[nvptx] Handle V2DI/V2SI mode in nvptx_gen_shuffle

With the pr96628-part1.f90 source and -ftree-slp-vectorize, we run into an
ICE due to the fact that V2DI mode is not handled in nvptx_gen_shuffle.

Fix this by adding handling of V2DI as well as V2SI mode in
nvptx_gen_shuffle.

Build and reg-tested on x86_64 with nvptx accelerator.

veclower: Don't ICE on .VEC_CONVERT calls with no lhs [PR96426]

.VEC_CONVERT is a const internal call, so normally if the lhs is not used,
we'd DCE it far before getting to veclower, but with -O0 (or perhaps
-fno-tree-dce and some other -fno-* options) it can happen.
But as the internal fn needs the lhs to know the type to which the
conversion is done (and I think that is a reasonable representation, having
some magic another argument and having to create constants with that type
looks overkill to me), we just should DCE those calls ourselves.
During veclower, we can't really remove insns, as the callers would be
upset, so this just replaces it with a GIMPLE_NOP.

Martin Jambor [Mon, 3 Aug 2020 16:13:00 +0000 (18:13 +0200)]
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.

var-tracking: fix uninitialised use of 'in_pending' [PR96404]

r11-2447-g:1212cfad093 ("Improve var-tracking dataflow

from:

    in_pending = sbitmap_alloc (last_basic_block_for_fn (cfun));
    bitmap_ones (in_pending);

to more complex partial bit population algorithm. Due to presence
of uninitialized bits gcc started injecting extra debug entries
in seemigly arbitrary locations and started failing stage2/stage3
bootstrap comparison.

valgrind detected unilitialized bits as:

  Conditional jump or move depends on uninitialised value(s)
     at 0xDBED3B: vt_find_locations() (var-tracking.c:7230)
     by 0xDBF2FB: variable_tracking_main_1() (var-tracking.c:10519)

     by 0x14911F9: sbitmap_alloc(unsigned int) (sbitmap.c:51)

4 years agoc: Fix bogus vector initialisation error [PR96377]
Richard Sandiford [Sat, 1 Aug 2020 11:41:28 +0000 (12:41 +0100)]
c: Fix bogus vector initialisation error [PR96377]

One of the problems in this PR was that if we had:

  vector_type1 array[] = { vector_value1 };

process_init_element would only treat vector_value1 as initialising
a vector_type1 if they had the same TYPE_MAIN_VARIANT.  This has
several problems:

(1) It gives confusing error messages if the vector types are
    incompatible.  (Tested by gcc.dg/pr96377-1.c.)

(2) It means that we reject code that should be valid with
    -flax-vector-conversions.  (Tested by gcc.dg/pr96377-2.c.)

(3) On arm and aarch64 targets, it means that we reject some
    initializers that mix Advanced SIMD and standard GNU vectors.
    These vectors have traditionally had different TYPE_MAIN_VARIANTs
    because they have different mangling schemes.  (Tested by
    gcc.dg/pr96377-[3-6].c.)

(4) It means that we reject SVE initializers that should be valid.
    (Tested by gcc.target/aarch64/sve/gnu_vectors_[34].c.)

(5) After r11-1741-g:31427b974ed7b7dd54e2 we reject:

      arm_neon_type1 array[] = { k ^ arm_neon_value1 };

    because applying the binary operator to arm_neon_value1 strips
    the "Advanced SIMD type" attributes that were added in that patch.
    Stripping the attributes is problematic for other reasons though,
    so that still needs to be fixed separately.

4 years agoc++: Use error_at rather than warning_at for missing return in constexpr functions...
Jakub Jelinek [Fri, 31 Jul 2020 21:08:00 +0000 (23:08 +0200)]
c++: Use error_at rather than warning_at for missing return in constexpr functions [PR96182]

For C++11 we already emit an error if a constexpr function doesn't contain
a return statement, because in C++11 that is the only thing it needs to
contain, but for C++14 we would normally issue a -Wreturn-type warning.

As mentioned by Jonathan, such constexpr functions are invalid, no
diagnostics required, because there doesn't exist any arguments for
which it would result in valid constant expression.

This raises it to an error in such cases.  The !LAMBDA_TYPE_P case
is to avoid error on g++.dg/pr81194.C where the user didn't write
constexpr anywhere and the operator() is compiler generated.

2020-07-31  Jakub Jelinek  <jakub@redhat.com>

PR c++/96182
* decl.c (finish_function): In constexpr functions use for C++14 and
later error instead of warning if no return statement is present and
diagnose it regardless of warn_return_type.  Move the warn_return_type
diagnostics earlier in the function.
