MPFR on old but still supported operating systems like SLES 12 (MPFR
3.1.2) or RHEL/CentOS 7.x (MPFR 3.1.1).

4 years ago[C] Opt out of GNU vector extensions for built-in SVE types
Richard Sandiford [Fri, 8 Nov 2019 08:35:55 +0000 (08:35 +0000)]
[C] Opt out of GNU vector extensions for built-in SVE types

The AArch64 port defines built-in SVE types at start-up under names
like __SVInt8_t.  These types are represented in the front end and
gimple as normal VECTOR_TYPEs and are code-generated as normal vectors.
However, we'd like to stop the frontends from treating them in the
same way as GNU-style ("vector_size") vectors, for several reasons:

(1) We allowed the GNU vector extensions to be mixed with Advanced SIMD
    vector types and it ended up causing a lot of confusion on big-endian
    targets.  Although SVE handles big-endian vectors differently from
    Advanced SIMD, there are still potential surprises; see the block
    comment near the head of aarch64-sve.md for details.

(2) One of the SVE vectors is a packed one-bit-per-element boolean vector.
    That isn't a combination the GNU vector extensions have supported
    before.  E.g. it means that vectors can no longer decompose to
    arrays for indexing, and that not all elements are individually
    addressable.  It also makes it less clear which order the initialiser
    should be in (lsb first, or bitfield ordering?).  We could define
    all that of course, but it seems a bit weird to go to the effort
    for this case when, given all the other reasons, we don't want the
    extensions anyway.

(3) The GNU vector extensions only provide full-vector operations,
    which is a very artifical limitation on a predicated architecture
    like SVE.

(4) The set of operations provided by the GNU vector extensions is
    relatively small, whereas the SVE intrinsics provide many more.

(5) It makes it easier to ensure that (with default options) code is
    portable between compilers without the GNU vector extensions having
    to become an official part of the SVE intrinsics spec.

(6) The length of the SVE types is usually not fixed at compile time,
    whereas the GNU vector extension is geared around fixed-length
    vectors.

    It's possible to specify the length of an SVE vector using the
    command-line option -msve-vector-bits=N, but in principle it should
    be possible to have functions compiled for different N in the same
    translation unit.  This isn't supported yet but would be very useful
    for implementing ifuncs.  Once mixing lengths in a translation unit
    is supported, the SVE types should represent the same type throughout
    the translation unit, just as GNU vector types do.

However, when -msve-vector-bits=N is in effect, we do allow conversions
between explicit GNU vector types of N bits and the corresponding SVE
types.  This doesn't undermine the intent of (5) because in this case
the use of GNU vector types is explicit and intentional.  It also doesn't
undermine the intent of (6) because converting between the types is just
a conditionally-supported operation.  In other words, the types still
represent the same types throughout the translation unit, it's just that
conversions between them are valid in cases where a certain precondition
is known to hold.  It's similar to the way that the SVE vector types are
defined throughout the translation unit but can only be used in functions
for which SVE is enabled.

The patch adds a new flag to tree_type_common to select this behaviour.
(We currently have 17 bits free.)  To avoid making the flag too specific
to vectors, I called it TYPE_INDIVISIBLE_P, to mean that the frontend
should not allow the components of the type to be accessed directly.
This could perhaps be useful in future for hiding the fact that a
type is an array, or for hiding the fields of a record or union.

The actual frontend changes are very simple, mostly just replacing
VECTOR_TYPE_P with gnu_vector_type_p in selected places.

