2012-06-13Add -isystem-prefix and -ino-system-prefix arguments, which can be used toRichard Smith
override whether headers are system headers by checking for prefixes of the header name specified in the #include directive.

2012-06-13Rename shouldVisitImplicitDeclarations to shouldVisitImplicitCode.Daniel Jasper
Fix RecursiveASTVisitor to visit CXXForRangeStmts accordingly to visit implicit or explicit code.

2012-06-12Revert "[analyzer] Treat LValueBitCasts like regular pointer bit casts."Jordan Rose
This does not actually give us the right behavior for reinterpret_cast of references. Reverting so I can think about it some more. This reverts commit 50a75a6e26a49011150067adac556ef978639fe6. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158341 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-11[analyzer] Treat LValueBitCasts like regular pointer bit casts.Jordan Rose
These casts only appear in very well-defined circumstances, in which the target of a reinterpret_cast or a function formal parameter is an lvalue reference. According to the C++ standard, the following are equivalent: reinterpret_cast<T&>( x) *reinterpret_cast<T*>(&x) [expr.reinterpret.cast]p11 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158338 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-11Add PPC support for translating gcc-style -mcpu options into LLVM ↵Hal Finkel
-target-cpu options. This functionality is based on what is done on ARM, and enables selecting PPC CPUs in a way compatible with gcc's driver. Also, mirroring gcc (and what is done on x86), -mcpu=native support was added. This uses the host cpu detection from LLVM (which will also soon be updated by refactoring code currently in backend). In order for this to work, the target needs a list of valid CPUs -- we now accept all CPUs accepted by LLVM. A few preprocessor defines for common CPU types have been added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158334 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-11[analyzer] Add ObjCLoopChecker: objects from NSArray et al are non-nil.Jordan Rose
While collections containing nil elements can still be iterated over in an Objective-C for-in loop, the most common Cocoa collections -- NSArray, NSDictionary, and NSSet -- cannot contain nil elements. This checker adds that assumption to the analyzer state. This was the cause of some minor false positives concerning CFRelease calls on objects in an NSArray. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158319 91177308-0d34-0410-b5e6-96231b3b80d8

such as "protocol" and "expression" being implicitly turned into links to mistakenly-generated Doxygen pages: - Escaping @ symbols when Doxygen would otherwise incorrectly interpret them; - Escaping # symbols when they're not intended as explicit Doxygen link requests, such as when discussing preprocessor directives; - In one odd case, unescaping @ in @__experimental_modules_import, because Doxygen wrote '\@' to the output in that case, causing the example in the description of ImportDecl to be wrong; and - Fixing a typo: @breif -> @brief. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158299 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-10Remove CXXRecordDecl flags which are unused after r158289.Richard Smith
We need an efficient mechanism to determine whether a defaulted default constructor is constexpr, in order to determine whether a class is a literal type, so keep the incrementally-built form on CXXRecordDecl. Remove the on-demand computation of same, so that we only have one method for determining whether a default constructor is constexpr. This doesn't affect correctness, since default constructor lookup is much simpler than selecting a constructor for copying or moving. We don't need a corresponding mechanism for defaulted copy or move constructors, since they can't affect whether a type is a literal type. Conversely, checking whether such functions are constexpr can require non-trivial effort, so we defer such checks until the copy or move constructor is required. Thus we now only compute whether a copy or move constructor is constexpr on demand, and only compute whether a default constructor is constexpr in advance. This is unfortunate, but seems like the best solution. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158290 91177308-0d34-0410-b5e6-96231b3b80d8
