D attribute support has been updated to have a baseline parity with the
LLVM D compiler's own `ldc.attributes'.
The handler that extracts GCC attributes from a list of UDAs has been
improved to take care of some mistakes that could have been warnings.
UDAs attached to field variables are also now processed for any GCC
attributes attached to them.
The following new attributes have been added to the D front-end:
- @attribute("alloc_size")
- @attribute("used")
- @attribute("optimize")
- @attribute("restrict")
- @attribute("cold")
- @attribute("noplt")
- @attribute("target_clones")
- @attribute("no_icf")
- @attribute("noipa")
- @attribute("symver")
With convenience aliases in a new `gcc.attributes' module to match
the same naming convention as `ldc.attributes':
- @allocSize()
- @assumeUsed
- @fastmath
- @naked
- @restrict
- @cold
- @noplt
- @optStrategy()
- @polly
- @section()
- @target()
- @weak
The old gcc.attribute module has been deprecated, along with the removal
of the following attribute handlers:
- @attribute("alias"): Has been superseded by `pragma(mangle)'.
- @attribute("forceinline"): Renamed to always_inline.

D front-end changes:
- Explicit package visibility attribute is now always applied to
introducing scopes.
- Added `__traits(totype, string)' to convert mangled type string to an
existing type.
- Printf-like and scanf-like functions are now detected by prefixing
them with `pragma(printf)' for printf-like functions or
`pragma(scanf)' for scanf-like functions.
- Added `__c_wchar_t', `__c_complex_float', `__c_complex_double', and
`__c_complex_real' types for interfacing with C and C++.
- Template alias parameters can now be instantiated with basic types,
such as `int` or `void function()`.
- Mixins can now be used as types in the form `mixin(string) var'.
- Mixin expressions can take an argument list, same as `pragma(msg)'.
- Implement DIP1034, add `typeof(*null)' types to represent `noreturn'.
- `pragma(msg)' can print expressions of type `void'.
- It is now an error to use private variables selectively imported from
other modules. Due to a bug, some imported private members were
visible from other modules, violating the specification.
- Added new syntax to declare an alias to a function type using the
`alias' syntax based on the assignment operator.
- Function literals can now return a value by reference.
Phobos changes:
- Synchronize C bindings with the latest port fixes in upstream druntime.
- Added alias for a `noreturn' type in object.d
- Make use of the new `pragma(printf)' and `pragma(scanf)' pragmas, fix
all code that got flagged as being incorrect.
- Fixed code that relied on bugs in the D import package system.

The libgdruntime_convenience library was built with `-fversion=Shared',
but the libphobos part wasn't when creating the static library.
As there are no issues compiling in Shared code into the static library,
to avoid mismatches the flag is now always present when --enable-shared
is turned on. Libtool's compiler PIC D flag is now the combination of
compiler PIC and D Shared flags, and AM_DFLAGS passes `-prefer-pic' to
libtool unless --enable-shared is turned off.

When libphobos is configured with --enable-cet, this adds extra fields
to the Fiber class to support the ucontext_t fallback implementation.
These fields get omitted when compiling user code unless they also used
`-fversion=CET' to build their project, which resulted in data being
overwritten from within swapcontext().
On reviewing the ucontext_t definitions, it was found that the shadow
stack fields were missing, and the struct size didn't match up on X32.
This has been fixed in upstream druntime and merged down here.

As a prerequesite for PR94304, it becomes easier to manage selectively
compiling sublibraries when there's only one library to link to.
So a druntime convenience library is built to be part of phobos, however
separate druntime library is still built and installed, to allow linking
only to the core runtime explicitly, rather than pulling in the entire
standard library with it.
The gdc driver no longer generates an '-lgdruntime' option, and the
inclusion of the libdruntime library path has been removed from the
testsuite.

* d-spec.cc (LIBDRUNTIME): Remove.
(LIBDRUNTIME_PROFILE): Remove.
(lang_specific_driver): Don't link in libgdruntime.

* testsuite/testsuite_flags.in: Likewise.
This is yet another old option that would have been somewhat useful back
before the D front-end implementation was able to support compiling
without the Druntime library.
Now however, -fno-druntime makes the gcstub package redundant, so the
option has been removed, along with the package itself.
libphobos/ChangeLog:
* configure: Regenerate.
* libdruntime/Makefile.am (ALL_DRUNTIME_INSTALL_DSOURCES): Remove
DRUNTIME_DSOURCES_GC and DRUNTIME_DSOURCES_GCSTUB.

As GDCFLAGS is overriden by the top-level make file with '-O2 -g',
libphobos ends up always being built with all contracts, invariants, and
asserts compiled in. This adds a new configurable that defaults to omit
compiling any run-time checks into the library using '-frelease'.
Other choices either set the flags '-fno-release', enabling all run-time
checks, or '-fassert', which only compiles in asserts.
The omission of compiling in contracts results in a smaller library
size, with faster build times.

This option is not useful on its own as all posix modules require the
compiler to predefine version(Posix) anyway. So the option has been
removed, and logic moved into DRUNTIME_OS_SOURCES, where the conditional
DRUNTIME_OS_POSIX is set instead.

* configure: Regenerate.
* configure.ac: Remove DRUNTIME_OS_UNIX.

DRUNTIME_OS_POSIX is true.

* m4/druntime/os.m4 (DRUNTIME_OS_UNIX): Remove, move AM_CONDITIONAL
logic to...
(DRUNTIME_OS_SOURCES): ...here. Rename conditional to
DRUNTIME_OS_POSIX.
This moves WARN_DFLAGS from GDCFLAGS to AM_DFLAGS so it is always
included in the build and testsuite of libphobos. Currently, this
doesn't happen as GDCFLAGS is overriden by it being set at the
top-level.
libphobos/ChangeLog:
* Makefile.in: Regenerate.
* configure: Regenerate.
* configure.ac: Substite WARN_DFLAGS independently of GDCFLAGS.
* libdruntime/Makefile.am: Add WARN_DFLAGS to AM_DFLAGS.
* libdruntime/Makefile.in: Regenerate.
* src/Makefile.am: Add WARN_DFLAGS to AM_DFLAGS.

Improves the versioning of IeeeFlags and FloatingPointControl code and
unit-tests, making it clearer which targets can and cannot support it.

With this patch we get rid of the usage of the glibc-internal symbol
__tls_get_addr_internal.
If build with multilib, the file
gcc/libphobos/libdruntime/config/systemz/get_tls_offset.S is used
for both configurations: systemz and s390.
Therefore both implementations are now in the systemz file which
uses an "#ifdef __s390x__" in order to distinguish both cases.
The s390 file is just including the systemz one.

* m4/druntime/cpu.m4: Add s390x and s390.
The ordering of some fields in struct sigaction on s390x (64bit)
differs compared to s390 and other architectures.
This patch adjusts this order according to the definition of
<glibc-src>/sysdeps/unix/sysv/linux/s390/bits/sigaction.h
Without this fix e.g. the call
sigaction( suspendSignalNumber, &sigusr1, null ) in thread.d
leads to setting the sa_restorer field to 0xffffffffffffffff.
In case a signal, the signal handler returns to this address
and the process stops with a SIGILL.
This was observable in several execution testcases on s390x:

libphobos.druntime_shared/core/thread.d
libphobos.thread/tlsgc_sections.d
libphobos.allocations/tls_gc_integration.d