One interesting case is:

  /* Need to convert condition operand into a vector mask.  */
  if (VECTOR_TYPE_P (TREE_TYPE (ifexp)))
    {
      tree vectype = TREE_TYPE (ifexp);
      tree elem_type = TREE_TYPE (vectype);
      tree zero = build_int_cst (elem_type, 0);
      tree zero_vec = build_vector_from_val (vectype, zero);
      tree cmp_type = build_same_sized_truth_vector_type (vectype);
      ifexp = build2 (NE_EXPR, cmp_type, ifexp, zero_vec);
    }

in build_conditional_expr.  This appears to be trying to support
elementwise conditions like "vec1 ? vec2 : vec3", which is something
the C++ frontend supports.  However, this code can never trigger AFAICT,
because "vec1" does not survive c_objc_common_truthvalue_conversion:

    case VECTOR_TYPE:
      error_at (location, "used vector type where scalar is required");
      return error_mark_node;

Even if it did, the operation should be a VEC_COND_EXPR rather
than a COND_EXPR.

I've therefore left that condition as-is, but added tests for the
"vec1 ? vec2 : vec3" case to make sure that we don't accidentally
allow it for SVE vectors in future.

4 years agoGeneralise gather and scatter optabs
Richard Sandiford [Fri, 8 Nov 2019 08:32:19 +0000 (08:32 +0000)]
Generalise gather and scatter optabs

The gather and scatter optabs required the vector offset to be
the integer equivalent of the vector mode being loaded or stored.
This patch generalises them so that the two vectors can have different
element sizes, although they still need to have the same number of
elements.

One consequence of this is that it's possible (if unlikely)
for two IFN_GATHER_LOADs to have the same arguments but different
return types.  E.g. the same scalar base and vector of 32-bit offsets
could be used to load 8-bit elements and to load 16-bit elements.
From just looking at the arguments, we could wrongly deduce that
they're equivalent.

I know we saw this happen at one point with IFN_WHILE_ULT,
and we dealt with it there by passing a zero of the return type
as an extra argument.  Doing the same here also makes the load
and store functions have the same argument assignment.

For now this patch should be a no-op, but later SVE patches take
advantage of the new flexibility.

4 years agoExpand C2x attribute parsing support and factor out from TM attributes.
Joseph Myers [Thu, 7 Nov 2019 23:54:49 +0000 (23:54 +0000)]
Expand C2x attribute parsing support and factor out from TM attributes.

There is one place in the C parser that already handles a subset of
the C2x [[]] attribute syntax: c_parser_transaction_attributes.

This patch factors C2x attribute parsing out of there, extending it to
cover the full C2x attribute syntax (although currently only called
from that one place in the parser - so this is another piece of
preparation for supporting C2x attributes in the places where C2x says
they are valid, not the patch that actually enables such support).
The new C2X attribute parsing code uses the same representation for
scoped attributes as C++ does, so requiring parse_tm_stmt_attr to
handle the scoped attributes representation (C++ currently
special-cases TM attributes "to avoid the pedwarn in C++98 mode"; in C
I'm using an argument to c_parser_std_attribute_specifier to disable
the pedwarn_c11 call in the TM case).

Parsing of arguments to known attributes is shared by GNU and C2x
attributes.  C2x specifies that unknown attributes are ignored (GCC
practice in such a case is to warn along with ignoring the attribute)
and gives a very general balanced-token-sequence syntax for arguments
to unknown attributes (known ones each have their own syntax which is
a subset of balanced-token-sequence), so support is added for parsing
and ignoring such balanced-token-sequences as arguments of unknown
attributes.

Some limited tests are added of different attribute usages in the TM
attribute case.  The cases that become valid in the TM case include
extra commas inside [[]], and an explicit "gnu" namespace, as the
extra commas have no semantic effect for C2x attributes, while
accepting the "gnu" namespace seems appropriate because the attribute
in question is accepted inside __attribute__ (()), which is considered
equivalent to the "gnu" namespace inside [[]].

4 years agoIBM Z: Add pattern for load truth value of comparison into reg

IBM Z: Add pattern for load truth value of comparison into reg

The RTXs used to express an overflow condition check in add/sub/mul are
too complex for if conversion.  However, there is code in
noce_emit_store_flag which generates a simple CC compare as the base
for using a conditional load.  All we have to do is to provide a
pattern to store the truth value of a CC compare into a GPR.

Done with the attached patch.
