Prevent internal aligned_alloc clashing with libc version

If configure fails to detect aligned_alloc we will try to define our

<stdlib.h>. Use a namespace to keep them distinct.

Cuda driver api functions cuLinkAddData and cuLinkCreate are available starting
version 5.5.  In version 6.5, they are remapped onto _v2 versions.

The dlopen interface of the libgomp nvptx plugin uses the _v2 versions, so it
won't work with a cuda driver with driver api version lower than 6.5.

This patch fixes the problem by testing for the presence of the _v2 versions,
and falling back to the original versions in case of absence of the _v2
versions.

6 years ago[AArch64] Fix -mlow-precision-div (PR 86838)
Richard Sandiford [Tue, 7 Aug 2018 17:22:19 +0000 (17:22 +0000)]
[AArch64] Fix -mlow-precision-div (PR 86838)

The "@" handling broke -mlow-precision-div, because the scalar forms of
the instruction were provided by a pattern that also provided FRECPX
(and so were parameterised on an unspec code as well as a mode),
while the SIMD versions had a dedicated FRECPE pattern.  This patch
moves the scalar FRECPE handling to the SIMD pattern too (as for FRECPS)
and uses a separate pattern for FRECPX.

The convention in aarch64-simd-builtins.def seemed to be to add
comments only if the mapping wasn't obvious (i.e. not just sticking
"aarch64_" on the beginning and "<mode>" on the end), so the patch
deletes the reference to the combined pattern instead of rewording it.

There didn't seem to be any coverage of -mlow-precision-div in the
testsuite, so the patch adds some tests for it.

[libgomp, nvptx] Handle CUDA_ONE_CALL_MAYBE_NULL

This patch adds handling of functions that may not be present in the cuda
driver.

Such a function can be declared using CUDA_ONE_CALL_MAYBE_NULL in cuda-lib.def,
it can be called with the usual convenience macros, but before calling its
presence needs to be tested using new macro CUDA_CALL_EXISTS.

When using the dlopen interface (PLUGIN_NVPTX_DYNAMIC == 1), we allow
non-present functions by allowing dlsym to return NULL.  Otherwise
(PLUGIN_NVPTX_DYNAMIC == 0) we declare the non-present function to be weak.

Build and reg-tested libgomp on x86_64 with nvidia accelerator, with and without
--disable-cuda-driver, in combination with a trigger patch that adds a
non-existing function foo to cuda-lib.def:
...
CUDA_ONE_CALL_MAYBE_NULL (foo)
...
and declares it in plugin-nvptx.c:
...
CUresult foo (void);
...
and then uses it in nvptx_init after the init_cuda_lib call:
...
  if (CUDA_CALL_EXISTS (foo))
    CUDA_CALL (foo);
...

Also build and reg-tested on x86_64 with nvidia accelerator, with and without
--disable-cuda-driver, in combination with a trigger patch that replaces all
CUDA_ONE_CALLs in cuda-lib.def with CUDA_ONE_CALL_MAYBE_NULL, and guards two
CUDA_CALLs with CUDA_CALL_EXISTS, one for a regular fn, and one for a fn that is
a define in cuda/cuda.h.

Richard Sandiford [Fri, 3 Aug 2018 12:56:55 +0000 (12:56 +0000)]
Handle SLP of call pattern statements

We couldn't vectorise:

  for (int j = 0; j < n; ++j)
    {
      for (int i = 0; i < 16; ++i)
a[i] = (b[i] + c[i]) >> 1;
      a += step;
      b += step;
      c += step;
    }

at -O3 because cunrolli unrolled the inner loop and SLP couldn't handle
AVG_FLOOR patterns (see also PR86504).  The problem was some overly
strict checking of pattern statements compared to normal statements
in vect_get_and_check_slp_defs:

          switch (gimple_code (def_stmt))
            {
            case GIMPLE_PHI:
            case GIMPLE_ASSIGN:
      break;

    default:
      if (dump_enabled_p ())
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
 "unsupported defining stmt:\n");
      return -1;
            }

The easy fix would have been to add GIMPLE_CALL to the switch,
but I don't think the switch is doing anything useful.  We only create
pattern statements that the rest of the vectoriser can handle, and the
other checks in this function and elsewhere check whether SLP is possible.

I'm also not sure why:

          if (!first && !oprnd_info->first_pattern
      /* Allow different pattern state for the defs of the
 first stmt in reduction chains.  */
      && (oprnd_info->first_dt != vect_reduction_def

is necessary.  All that should matter is that the statements in the
node are "similar enough".  It turned out to be quite hard to find a
convincing example that used a mixture of pattern and non-pattern
statements, so bb-slp-pow-1.c is the best I could come up with.
But it does show that the combination of "xi * xi" statements and
"pow (xj, 2) -> xj * xj" patterns are handled correctly.

The patch therefore just removes the whole if block.

The loop also needed commutative swapping to be extended to at least
AVG_FLOOR.

This gives +3.9% on 525.x264_r at -O3.

Tom de Vries [Thu, 2 Aug 2018 15:59:01 +0000 (15:59 +0000)]
[nvptx] Ignore c++ exceptions

The nvptx port can't support exceptions using sjlj, because ptx does not
support sjlj.  However, default_except_unwind_info still returns UI_SJLJ, even
even if we configure with --disable-sjlj-exceptions, because UI_SJLJ is the
fallback option.

The reason default_except_unwind_info doesn't return UI_DWARF2 is because
DWARF2_UNWIND_INFO is not defined in defaults.h, because
INCOMING_RETURN_ADDR_RTX is not defined, because there's no ptx equivalent.

Testcase libgomp.c++/for-15.C currently doesn't compile unless fno-exceptions
is added because:
- it tries to generate sjlj exception handling code, and
- it tries to generate exception tables using label-addressed .byte sequence.
  Ptx doesn't support generating random data at a label, nor being able to
  load/write data relative to a label.

This patch fixes the first problem by using UI_TARGET for nvptx.

The second problem is worked around by generating all .byte sequences commented
out.  It would be better to have a narrower workaround, and define
TARGET_ASM_BYTE_OP to "error: .byte unsupported " or some such.

This patch does not enable exceptions for nvptx, it merely allows c++ programs
to run correctly if they do no use exception handling.

Build and reg-tested on x86_64 with nvptx accelerator.
