44d9d55c6d include: Allow for our md5.h to defer to the system header
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.

b032103265 obstack.h __PTR_ALIGN vs. ubsan
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.

3bc75533d1 openmp: Add support for strict modifier on grainsize/num_tasks clauses
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++.

34dbb5f346 include: Fix -Wundef warnings in ansidecl.h
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++.

18d0fad77b BTF: Support for BTF_KIND_FLOAT
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.

77380c6806 libiberty: add htab_eq_string
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.

	* hashtab.c (htab_eq_string): New function.

a3bf6ce7f2 c++: Adjust mangling of __alignof__ [PR88115]
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).

de8421dd8a Add codes for DWARF v5 .dwp sections to dwarf2.h.
(Note: This patch has already been accepted/committed in binutils/GDB.
This will bring the same change into the GCC tree.)

For DWARF v5 Dwarf Package Files (.dwp files), the section identifier encodings
have changed. This patch updates dwarf2.h to contain the new
encodings.  The table below shows the old & new encodings:
[ref http://dwarfstd.org/doc/DWARF5.pdf, section 7.3.5. ]

c56684fd61 Removal of HSA offloading from gcc and libgomp
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.

bsearch_r is required, not optional, at this point because as far as I
