Make more bad uses of fallthrough attribute into pedwarns.

Various bad uses of the [[fallthrough]] attribute are constraint
violations in C2x, so need pedwarns rather than warnings.

This patch duly turns the relevant warnings into pedwarns.  The
relevant code is not specific to C, and does not know which form the
attribute was given in ([[fallthrough]] or [[gnu::fallthrough]] or
__attribute__((fallthrough))), but as I understand it these usages are
also erroneous for C++ and it seems reasonable to give a pedwarn here
even when a form other than [[fallthrough]] is being used.

The precise meaning of the standard wording about "The next statement
that would be executed" seems a but unclear in some corner cases; the
tests added keep to cases where it is clear whether or not the next

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

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,

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.
