2013-05-03When building a module, forward diagnostics to the outer diagnostic consumer.Douglas Gregor
Previously, we would clone the current diagnostic consumer to produce a new diagnostic consumer to use when building a module. The problem here is that we end up losing diagnostics for important diagnostic consumers, such as serialized diagnostics (where we'd end up with two diagnostic consumers writing the same output file). With forwarding, the diagnostics from all of the different modules being built get forwarded to the one serialized-diagnostic consumer and are emitted in a sane way.

2013-05-03Support __wchar_t in -fms-extensions and -fms-compatibility modes.Hans Wennborg
MSVC provides __wchar_t, either as an alias for the built-in wchar_t type, or as a separate type depending on language (C vs C++) and flags (-fno-wchar). In -fms-extensions, Clang will simply accept __wchar_t as an alias for whatever type is used for wide character literals. In -fms-compatibility, we try to mimic MSVC's behavior by always making __wchar_t a builtin type. This fixes PR15815. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181004 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-03Correctly emit certain implicit references to 'self' even withinJohn McCall
a lambda. Bug #1 is that CGF's CurFuncDecl was "stuck" at lambda invocation functions. Fix that by generally improving getNonClosureContext to look through lambdas and captured statements but only report code contexts, which is generally what's wanted. Audit uses of CurFuncDecl and getNonClosureAncestor for correctness. Bug #2 is that lambdas weren't specially mapping 'self' when inside an ObjC method. Fix that by removing the requirement for that and using the normal EmitDeclRefLValue path in LoadObjCSelf. rdar://13800041 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181000 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-03[analyzer] Check the stack frame when looking for a var's initialization.Jordan Rose
FindLastStoreBRVisitor is responsible for finding where a particular region gets its value; if the region is a VarRegion, it's possible that value was assigned at initialization, i.e. at its DeclStmt. However, if a function is called recursively, the same DeclStmt may be evaluated multiple times in multiple stack frames. FindLastStoreBRVisitor was not taking this into account and just picking the first one it saw. <rdar://problem/13787723> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180997 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-03[analyzer] Fix trackNullOrUndef when tracking args that have nil receivers.Jordan Rose
There were actually two bugs here: - if we decided to look for an interesting lvalue or call expression, we wouldn't go find its node if we also knew we were at a (different) call. - if we looked through one message send with a nil receiver, we thought we were still looking at an argument to the original call. Put together, this kept us from being able to track the right values, which means sub-par diagnostics and worse false-positive suppression. Noticed by inspection. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180996 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-03Move parsing of identifiers in MS-style inline assembly intoJohn McCall
the actual parser and support arbitrary id-expressions. We're actually basically set up to do arbitrary expressions here if we wanted to. Assembly operands permit things like A::x to be written regardless of language mode, which forces us to embellish the evaluation context logic somewhat. The logic here under template instantiation is incorrect; we need to preserve the fact that an expression was unevaluated. Of course, template instantiation in general is fishy here because we have no way of delaying semantic analysis in the MC parser. It's all just fishy. I've also fixed the serialization of MS asm statements. This commit depends on an LLVM commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180976 91177308-0d34-0410-b5e6-96231b3b80d8

BugReporter. BugReporter is used to process ALL bug reports. By using a shared map, we are having mappings from different PathDiagnosticPieces to LocationContexts well beyond the point where we are processing a given report. This state is inherently error prone, and is analogous to using a global variable. Instead, just create a temporary map, one per report, and when we are done with it we throw it away.

2013-05-02Use attribute argument information to determine when to parse attribute ↵Douglas Gregor
arguments as expressions. This change partly addresses a heinous problem we have with the parsing of attribute arguments that are a lone identifier. Previously, we would end up parsing the 'align' attribute of this as an expression "(Align)": template<unsigned Size, unsigned Align> class my_aligned_storage { __attribute__((align((Align)))) char storage[Size]; }; while this would parse as a "parameter name" 'Align': template<unsigned Size, unsigned Align> class my_aligned_storage { __attribute__((align(Align))) char storage[Size]; }; The code that handles the alignment attribute would completely ignore the parameter name, so the while the first of these would do what's expected, the second would silently be equivalent to template<unsigned Size, unsigned Align> class my_aligned_storage { __attribute__((align)) char storage[Size]; }; i.e., use the maximal alignment rather than the specified alignment. Address this by sniffing the "Args" provided in the TableGen description of attributes. If the first argument is "obviously" something that should be treated as an expression (rather than an identifier to be matched later), parse it as an expression.

2013-05-02Use the Itanium ABI for thread_local on Darwin.Bill Wendling
After some discussion, it was decided to use the Itanium ABI for thread_local on Darwin OS X platforms. This involved a couple of changes. First, we use "_tlv_atexit" instead of "__cxa_thread_atexit". Secondly, the global variables are marked with 'internal' linkage, because we want all access to be calls to the Itanium-specific entry point, which has normal linkage. <rdar://problem/13733006> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180941 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-02When looking for the module associated with one of our magical builtin ↵Douglas Gregor
headers, speculatively load module maps. The "magical" builtin headers are the headers we provide as part of the C standard library, which typically comes from /usr/include. We essentially merge our headers into that location (due to cyclic dependencies). This change makes sure that, when header search finds one of our builtin headers, we figure out which module it actually lives in. This case is fairly rare; one ends up having to include one of the few built-in C headers we provide before including anything from /usr/include to trigger it.

2013-05-02Ensure that the line table for functions with cleanups is sequential.Adrian Prantl
If there is cleanup code, the cleanup code gets the debug location of the closing '}'. The subsequent ret IR-instruction does not get a debug location. The return _expression_ will get the debug location of the return statement. If the function contains only a single, simple return statement, the cleanup code may become the first breakpoint in the function.
