2013-02-14merge hasCLanguageLinkage and isExternC. Keep the shorter name.Rafael Espindola
I added hasCLanguageLinkage while fixing some language linkage bugs some time ago so that I wouldn't have to check all users of isExternC. It turned out to be a much longer detour than expected, but this patch finally merges the two again. The isExternC function now implements just the standard notion of having C language linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175119 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-14Add a getLanguageLinkage method to VarDecls and FunctionDecls. Use it to fixRafael Espindola
some cases where functions with no language linkage were being treated as having C language linkage. In particular, don't warn in extern "C" { static NonPod foo(); } Since getLanguageLinkage checks the language linkage, the linkage computation cannot use the language linkage. Break the loop by checking just the context in the linkage computation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175117 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-12Remove an assert which triggers when a decl context in a module hits the 'hasRichard Smith
lexical storage but not visible storage' case in C++. It's unclear whether we even need the special-case handling for C++, since it seems to be working around our not serializing a lookup table for the TU in C.

2013-02-09Ensure that type definitions present in just-loaded modules areDouglas Gregor
visible. The basic problem here is that a given translation unit can use forward declarations to form pointers to a given type, say, class X; X *x; and then import a module that includes a definition of X: import XDef; We will then fail when attempting to access a member of X, e.g., x->method() because the AST reader did not know to look for a default of a class named X within the new module. This implementation is a bit of a C-centric hack, because the only definitions that can have this property are enums, structs, unions, Objective-C classes, and Objective-C protocols, and all of those are either visible at the top-level or can't be defined later. Hence, we can use the out-of-date-ness of the name and the identifier-update mechanism to force the update. In C++, we will not be so lucky, and will need a more advanced solution, because the definitions could be in namespaces defined in two different modules, e.g., // module 1 namespace N { struct X; } // module 2 namespace N { struct X { /* ... */ }; } One possible implementation here is for C++ to extend the information associated with each identifier table to include the declaration IDs of any definitions associated with that name, regardless of context. We would have to eagerly load those definitions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174794 91177308-0d34-0410-b5e6-96231b3b80d8

Rewriting the same predicates over and over again is bad for code size and code maintainence.

2013-02-07[analyzer] Add pointer escape type param to checkPointerEscape callbackAnna Zaks
The checkPointerEscape callback previously did not specify how a pointer escaped. This change includes an enum which describes the different ways a pointer may escape. This enum is passed to the checkPointerEscape callback when a pointer escapes. If the escape is due to a function call, the call is passed. This changes previous behavior where the call is passed as NULL if the escape was due to indirectly invalidating the region the pointer referenced.

2013-02-07Fix handling of module imports adding names to a DeclContext after qualifiedRichard Smith
name lookup has been performed in that context (this probably only happens in C++). 1) Whenever we add names to a context, set a flag on it, and if we perform lookup and discover that the context has had a lookup table built but has the flag set, update all entries in the lookup table with additional names from the external source. 2) When marking a DeclContext as having external visible decls, mark the context in which lookup is performed, not the one we are adding. These won't be the same if we're adding another copy of a pre-existing namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174577 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-07Simplify FindExternalVisibleDeclsByName by making it return a bool indicatingRichard Smith
if it found any decls, rather than returning a list of found decls. This removes a returning-ArrayRef-to-deleted-storage bug from MultiplexExternalSemaSource (in code not exercised by any of the clang binaries), reduces the work required in the found-no-decls case with PCH, and importantly removes the need for DeclContext::lookup to be reentrant. No functionality change intended! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174576 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-07Introduce -fmodules-ignore-macro=NNN to ignore a macro when building/loading ↵Douglas Gregor
modules. The use of this flag enables a modules optimization where a given set of macros can be labeled as "ignored" by the modules system. Definitions of those macros will be completely ignored when building the module hash and will be stripped when actually building modules. The overall effect is that this flag can be used to drastically reduce the number of Eventually, we'll want modules to tell us what set of macros they respond to (the "configuration macros"), and anything not in that set will be excluded. However, that requires a lot of per-module information that must be accurate, whereas this option can be used more readily.

This can happen when one abuses precompiled headers by passing more -D options when using a precompiled hedaer than when it was built.

This was GCC's option to turn on UCN support, which we always have on now in C99 and C++ modes.

2013-02-06Optionally derive formatting information from the input file.Daniel Jasper
With this patch, clang-format can analyze the input file for two properties: 1. Is "int *a" or "int* a" more common. 2. Are non-C++03 constructs used, e.g. A<A<A>>. With Google-style, clang-format will now use the more common style for (1) and format C++03 compatible, unless it finds C++11 constructs in the input. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174504 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-06Adds a convenience function selectFirst to simplify matching.Manuel Klimek

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.

We found that findAll has been implemented incorrectly multiple times by various people using the matchers.
