This is a follow-up to r224915. This adds a bit more line noise to the tests
added in that revision to make sure the parser is ready for a toplevel decl
after each incorrect line. Use this to move the tests up to where they belong.
This uncovered that the early return was missing a call to
ActOnTagDefinitionError(), so add that. (Also fixes at least one of the crashes
on SLi's bot.)
llvm-svn: 224958
r168626 added nicer diagnostics for attributes in the wrong places, such as
after the `final` on a class. To do this, it added code that did high-level
pattern matching for e.g. 'final' 'alignas' '(' and then skipped until the
closing ')'. If it saw that, it then went down the regular class parsing
path and then called MaybeParseCXX11Attributes() to parse the attribute after
the 'final' using real attribute parsing code. On invalid attributes, the
real attribute parsing code could eat more tokens than the pattern matching
code and for example skip past the '{' starting the class, which would then
lead to an assert. To prevent this, check for a good state after calling
MaybeParseCXX11Attributes() (which morphed into CheckMisplacedCXX11Attribute()
in r175575) and bail out if things look bleak.
Found by SLi's afl bot.
llvm-svn: 224915
Fixes this snippet from SLi's afl fuzzer output:
class {
i (x = <, enum
This parsed i as a function, x as a paramter, and the stuff after < as a
template list. This then called TryConsumeDeclarationSpecifier() which
called TryAnnotateCXXScopeToken() without checking the preconditions of
this function. Check them before calling, like all other callers of
TryAnnotateCXXScopeToken() do.
A more readable reproducer that causes the same crash is
class {
void i(int x = MyTemplateClass<int, union int>::foo());
};
The reduced version used an eof token as surprising token, but kw_int works
just as well to repro and is easier to insert into a test file.
llvm-svn: 224906
isDeclarationSpecifier performs error recovers which jostles the token
stream. Specifically, TryAnnotateTypeOrScopeToken will end up consuming
a typename token which will confuse the attribute parsing machinery as
we no-longer have something identifier-like.
llvm-svn: 224903
ParseCXXNonStaticMemberInitializer stashes away all the tokens for the
initializer and an additional EOF token to denote where the initializer
ends. However, it is possible for ParseLexedMemberInitializer to get
its hands on the "real" EOF token; since the two tokens are
indistinguishable, we end up consuming the EOF and descend into madness.
Instead, make it possible to tell which EOF token we are looking at.

This allows 'namespace A::B { ... }' as a shorthand for 'namespace A {
namespace B { ... } }'. We already supported this correctly for error recovery;
promote that support to a full implementation.
This is not the right implementation: we do not maintain source fidelity
because we desugar the nested namespace definition in the parser. This is
tricky to avoid, since the definition genuinely does inject one named
entity per level in the namespace name.
llvm-svn: 221574
This is a new form of expression of the form:
(expr op ... op expr)
where one of the exprs is a parameter pack. It expands into
(expr1 op (expr2onwards op ... op expr))
(and likewise if the pack is on the right). The non-pack operand can be
omitted; in that case, an empty pack gives a fallback value or an error,
depending on the operator.
llvm-svn: 221573
Now that we have initial support for VSX, we can begin adding
intrinsics for programmer access to VSX instructions. This patch
performs the necessary enablement in the front end, and tests it by
implementing intrinsics for minimum and maximum using the vector
double data type.
The main change in the front end is to no longer disallow "vector" and
"double" in the same declaration (lib/Sema/DeclSpec.cpp), but "vector"
and "long double" must still be disallowed. The new intrinsics are
accessed via vec_max and vec_min with changes in
lib/Headers/altivec.h. Note that for v4f32, we already access
corresponding VMX builtins, but with VSX enabled we should use the
forms that allow all 64 vector registers.
The new built-ins are defined in include/clang/Basic/BuiltinsPPC.def.
I've added a new test in test/CodeGen/builtins-ppc-vsx.c that is
similar to, but much smaller than, builtins-ppc-altivec.c. This
allows us to test VSX IR generation without duplicating CHECK lines
for the existing bazillion Altivec tests.
Since vector double is now legal when VSX is available, I've modified
the error message, and changed where we test for it and for vector
long double, since the target machine isn't visible in the old place.
This serendipitously removed a not-pertinent warning about 'long'
being deprecated when used with 'vector', when "vector long double" is
encountered and we just want to issue an error. The existing tests
test/Parser/altivec.c and test/Parser/cxx-altivec.cpp have been
updated accordingly, and I've added test/Parser/vsx.c to verify that
"vector double" is now legitimate with VSX enabled.
There is a companion patch for LLVM.

Due to statement expressions supported as GCC extension, it is possible
to put 'break' or 'continue' into a loop/switch statement but outside
its body, for example:
for ( ; ({ if (first) { first = 0; continue; } 0; }); )
This code is rejected by GCC if compiled in C mode but is accepted in C++
code. GCC bug 44715 tracks this discrepancy. Clang used code generation
that differs from GCC in both modes: only statement of the third
expression of 'for' behaves as if it was inside loop body.
This change makes code generation more close to GCC, considering 'break'
or 'continue' statement in condition and increment expressions of a
loop as it was inside the loop body. It also adds error for the cases
when 'break'/'continue' appear outside loop due to this syntax. If
code generation differ from GCC, warning is issued.

Fixes <rdar://problem/15584219> and <rdar://problem/12241361>.
This change looks large, but all it does is reuse and consolidate
the delayed diagnostic logic for deprecation warnings with unavailability
warnings. By doing so, it showed various inconsistencies between the
diagnostics, which were close, but not consistent. It also revealed
some missing "note:"'s in the deprecated diagnostics that were showing
up in the unavailable diagnostics, etc.
This change also changes the wording of the core deprecation diagnostics.
Instead of saying "function has been explicitly marked deprecated"
we now saw "'X' has been been explicitly marked deprecated". It
turns out providing a bit more context is useful, and often we
got the actual term wrong or it was not very precise
(e.g., "function" instead of "destructor"). By just saying the name
of the thing that is deprecated/deleted/unavailable we define
this issue away. This diagnostic can likely be further wordsmithed
to be shorter.

Previously, a line like
// expected-error-re {{foo}}
treats the entirety of foo as a regex. This is inconvenient when matching type
names containing regex characters. For example, to match
"void *(class test8::A::*)(void)" inside such a regex, one would have to type
"void \*\(class test8::A::\*\)\(void\)".
This patch changes the semantics of expected-error-re to only treat the parts
of the directive wrapped in double curly braces as regexes. This avoids the
escaping problem and leads to nicer patterns for those cases; see e.g. the
change to test/Sema/format-strings-scanf.c.
(The balanced search for closing }} of a directive also makes us handle the
full directive in test\SemaCXX\constexpr-printing.cpp:41 and :53.)
