GCC fails to bootstrap when configured with --enable-languages=all on
machines that have older versions of GNAT installed as the system Ada
compiler. In configure, it's not sufficient to check whether gnat is
available, but whether a sufficiently recent version of GNAT is
installed. This patch tweaks config/acx.m4 so that conftest.adb also
contains a reference to System.CRTL.int64 as required by the current
version of gcc/ada/osint.adb. This fixes the build when the system
Ada is GNAT v4.8.5 (on Redhat 7) by disabling ada, but continues to
work fine when the system Ada is GNAT v11.3.1.

This patch enables DFP support on aarch64, by updating config/dfp.m4

It seems the license header was omitted when dfp.m4 was originally
contributed in 2010 (commit 3c39bca6bbb5, r0-102573 or svn r163815.
This copies the license from libdecnumber/configure.ac since dfp.m4
was originally extracted from that file.

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.
ChangeLog:
* Makefile.def: Add bootstrap to libbacktrace, libphobos, zlib, and
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.

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.

This is similar to what was done in

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.
ChangeLog:
* configure: Regenerate.
* configure.ac: Add --bootstrap-hwasan option.
config/ChangeLog:
* bootstrap-hwasan.mk: New file.
gcc/ChangeLog:
* doc/install.texi: Document new option.
