2013-02-12The meat of this patch is in BuildCXXMemberCalLExpr where we make it useNick Lewycky
MarkMemberReferenced instead of marking functions referenced directly. An audit of callers to MarkFunctionReferenced and DiagnoseUseOfDecl also caused a few other changes: * don't mark functions odr-used when considering them for an initialization sequence. Do mark them referenced though. * the function nominated by the cleanup attribute should be diagnosed. * operator new/delete should be diagnosed when building a 'new' expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174951 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-06Remove unneeded test. We have plenty of subgroup relations between warnings,Ted Kremenek
and for those we care about we should have a general way of testing them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174531 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-05Change subexpressions to be visited in the CFG from left-to-right.Ted Kremenek
This is a more natural order of evaluation, and it is very important for visualization in the static analyzer. Within Xcode, the arrows will not jump from right to left, which looks very visually jarring. It also provides a more natural location for dataflow-based diagnostics. Along the way, we found a case in the analyzer diagnostics where we needed to indicate that a variable was "captured" by a block. -fsyntax-only timings on sqlite3.c show no visible performance change, although this is just one test case.

2013-02-02PR15132: Replace "address expression must be an lvalue or a functionRichard Smith
designator" diagnostic with more correct and more human-friendly "cannot take address of rvalue of type 'T'". For the case of & &T::f, provide a custom diagnostic, rather than unhelpfully saying "cannot take address of rvalue of type '<overloaded function type>'". For the case of &array_temporary, treat it just like a class temporary (including allowing it as an extension); the existing diagnostic wording for the class temporary case works fine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174262 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01[Sema][Attr]Fix alignment attribute printing.Michael Han
Remove "IsMSDeclspec" argument from Align attribute since the arguments in Attr.td should only model those appear in source code. Introduce attribute Accessor, and teach TableGen to generate syntax kind accessors for Align attribute, and use those accessors to decide if an alignment attribute is a declspec attribute. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174133 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-31Add indents to AST dumping and removed parenthesis from AST nodes.Richard Trieu

2013-01-30Also promote fp16 types to double when they're anonymous variadic arguments.Tim Northover
__fp16 isn't covered by the standard, but this resolves the oddity that float gets promoted when passed variadically, but not the smaller type. This is required by the AArch64 ABI, and a sane action elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173918 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-29Downgrade 'attribute ignored when parsing type' from error to warning, to matchRichard Smith
the diagnostic's warn_ name. Switch some places (notably C++11 attributes) which really wanted an error over to a different diagnostic. Finally, suppress the diagnostic entirely for __ptr32, __ptr64 and __w64, to avoid producing diagnostics in important system headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173788 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-29Replace AS_MSTypespec with AS_Keyword, for representing any attribute spelledRichard Smith
as a keyword. Rationalize existing attributes to use it as appropriate, and to not lie about some __declspec attributes being GNU attributes. In passing, remove a gross hack which was discarding attributes which we could handle. This results in us actually respecting the __pascal keyword again. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173746 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-24Handle universal character names and Unicode characters outside of literals.Jordan Rose
This is a missing piece for C99 conformance. This patch handles UCNs by adding a '\\' case to LexTokenInternal and LexIdentifier -- if we see a backslash, we tentatively try to read in a UCN. If the UCN is not syntactically well-formed, we fall back to the old treatment: a backslash followed by an identifier beginning with 'u' (or 'U'). Because the spelling of an identifier with UCNs still has the UCN in it, we need to convert that to UTF-8 in Preprocessor::LookUpIdentifierInfo. Of course, valid code that does *not* use UCNs will see only a very minimal performance hit (checks after each identifier for non-ASCII characters, checks when converting raw_identifiers to identifiers that they do not contain UCNs, and checks when getting the spelling of an identifier that it does not contain a UCN). This patch also adds basic support for actual UTF-8 in the source. This is treated almost exactly the same as UCNs except that we consider stray Unicode characters to be mistakes and offer a fixit to remove them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173369 91177308-0d34-0410-b5e6-96231b3b80d8
