these symbol entries. Due to the proximity between DWARF
and CTF (CTF being a much simplified subset of DWARF), some DWARF implementation
was reused to support CTF.
Test cases ctf-constvars.exp, ctf-cvexpr.exp, ctf-ptype.exp, and ctf-whatis.exp
have been added to verify the correctness of this support.
This patch has missing features and limitations which we will add and
address in the future patches.

This lets other programs read and write CTF-format data.
Two versioned shared libraries are created: libctf.so and
libctf-nobfd.so. They contain identical content except that
libctf-nobfd.so contains no references to libbfd and does not implement
ctf_open, ctf_fdopen, ctf_bfdopen or ctf_bfdopen_ctfsect, so it can be
used by programs that cannot use BFD, like readelf.
The soname major version is presently .0 until the linker API
stabilizes, when it will flip to .1 and hopefully never change again.
New in v3.
v4: libtoolize and turn into a pair of shared libraries. Drop
--enable-install-ctf: now controlled by --enable-shared and

This is quite complicated because the CTF section's contents depend on
the final contents of the symtab and strtab, because it has two sections
whose contents are shuffled to be in 1:1 correspondence with the symtab,
and an internal strtab that gets deduplicated against the ELF strtab
(with offsets adjusted to point into the ELF strtab instead). It is
also compressed if large enough, so its size depends on its contents!
So we cannot construct it as early as most sections: we cannot even
*begin* construction until after the symtab and strtab are finalized.
Thankfully there is already one section treated similarly: compressed
debugging sections: the only differences are that compressed debugging
sections have extra handling to deal with their changing name if
compressed (CTF sections are always called ".ctf" for now, though we
have reserved ".ctf.*" against future use), and that compressed
debugging sections have previously-uncompressed content which has to be
stashed away for later compression, while CTF sections have no content
at all until we generate it (very late).
BFD also cannot do the link itself: libctf knows how to do it, and BFD
cannot call libctf directly because libctf already depends on bfd for
file I/O. So we have to use a pair of callbacks, one, examine_strtab,
which allows a caller to examine the symtab and strtab after
finalization (called from elf_link_swap_symbols_out(), right before the
symtabs are written, and after the strtab has been finalized), and one
which actually does the emission (called emit_ctf simply because it is
grouped with a bunch of section-specific late-emission function calls at
the bottom of bfd_elf_final_link, and a section-specific name seems best
for that). emit_ctf is actually called *twice*: once from lang_process
if the emulation suggests that this bfd target does not examine the
symtab or strtab, and once via a bfd callback if it does. (This means
that non-ELF targets still get CTF emitted, even though the late CTF
emission stage is never called for them).
v2: merged with non-ELF support patch: slight commit message
adjustments.
v3: do not spend time merging CTF, or crash, if the CTF section is
explicitly discarded. Do not try to merge or compress CTF unless
linking.
v4: add CTF_COMPRESSION_THRESHOLD. Annul the freed input ctf_file_t's
after writeout: set SEC_IN_MEMORY on the output contents so a future
bfd enhancement knows it could free it. Add SEC_LINKER_CREATED |
SEC_KEEP to avoid having to add .ctf to the linker script. Drop
now-unnecessary ldlang.h-level elf-bfd.h include and hackery around
it. Adapt to elf32.em->elf.em and elf-generic.em->ldelf*.c
changes.
v5: fix tabdamage. Drop #inclusions in .h files: include in .c files,
.em files, and use struct forwards instead. Use bfd_section_is_ctf
inline function rather than SECTION_IS_CTF macro. Move a few
comments.

this stage.

callback right before the strtab is written out.

This patch moves the gdb/gnulib subdirectory to the top level.
It adjusts the top-level build system to build gnulib when necessary,
and changes gdb to use this. However, gdbserver still builds its own
copy of gnulib, just from the new source location.
A small hack was needed to ensure that gnulib is only built when gdb
is enabled. The Makefile only provides an ordering -- the directory
must be mentioned in configdirs to actually be compiled at all.
Most of the patch is just a "git mv" of gnulib, though a few minor
path adjustments were needed in some files there.
Tested by the buildbot.
