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 jump from v2.076.1 to v2.098.0 covers nearly 4 years worth of
development on the D programming language and run-time libraries.

libatomic.
* Makefile.in: Regenerate.
* Makefile.tpl (POSTSTAGE1_HOST_EXPORTS): Fix command for GDC.

So the problem here is that now the lto-plugin requires NM that works
with LTO to work so we need to pass down NM just like we do for ranlib
and ar.
OK? Bootstrapped and tested with --with-build-config=bootstrap-lto on aarch64-linux-gnu.
Note you need to use binutils 2.35 or later too due to ttps://sourceware.org/PR25355
(I will submit another patch to improve the installation instructions too).

This makes the host_shared value available to host makefile

There were two uses for the Darwin host config fragment:
The first is to arrange for targets that support mdynamic-no-pic
to be built with that enabled (since it makes a significant
difference to the compiler performance). We can be more specific
in the application of this, since it only applies to 32b hosts
plus powerpc64-darwin9.
The second was to work around a tool bug where -fno-PIE was not
propagated to the link stage. This second use is redundant,
since the buggy toolchain cannot bootstrap current GCC sources
anyway.
This makes the host fragment more specific and reduces the number
of toolchains for which it is included which reduces clutter in
configure lines.

With the introduction of C++20 modules and libcody, cc1plus and
cc1objplus gained a dependency on the socket functions. Before those
were merged into libc in Solaris 11.4, one needed to link with -lsocket -lnsl
on Solaris, so that merge broke the Solaris 11.3 build.
While we already have 4 different checks for those libraries in the
tree, I decided to import autoconf-archive's AX_LIB_SOCKET_NSL macro
instead. At the same time, the patch only links libcody and the
networking libs where needed (cc1plus, cc1objplus).
Bootstrapped without regressions on i386-pc-solaris2.11 (Solaris 11.3
and 11.4), sparc-sun-solaris2.11, and x86_64-pc-linux-gnu.

Handling stack variables has three features.
1) Ensure HWASAN required alignment for stack variables
When tagging shadow memory, we need to ensure that each tag granule is
only used by one variable at a time.
This is done by ensuring that each tagged variable is aligned to the tag
granule representation size and also ensure that the end of each
object is aligned to ensure the start of any other data stored on the
stack is in a different granule.
This patch ensures the above by forcing the stack pointer to be aligned
before and after allocating any stack objects. Since we are forcing
alignment we also use `align_local_variable` to ensure this new alignment
is advertised properly through SET_DECL_ALIGN.
2) Put tags into each stack variable pointer
Make sure that every pointer to a stack variable includes a tag of some
sort on it.
The way tagging works is:
1) For every new stack frame, a random tag is generated.
2) A base register is formed from the stack pointer value and this
random tag.
3) References to stack variables are now formed with RTL describing an
offset from this base in both tag and value.
The random tag generation is handled by a backend hook. This hook
decides whether to introduce a random tag or use the stack background
based on the parameter hwasan-random-frame-tag. Using the stack
background is necessary for testing and bootstrap. It is necessary
during bootstrap to avoid breaking the `configure` test program for
determining stack direction.
Using the stack background means that every stack frame has the initial
tag of zero and variables are tagged with incrementing tags from 1,
which also makes debugging a bit easier.
Backend hooks define the size of a tag, the layout of the HWASAN shadow
memory, and handle emitting the code that inserts and extracts tags from a
pointer.
3) For each stack variable, tag and untag the shadow stack on function
prologue and epilogue.
On entry to each function we tag the relevant shadow stack region for
each stack variable. This stack region is tagged to match the tag added to
each pointer to that variable.
This is the first patch where we use the HWASAN shadow space, so we need
to add in the libhwasan initialisation code that creates this shadow
memory region into the binary we produce. This instrumentation is done
in `compile_file`.
When exiting a function we need to ensure the shadow stack for this
function has no remaining tags. Without clearing the shadow stack area
for this stack frame, later function calls could get false positives
when those later function calls check untagged areas (such as parameters
passed on the stack) against a shadow stack area with left-over tag.
Hence we ensure that the entire stack frame is cleared on function exit.

This is an analogous option to --bootstrap-asan to configure. It allows
bootstrapping GCC using HWASAN.
For the same reasons as for ASAN we have to avoid using the HWASAN
sanitizer when compiling libiberty and the lto-plugin.
Also add a function to query whether -fsanitize=hwaddress has been
passed.

to cet.m4, use it in libiberty and lto-plugin to always enable Intel

On Linux/x86 host, enable Intel CET by default if assembler and compiler

The following patch provides some further math library fallbacks.
fmaf can be implemented using fma if available, fma and fmal can use
x * y + z as fallback, it is not perfect, but e.g. glibc on various arches
has been using that as fallback for many years,
and copysign/copysignl/fabs/fabsl can be implemented using corresponding
__builtin_* if we make sure that gcc expands it inline instead of using
a library call (these days it is expanded inline on most targets).

