[arm] PR target/89400 fix thumb1 unaligned access expansion

Armv6 has support for unaligned accesses to memory.  However, the
thumb1 code patterns were trying to use the 32-bit code constraints.
One failure mode from this was that the patterns are designed to be
compatible with conditional execution and this was then causing an
assert in the compiler.

The unaligned_loadhis pattern is only used for expanding extv, which
in turn is only enabled for systems supporting thumb2.  Given that
there is no simple expansion for a thumb1 sign-extending load (the
instruction has no immediate offset form and requires two registers in
the address) it seems simpler to just disable this for thumb1.

Fixed thusly:

PR target/89400
* config/arm/arm.md (unaligned_loadsi): Add variant for thumb1.
Restrict 'all' variant to 32-bit configurations.

change the internal numbers, and sometimes we do that without
remembering this gotcha anyway; so let's make everything independent
of the internal numbers.

For those registers that are not recognised here (we still have MQ for
example, but also the GCC-internal frame pointer and arg pointer
registers), this just returns the internal register number.  This is a
bit worrying: that number could be the same as that for a register we
validly want to have in debug info.  I first had a gcc_unreachable ()
for that, but this does now work because dwarf2cfi calls
rs6000_dbx_register_number for every internal register.  Then I just
returned 0 for the internal regs, but that causes various regression
tests to fail.  So now I return the internal register number again,
as it was before; but this needs to be fixed.

within inline assembly, to access IEEE exception flags.  The use of
these instructions is not allowed when building for a soft-float ABI.

Correct the problem by wrapping said inline assembly into a conditional
such that if `D_SoftFloat' is true, then reads from IEEE exception flags
return 0 and writes are ignored instead, complementing r270522
("libphobos: Add D support for RISC-V Linux"), which is an updated
version of <https://gcc.gnu.org/ml/gcc-patches/2019-04/msg00325.html>,

Adjust Doxygen processing of pb_ds containers

Several of the pb_ds headers are intended to be included multiple times,
within the definition of various class templates. The including files
define macros like PB_DS_CLASS_C_DEC and PB_DS_GEN_POS before including
these headers.

In some cases the types defined in the headers are actually nested types
within other classes, and so should not have been documented as though
they are declared in the global namespace, as in:
https://gcc.gnu.org/onlinedocs/gcc-8.3.0/libstdc++/api/a12028.html

In other cases the headers provide inline member function definitions,
but when processed by Doxygen the class name "PB_DS_CLASS_C_DEC" is not
recognised.

This patch makes Doxygen ignore definitions that only make sense when
included in the right context with the right macros defined.

5 years agoUpdate libstdc++ Doxygen config
Jonathan Wakely [Thu, 2 May 2019 15:44:16 +0000 (16:44 +0100)]
Update libstdc++ Doxygen config

The GROUP_NESTED_COMPOUNDS option means that types nested inside inline
namespaces or other classes will be automatically added to a Doxygen
group, e.g. this actually works as intended:

  /**
   * @defgroup chrono Time
   * @ingroup utilities
   *
   * Classes and functions for time.
   * @{
   */

  namespace chrono
  {
    template<typename _Rep, typename _Period = ratio<1>>
      struct duration;

    template<typename _Clock, typename _Dur = typename _Clock::duration>
      struct time_point;
  }

  /// @}

Currently chrono::duration and chrono::time_point are not added to the
"chrono" group. They would need an explicit @ingroup tag added to them
individually. With GROUP_NESTED_COMPOUNDS=YES they get added to the
enclosing group.

The SORT_BY_SCOPE_NAME option means that the list of classes will sort
by class name, not the full qualified-id. Currently the alphabetical
Class List for classes beginning with 'c' looks like:

  char_traits (__gnu_cxx)
  character (__gnu_cxx)
  condition_base (__gnu_cxx)
  const_iterator_
  condition_variable_any (std::_V2)
  cauchy_distribution (std)
  char_traits (std)

i.e. the list is sorted by the namespaces first, then the class names.
This is not helpful when you don't know which namespace a class might be
in, and inline namespaces with reserved names are not hidden (see
https://github.com/doxygen/doxygen/issues/5914 for a feature request to
allow that).

