This is the library fix for PR103520 that also prevents the garbage
collector from releasing live memory.  However this requires that the
host compiler has been patched with this fix, so the GC will remain
disabled in the D front-end for now until enough time has passed for
this to have trickled down into enough releases.

libphobos/ChangeLog:

	* libdruntime/core/thread/osthread.d (callWithStackShell): Push all
	callee-save registers on the stack for AArch64 and ARM.

Fixes a typo that occurred during the splitting of the std.math module
into a package.

libphobos/ChangeLog:

	* src/std/math/hardware.d (FloatingPointControl.getControlState): Add
	missing ControlState variable for AArch64.

In the gdc driver, this takes the previous fix for the Darwin D
bootstrap, and extends it to the -static-libphobos option as well.
Rather than pushing the -static-libphobos option back onto the command
line, the setting of SKIPOPT is instead conditionally removed.  The same
change has been repeated for -static-libstdc++ so there is now no need
to call generate_option to re-add it.

In the gcc driver, -static-libphobos has been added as a common option,
validated, and a new outfile substition added to config/darwin.h to
correctly replace -lgphobos with libgphobos.a.

gcc/ChangeLog:

	* common.opt (static-libphobos): Add option.
	* config/darwin.h (LINK_SPEC): Substitute -lgphobos with libgphobos.a
	when linking statically.
	* gcc.c (driver_handle_option): Set -static-libphobos as always valid.

gcc/d/ChangeLog:

	* d-spec.cc (lang_specific_driver): Set SKIPOPT on -static-libstdc++
	and -static-libphobos only when target supports LD_STATIC_DYNAMIC.
	Remove generate_option to re-add -static-libstdc++.

libphobos/ChangeLog:

	* testsuite/testsuite_flags.in: Add libphobos library directory as
	search path to --gdcldflags.

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.

Depending on the permutation of CPU, OS version and shared/non-
shared library inclusion, we get can get two warnings from the
external tools (ld64, dsymutil) which are not actually GCC issues
but relate to the external tools.  These are alrrady pruned in
the main testsuite, this adds them to the library.

libphobos/ChangeLog:

	* testsuite/lib/libphobos.exp: Prune warnings from external
	tool bugs.

As of macOS 11, libunwind now requires more stack space than 16k, so
default to a larger stack size. This is only applied to X86 as the
PAGESIZE is still 4k, however on AArch64 it is 16k.

libphobos/ChangeLog:

	* libdruntime/core/thread/fiber.d (defaultStackPages): Increase size
	on OSX X86_64 targets.

Fixes a EXC_BAD_ACCESS issue seen on Darwin when the libphobos DSO gets
unloaded.  Based on reading libgcc's emutls implementation, as it
doesn't call __gthread_key_delete directly, neither should libphobos.

libphobos/ChangeLog:

	* libdruntime/gcc/emutls.d (emutlsDestroyThread): Don't remove entry
	from global array.
	(_d_emutls_destroy): Don't call __gthread_key_delete.

The _Unwind_Exception struct had its alignment adjusted to 16-bytes,
however malloc() on Solaris X86 is not guaranteed to allocate memory
aligned to 16-bytes as well.

	PR d/102837

libphobos/ChangeLog:

	* libdruntime/gcc/deh.d (ExceptionHeader.free): Use memset to reset
	contents of internal EH storage.

This is analogous to __gdc_personality, which ignores in-flight
exceptions that we haven't collided with yet.

libphobos/ChangeLog:

	* libdruntime/gcc/deh.d (ExceptionHeader.getClassInfo): Move to...
	(getClassInfo): ...here as free function.  Add lsda parameter.
	(scanLSDA): Pass lsda to actionTableLookup.
	(actionTableLookup): Add lsda parameter, pass to getClassInfo.
	(__gdc_personality): Remove currentCfa variable.

By default, D run-time has a top level exception handler to catch
anything that was uncaught by user code.  However when the
`rt_trapExceptions' flag is cleared, this handler would not be enabled,
and this termination would occur, aborting the program, but without any
information about the exception.

libphobos/ChangeLog:

	* libdruntime/gcc/deh.d (_d_print_throwable): Declare.
	(_d_throw): Print stacktrace before terminating program due to
	uncaught exception.

The core.runtime module always overrides the default parameter value for
constructor calls.  MaxAlignment is not required because a class can be
created on the stack with the `scope' keyword.

libphobos/ChangeLog:

	* libdruntime/core/runtime.d (runModuleUnitTests): Use scope to new
	LibBacktrace on the stack.
	* libdruntime/gcc/backtrace.d (FIRSTFRAME): Remove.
	(LibBacktrace.MaxAlignment): Remove.
	(LibBacktrace.this): Remove default initialization of firstFrame.
	(UnwindBacktrace.this): Likewise.

For interoperability with C++ EH, the alignment should match, otherwise
D may not be able to intercept exceptions thrown from C++.

libphobos/ChangeLog:

	* libdruntime/gcc/unwind/generic.d (__aligned__): Define.
	(_Unwind_Exception): Align struct to __aligned__.

The default supplied main function as read when compiling with `-fmain'
has extern(D) linkage.  However this does not work when mixing this
option together with `-fno-druntime'.

	PR d/102476

gcc/testsuite/ChangeLog:

	* gdc.dg/pr102476.d: New test.

libphobos/ChangeLog:

	* libdruntime/__main.di: Define main function as extern(C) when
	compiling without D runtime.

libphobos/ChangeLog:

	* m4/druntime/os.m4: Update comment for DRUNTIME_OS_SOURCES.

The D run-time library does not depend on zlib, so only include it in
the library when Phobos is being built as well.

libphobos/ChangeLog:

	* src/Makefile.am: Don't add zlib when ENABLE_LIBDRUNTIME_ONLY.
	* src/Makefile.in: Regenerate.

libphobos/ChangeLog:

	* configure: Regenerate.
	* m4/autoconf.m4 (AC_LANG_PROGRAM): Declare module name 'object'.
	* m4/gcc_support.m4 (WITH_LOCAL_DRUNTIME): Compile tests with
	-fno-druntime.

Improves semantic passes in the front-end around the `foreach' and
`static foreach' statements to be more resilient to compiling in a
minimal D runtime environment.  Checking of the index type has been
improved as well so now there won't be needless compiler errors when
using 8 or 16-bit integers as index types when the size fits the
expected loop range.

	* src/std/process.d (unittest): Remove tmpname on exit.
	* src/MERGE: Merge upstream phobos 63f4caa90.

The function declarations were updated to use `const scope', but the
static asserts were not.