On bare-metal targets, I/O support is typically provided by a BSP and
requires a linker script and/or hosting library to be specified on the
linker command line. Linking an empty program with the default linker
script may succeed, however, which confuses libstdc++ configuration
when programs that probe for the presence of various I/O features fail
with link errors.

gcc: Add new configure options to allow static libraries to be selected
contains a couple of issues. First I failed to correctly regenerate
all of the configure files it should have done. Second, there was a
mistake in lib-link.m4, one of the conditions didn't use pure sh
syntax, I wrote this:
if x$lib_type = xauto || x$lib_type = xshared; then
When I should have written this:
if test "x$lib_type" = "xauto" || test "x$lib_type" = "xshared"; then
These issues were raised on the mailing list in these messages:

The motivation behind this change is to make it easier for a user to
link against static libraries on a target where dynamic libraries are
the default library type (for example GNU/Linux).
Further, my motivation is really for linking libraries into GDB,
however, the binutils-gdb/config/ directory is a copy of gcc/config/
so changes for GDB need to be approved by the GCC project first.
After making this change in the gcc/config/ directory I've run
autoreconf on all of the configure scripts in the GCC tree and a
couple have been updated, so I'll use one of these to describe what my
change does.
Consider libcpp, this library links against libiconv. Currently if
the user builds on a system with both static and dynamic libiconv
installed then autotools will pick up the dynamic libiconv by
default. This is almost certainly the right thing to do.
However, if the user wants to link against static libiconv then things
are a little harder, they could remove the dynamic libiconv from their
system, but this is probably a bad idea (other things might depend on
that library), or the user can build their own version of libiconv,
install it into a unique prefix, and then configure gcc using the
--with-libiconv-prefix=DIR flag. This works fine, but is somewhat
annoying, the static library available, I just can't get autotools to
use it.
My change then adds a new flag --with-libiconv-type=TYPE, where type
is either auto, static, or shared. The default auto, ensures we keep
the existing behaviour unchanged.
If the user configures with --with-libiconv-type=static then the
configure script will ignore any dynamic libiconv it finds, and will
only look for a static libiconv, if no static libiconv is found then
the configure will continue as though there is no libiconv at all
available.
Similarly a user can specify --with-libiconv-type=shared and force the
use of shared libiconv, any static libiconv will be ignored.
As I've implemented this change within the AC_LIB_LINKFLAGS_BODY macro
then only libraries configured using the AC_LIB_LINKFLAGS or
AC_LIB_HAVE_LINKFLAGS macros will gain the new configure flag.
If this is accepted into GCC then there will be follow on patches for
binutils and GDB to regenerate some configure scripts in those
projects.
For GCC only two configure scripts needed updated after this commit,
libcpp and libstdc++-v3, both of which link against libiconv.
config/ChangeLog:
* lib-link.m4 (AC_LIB_LINKFLAGS_BODY): Add new
--with-libXXX-type=... option. Use this to guide the selection of
either a shared library or a static library.

* configure: Regenerate.

Provide means, in the form of a `--with-toolexeclibdir=' configuration
option, to override the default installation directory for target
libraries, otherwise known as $toolexeclibdir. This is so that it is
possible to get newly-built libraries, particularly the shared ones,
installed in a common place, so that they can be readily used by the
target system as their host libraries, possibly over NFS, without a need
to manually copy them over from the currently hardcoded location they
would otherwise be installed in.
In the presence of the `--enable-version-specific-runtime-libs' option
and for configurations building native GCC the option is ignored.

configure scripts
The new arm-uclinuxfdpiceabi target behaves pretty much like
arm-linux-gnueabi. In order to enable the same set of features, we
have to update several configure scripts that generally match targets
like *-*-linux*: in most places, we add *-uclinux* where there is
already *-linux*, or uclinux* when there is already linux*.
In gcc/config.gcc and libgcc/config.host we use *-*-uclinuxfdpiceabi
because there is already a different behaviour for *-*uclinux* target.
In libtool.m4, we use uclinuxfdpiceabi in cases where ELF shared
libraries support is required, as uclinux does not guarantee that.

Without this change, libstdc++ is built without futex symbols if GCC
rejects implicit function declarations by default.

Although BOOT_CFLAGS can be used to bootstrap with -Og, having a
dedicated build config is sometimes more convenient.
