Reject versioning for alignment with different masks (PR 92526)

Allowing mixed vector sizes broke the assumption in the following assert,
since it's now possible for different accesses to require different
levels of alignment:

              /* FORNOW: use the same mask to test all potentially unaligned
                 references in the loop.  The vectorizer currently supports
                 a single vector size, see the reference to
                 GET_MODE_NUNITS (TYPE_MODE (vectype)) where the
                 vectorization factor is computed.  */
              gcc_assert (!LOOP_VINFO_PTR_MASK (loop_vinfo)
                          || LOOP_VINFO_PTR_MASK (loop_vinfo) == mask);

I guess we could try to over-align smaller accesses so that all
of them are consistent, or try to support multiple alignment masks,
but for now the easiest fix seems to be to turn the assert into a
bail-out check.

5 years agoAdd more markup to vect-alias-check-{1,18}.c (PR 92543)

Add more markup to vect-alias-check-{1,18}.c (PR 92543)

In vect-alias-check-1.c we unroll the inner loop and then vectorise
the stores at a[c + 1][b].  Since the access has no guaranteed
alignemnt, we need a realignment mechanism or support for unaligned
accesses in order to vectorise.

In vect-alias-check-18.c we use a reverse access and so need
permute support in order to vectorise.

I'm not really sure when this part of the testsuite prefers
{ xfail { ! foo } } and when it prefers { target foo }.  xfail
seems like the most common choice for the alignment restriction,
whereas vect_int and vect_perm are mostly dg-require-effective-target
style features, so I went with that combination.

jit: fix ICE with GCC_JIT_BOOL_OPTION_SELFCHECK_GC since r278084 (PR jit/92483)

Since r278084 (part of the params refactoring), most of libgccjit's
test suite has been ICEing.

The root cause is that jit-playback.c injects params to its fake_args
here:

  /* Aggressively garbage-collect, to shake out bugs: */
  if (get_bool_option (GCC_JIT_BOOL_OPTION_SELFCHECK_GC))
    {
      ADD_ARG ("--param");
      ADD_ARG ("ggc-min-expand=0");
      ADD_ARG ("--param");
      ADD_ARG ("ggc-min-heapsize=0");
    }

(building a vec of char * where the char * are allocated using xstrdup)

and r278084 added this logic to decode_cmdline_options_to_array:

964       /* Interpret "--param" "key=name" as "--param=key=name".  */
965       const char *needle = "--param";
966       if (i + 1 < argc && strcmp (opt, needle) == 0)
967 {
968   const char *replacement
969     = opts_concat (needle, "=", argv[i + 1], NULL);
970   argv[++i] = replacement;
971 }

Note that at line 970 it manipulates the argv in-place, inserting a
new option allocated with opts_concat, which uses opts_obstack
(itself initialized from toplev::main).

jit-playback.c cleans up its fake arguments using "free", at which
point we have a free of the middle of an obstack and an ICE.

This patch fixes the issue by using the new syntax for the params.

Fixes all 60 FAILs in jit.sum, restoring the number of PASS results
from 2033 to 10469.

5 years agoAdd more pedwarns for [[]] C attributes on types.
Joseph Myers [Wed, 20 Nov 2019 00:13:51 +0000 (00:13 +0000)]
Add more pedwarns for [[]] C attributes on types.

The standard [[]] attributes currently defined in C2x are all not
valid on types not being defined at the time.

Use on such types results in a warning from attribs.c about attributes
appertaining to types (the warning that I think is bogus in general
for both C and C++, applying as it does to all [[]] attributes
including gnu:: ones that are perfectly meaningful on types not being
defined and work fine when __attribute__ syntax is used instead).  If
that warning is removed (as I intend to do in a subsequent patch),
warnings may or may not result from the attribute handlers, depending
on whether those particular attribute handlers consider the attributes
meaningful in such a context.  In C, however, the rules about where
each [[]] attribute is valid are constraints, so a pedwarn, not a
warning, is required.

Because some handlers are shared between standard and gnu::
attributes, there can be cases that are valid for the GNU attribute
variant but not for the standard one.  So in general it is not correct
to rely on the attribute handlers to give all required pedwarns
(although in some cases, a pedwarn in the attribute handler is in
appropriate way of diagnosing an invalid use); they not have the
information about whether the attribute was a gnu:: one and can
legitimately accept a wider range of uses for the gnu:: attributes.

This patch ensures appropriate diagnostics for invalid uses of C2x
standard attributes on types, and so helps pave the way for the
subsequent removal of the bogus check in attribs.c, by adding a check
run in the front end before calling decl_attributes; this check
removes the attributes from the list after calling pedwarn to avoid
subsequent duplicate warnings.

Change some bad uses of C2x attributes into pedwarns.

Certain bad uses of C2x standard attributes (that is, attributes
inside [[]] with only a name but no namespace specified) are
constraint violations, and so should be diagnosed with a pedwarn (or
error) where GCC currently uses a warning.  This patch implements this
in some cases (not yet for attributes used on types, nor for some bad
uses of fallthrough attributes).  Specifically, this applies to
unknown standard attributes (taking care not to pedwarn for nodiscard,
which is known but not implemented for C), and to all currently
implemented standard attributes in attribute declarations (including
when mixed with fallthrough) and on statements.

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

gcc/c:
* c-decl.c (c_warn_unused_attributes): Use pedwarn not warning for
standard attributes.
* c-parser.c (c_parser_std_attribute): Take argument for_tm.  Use
pedwarn for unknown standard attributes and return error_mark_node
for them.

gcc/c-family:
* c-common.c (attribute_fallthrough_p): In C, use pedwarn not
warning for standard attributes mixed with fallthrough attributes.
