Now that GCC is compiled as C++11 there is no need to keep the C++03
implementation of gnu::unique_ptr.
This removes the unique-ptr.h header and replaces it with <memory> in
system.h, and changes the INCLUDE_UNIQUE_PTR macro to INCLUDE_MEMORY.
Uses of gnu::unique_ptr and gnu::move can be replaced with
std::unique_ptr and std::move. There are no uses of unique_xmalloc_ptr
or xmalloc_deleter in GCC.

* engine.cc: Define INCLUDE_MEMORY instead of INCLUDE_UNIQUE_PTR.

Up to now the libgomp GCN plugin has been finding the offload variables
by using a symbol lookup, but the AMD runtime requires that the symbols are
global for that to work. This was ensured by mkoffload as a post-procssing
step, but the LLVM 13 assembler no longer accepts this in the case where the
variable was previously declared differently.
This patch switches to locating the symbols directly from the
offload_var_table, which means that only one symbol needs to be forced
global.
This changes breaks the libgomp image compatibility so GOMP_VERSION_GCN has
also been bumped.
gcc/ChangeLog:
* config/gcn/mkoffload.c (process_asm): Process the variable table
completely differently.
(process_obj): Encode the varaible data differently.
include/ChangeLog:
* gomp-constants.h (GOMP_VERSION_GCN): Bump.
libgomp/ChangeLog:
* plugin/plugin-gcn.c (struct gcn_image_desc): Remove global_variables.
(GOMP_OFFLOAD_load_image): Locate the offload variables via the

This patch implements several C++ specific mapping capabilities introduced for
OpenMP 5.0, including implicit mapping of this[:1] for non-static member
functions, zero-length array section mapping of pointer-typed members,
lambda captured variable access in target regions, and use of lambda objects
inside target regions.
Several adjustments to the C/C++ front-ends to allow more member-access syntax
as valid is also included.

This patch implements relaxing the requirements when a map with the implicit
attribute encounters an overlapping existing map. As the OpenMP 5.0 spec
describes on page 320, lines 18-27 (and 5.1 spec, page 352, lines 13-22):
"If a single contiguous part of the original storage of a list item with an
implicit data-mapping attribute has corresponding storage in the device data
environment prior to a task encountering the construct that is associated with
the map clause, only that part of the original storage will have corresponding
storage in the device data environment as a result of the map clause."

This came up in the context of libsanitizer, where platform-specific
support for FreeBSD relies on aspects provided by FreeBSD's own md5.h.
Address this by allowing GCC's md5.h to pull in the system header
instead, controlled by a new macro USE_SYSTEM_MD5.

Current ubsan complains on every use of __PTR_ALIGN (when ptrdiff_t is
as large as a pointer), due to making calculations relative to a NULL
pointer. This patch avoids the problem by extracting out and
simplifying __BPTR_ALIGN for the usual case. I've continued to use
ptrdiff_t here, where it might be better to throw away __BPTR_ALIGN
entirely and just assume uintptr_t exists.
* obstack.h (__PTR_ALIGN): Expand and simplify __BPTR_ALIGN
rather than calculating relative to a NULL pointer.

With strict: modifier on these clauses, the standard is explicit about
how many iterations (and which) each generated task of taskloop directive
should contain. For num_tasks it actually matches what we were already
implementing, but for grainsize it does not (and even violates the old
rule - without strict it requires that the number of iterations (unspecified
which exactly) handled by each generated task is >= grainsize argument and
< 2 * grainsize argument, with strict: it requires that each generated
task handles exactly == grainsize argument iterations, except for the
generated task handling the last iteration which can handles <= grainsize
iterations).
The following patch implements it for C and C++.

This quashes -Wundef warnings in ansidecl.h when compiled in C or C++.
In C, __cpp_constexpr and __cplusplus aren't defined so we evaluate
them to 0; conversely, __STDC_VERSION__ is not defined in C++.
This has caused grief when -Wundef is used with -Werror.
I've also tested -traditional-cpp.
include/ChangeLog:
* ansidecl.h: Check if __cplusplus is defined before checking
the value of __cpp_constexpr and __cplusplus. Don't check
__STDC_VERSION__ in C++.

Add BTF_KIND_FLOAT, a new BTF type kind which has recently stabilized in
the linux kernel [1]. This kind is used for encoding floating point
types, and is of particular use when generating BTF for some s390
arch-specific kernel headers.
Also update some BTF tests which previously used floating point types to
check correct behavior for types with no BTF representation.

The libiberty hash table includes a helper function for strings, but
no equality function. Consequently, this equality function has been
reimplemented a number of times in both the gcc and binutils-gdb
source trees. This patch adds the function to the libiberty hash
table, as a step toward the goal of removing all the copies.
One change to gcc is included here. Normally I would have put this in
the next patch, but gensupport.c used the most natural name for its
reimplementation of this function, and this can't coexist with the
extern function in libiberty.

r11-4926 made __alignof__ get mangled differently from alignof,
encoding __alignof__ as a vendor extended operator. But this
mangling is problematic for the reasons mentioned in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88115#c6.
This patch changes our mangling of __alignof__ to instead use the
new "vendor extended expression" syntax that's proposed in
https://github.com/itanium-cxx-abi/cxx-abi/issues/112. Clang does
the same thing already, so after this patch Clang and GCC agree
about the mangling of __alignof__(type) and __alignof__(expr).

This patch removes the generation of HSAIL from the compiler, the HSA
offloading plugin from libgomp and the associated testsuite tests and
infrastructure bits from the respective testsuites.
Apart from removal of the obvious files, I removed bits that I found
by searching for HSA related terms and by re-tracing my steps and
looking at the patches that introduced HSA in the first place. I did
not remove everything these patches brought in, for example:
- the mechanism to pass offload-target specific info from the application to
the offloading plugin - but the same mechanism is also used to
communicate number of teams and the thread limit to all offload targets.
- run_func hook in gomp_device_descr stays too, although now it is
not used. If some future offload target would like the ability to
refuse to offload some functions, it can use it. It is easy to
remove as a follow-up if it is considered clutter, though.
- configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH
and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too.
- Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant
from gomp-constants.h) appears in the source of the amdgcn libgomp
plugin, although I tend to think that code path is not ever used
and this patch certainly removes it from the compiler.
Nevertheless, it seems it has potential value beyond HSAIL and so
I've kept it, it can of course always be easily removed in the
future of GCN folk abandon it too.
- I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA
need to stay indefinitely too just so that no future offload
target picks that number.
- I have kept dg-require-effective-target
offload_device_nonshared_as requirement of thests which have it.
It is quite probable I missed some small HSA artifacts but those
should be easy to remove later as we find them.