With SORT_BY_SCOPE_NAME=NO the list looks like:

  cauchy_distribution (std)
  char_traits (__gnu_cxx)
  char_traits (std)
  character (__gnu_cxx)
  condition_base (__gnu_cxx)
  condition_variable_any (std::_V2)
  const_iterator_

This allows you to find a class by name more easily.

Also add PREDEFINED macros so that __attribute__ and various macros like
_GLIBCXX_NO_DISCARD, _GLIBCXX14_CONSTEXPR don't appear in the generated
docs.

* doc/doxygen/user.cfg.in: Regenerate with Doxygen 1.8.14 and set
GROUP_NESTED_COMPOUNDS=YES and SORT_BY_SCOPE_NAME=NO. Add various
_GLIBCXX_xxx macros and __attribute__(X) to PREDEFINED macros that
Doxygen expands.

[Aarch64][SVE] Dot product support

This patch does two things. For the general vectoriser, it adds support to
perform fully masked reductions over expressions that don't support masking.
This is achieved by using VEC_COND_EXPR where possible.  At the moment this is
implemented for DOT_PROD_EXPR only, but the framework is there to extend it to
other expressions.

Related to that, this patch adds support to vectorize dot product using SVE.  It
also uses the new functionality to ensure that the resulting loop is masked.

Given this input code:

uint32_t
dotprod (uint8_t *restrict x, uint8_t *restrict y, int n)
{
  uint32_t sum = 0;

  for (int i = 0; i < n; i++)
    {
      sum += x[i] * y[i];
    }

  return sum;
}

The resulting SVE code is:

0000000000000000 <dotprod>:
   0: 7100005f  cmp w2, #0x0
   4: 5400024d  b.le 4c <dotprod+0x4c>

5 years agocompiler,runtime: do more direct interfaces
Ian Lance Taylor [Wed, 1 May 2019 21:34:16 +0000 (21:34 +0000)]
compiler,runtime: do more direct interfaces

    A direct interface is an interface whose data word contains the
    actual data value, instead of a pointer to it. The gc toolchain
    creates a direct interface if the value is pointer shaped, that
    includes pointers (including unsafe.Pointer), functions, channels,
    maps, and structs and arrays containing a single pointer-shaped
    field. In gccgo, we only do this for pointers. This CL unifies
    direct interface types with gc. This reduces allocations when
    converting such types to interfaces.

    Our method functions used to always take pointer receivers, to
    make interface calls easy. Now for direct interface types, their
    value methods will take value receivers. For a pointer to those
    types, when converted to interface, the interface data contains
    the pointer. For that interface to call a value method, it will
    need a wrapper method that dereference the pointer and invokes
    the value method. The wrapper method, instead of the actual one,
    is put into the itable of the pointer type.

    In the runtime, adjust funcPC for the new layout of interfaces of
    functions.

5 years agoruntime: persistentalloc and cache itabs
Ian Lance Taylor [Wed, 1 May 2019 20:27:36 +0000 (20:27 +0000)]
runtime: persistentalloc and cache itabs

    Previously, each time we do an interface conversion for which the
    method table is not known at compile time, we allocate a new
    method table.

    This CL ports the mechanism of itab caching from the gc runtime,
    adapted to our itab representation and method finding mechanism.
    With the cache, we reuse the same itab for the same (interface,
    concrete) type pair. This reduces allocations in interface
    conversions.

    Unlike the gc runtime, we don't prepopulate the cache with
    statically allocated itabs, as currently we don't have a way to
    find them. This means we don't deduplicate run-time allocated
    itabs with compile-time allocated ones. But that is not too bad
    -- it is just a cache anyway.

    As now itabs are never freed, it is also possible to drop the
    write barrier for writing the first word of an interface header.
    I'll leave this optimization for the future.

Ok for trunk and to backport to all release branches ?

Tested with a simple build and a smoke test.

Fix filesystem::path tests

The root_path.cc test had some debugging macros left in accidentally, so
didn't FAIL correctly if an assertion failed.

The string-char8_t.cc tests didn't compile on Windows.

* testsuite/27_io/filesystem/path/decompose/root_path.cc: Remove
macros accidentally left in.
