[AArch64] Add partial SVE vector modes

the memory vector involved in an extending load or truncating store.

5 years agoRename attribute-related functions and productions in C parser.
Joseph Myers [Tue, 15 Oct 2019 00:12:49 +0000 (01:12 +0100)]
Rename attribute-related functions and productions in C parser.

The C2x attribute syntax, [[ ]], appears in different places in the
syntax from GNU __attribute__, and, where they can appear in the same
place in the syntax, they do not always appertain to the same entity.
(For example, in "int func(void) ATTRS;", GNU attributes appertain to
the declaration but C2x attributes appertain to the function type.)

Thus, the C parser needs to handle the two kinds of attributes
separately, with each place in the syntax accepting whatever kinds of
attributes are appropriate there and applying them to the relevant
entities.  This patch prepares for this by renaming parser functions
relating to attributes to make clear they are specifically about GNU
attributes and renaming syntax productions likewise to avoid confusing
with the C2x attributes syntax productions.

Where comments refer to attributes, this has only be changed where it
is clear that in the context they are referring specifically to the
gnu-attributes syntax.  There may be other places that also end up
changing to refer to gnu-attributes as part of the C2x attributes
implementation, if more detailed examination of those places shows
they are also specific to gnu-attributes.  (I do not expect code
dealing with semantics of attributes outside of the parser to need to
change; as for C++, it will be possible to use existing attributes
inside [[]] with the gnu:: form of the attribute name.)

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

[ARM] Switch to default sched pressure algorithm

Currently the Arm backend selects the alternative sched pressure algorithm.
The issue is that this doesn't take register pressure into account, and so
it causes significant additional spilling on Arm where there are only 14
allocatable registers.  Building SPEC2006 showed significant codesize gains
with the default pressure algorithm, so switch back to that.  PR77308 shows
~800 fewer instructions.

5 years ago[C] Avoid exposing internal details in aka types
Richard Sandiford [Mon, 14 Oct 2019 08:05:52 +0000 (08:05 +0000)]
[C] Avoid exposing internal details in aka types

The current aka diagnostics can sometimes leak internal details that
seem more likely to be distracting than useful.  E.g. on aarch64:

  void f (va_list *va) { *va = 1; }

gives:

  incompatible types when assigning to type ‘va_list’ {aka ‘__va_list’} from type ‘int’

where __va_list isn't something the user is expected to know about.
A similar thing happens for C++ on the arm_neon.h-based:

  float x;
  int8x8_t y = x;

which gives:

  cannot convert ‘float’ to ‘int8x8_t’ {aka ‘__Int8x8_t’} in initialization

This is accurate -- and __Int8x8_t is defined by the AArch64 PCS --
but it's not going to be meaningful to most users.

This patch stops the aka code looking through typedefs if all of
the following are true:

(1) the typedef is built into the compiler or comes from a system header

(2) the target of the typedef is anonymous or has a name in the
    implementation namespace

(3) the target type is a tag type or vector type, which have in common that:
    (a) we print their type names if they have one
    (b) what we print for anonymous types isn't all that useful
        ("struct <anonymous>" etc. for tag types, pseudo-C "__vector(N) T"
        for vector types)

The patch does this by recursively looking for the aka type, like the
C++ frontend already does.  This in turn makes "aka" work for distinct type
copies like __Int8x8_t on aarch64, fixing the ??? in aarch64/diag_aka_1.c.

[Darwin, machopic 8/n] Back out part of PR71767 fix.

We applied a conservative, but fairly large, hammer to fix PR71767.
However, ideally, we want minimise the number of symbols visible to
ld64 and to match the cases emitted by clang (since that's what ld64
is expecting).  Now we've improved the handling of indirections, we
can make the indirection symbols local when they are in the regular
non-lazy symbol pointers section.  We will continue to make any
indirections in the data section visible (since right now we have no
way to track if a given symbol follows a weak global).
This change makes no difference to handling of labels for constants
(to be revised in a future patch).

There's a mechanical change to a number of tests (allowing 'l' or 'L'

[Darwin, machopic 6/n] Fix for 67183

When we're using the LLVM-based assembler (the default on modern Darwin)
the ordering of stubs and non-lazy symbol pointers is important.

Interleaving the output (current GCC behaviour) leads to crashes which
prevents us from building code with symbol stubs.

To resolve this, we order the output of stubs and symbol indirections:

 1. Any indirections in the data section
 2. Symbol stubs.
 3. Non-lazy symbol pointers.

At present, we still emit LTO sections after these.

This patch accordingly makes GCC accept the _Decimal* keywords in
strict C2x mode, using pedwarn_c11 to get a warning for
-Wc11-c2x-compat.  (Constants, where the pedwarn is in libcpp, will be
dealt with separately.)

The _Decimal* keywords are marked with D_EXT, meaning they are not
considered keywords at all in strict conformance modes.  This is
contrary to the normal practice for most implementation-namespace
keywords, which are accepted in all standards modes but with
appropriate pedwarns for older standards.  This patch removes D_EXT
from those keywords so they are accepted as keywords for all
standards, consequently removing the gcc.dg/dfp/keywords-ignored-c99.c
test that is no longer valid.

(A new D_C2X for keywords will still be needed if any new keywords get
added that aren't in the implementation namespace for older standards;
there are proposals for such keywords, albeit as predefined macros
that might not actually need new keywords in the compiler in all
cases.  If the DFP keywords end up as decimal32 etc., of course
appropriate compiler and testcase changes will be needed, and a
version of keywords-ignored-c99.c would make sense again with such
spellings.)

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

gcc/c:
* c-decl.c (declspecs_add_type): Use pedwarn_c11 for DFP types.

gcc/c-family:
* c-common.c (c_common_reswords): Do not use D_EXT for _Decimal32,
_Decimal64 and _Decimal128.

gcc/testsuite:
* gcc.dg/dfp/c11-keywords-1.c, gcc.dg/dfp/c11-keywords-2.c,
gcc.dg/dfp/c2x-keywords-1.c, gcc.dg/dfp/c2x-keywords-2.c: New
tests.
* gcc.dg/dfp/keywords-ignored-c99.c: Remove test.
* gcc.dg/dfp/constants-c99.c, gcc.dg/dfp/keywords-c89.c,
gcc.dg/dfp/keywords-c99.c: Use -pedantic-errors.
