2012-07-06Add -ffp-contract = { fast | on | off } command line option support.Lang Hames
This flag sets the 'fp-contract' mode, which controls the formation of fused floating point operations. Available modes are: - Fast: Form fused operations anywhere. - On: Form fused operations where allowed by FP_CONTRACT. This is the default mode. - Off: Don't form fused operations (in future this may be relaxed to forming fused operations where it can be proved that the result won't be affected). Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off' modes are equivalent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159794 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-06Implement AST classes for comments, a real parser for Doxygen comments and aDmitri Gribenko
very simple semantic analysis that just builds the AST; minor changes for lexer to pick up source locations I didn't think about before. Comments AST is modelled along the ideas of HTML AST: block and inline content. * Block content is a paragraph or a command that has a paragraph as an argument or verbatim command. * Inline content is placed within some block. Inline content includes plain text, inline commands and HTML as tag soup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159790 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-06[objcmt] Check for classes that accept 'objectForKey:' (or the other selectorsArgyrios Kyrtzidis
that the migrator handles) but return their instances as 'id', resulting in the compiler resolving 'objectForKey:' as the method from NSDictionary. When checking if we can convert to subscripting syntax, check whether the receiver is a result of a class method from a hardcoded list of such classes. In such a case return the specific class as the interface of the receiver. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159788 91177308-0d34-0410-b5e6-96231b3b80d8

actually perform value initialization rather than trying to fake it with a call to the default constructor. Fixes various bugs related to the previously-missing zero-initialization in this case.

2012-07-04Drop the ASTContext.h include from Stmt.h and fix up transitive users.Benjamin Kramer
This required moving the ctors for IntegerLiteral and FloatingLiteral out of line which shouldn't change anything as they are usually called through Create methods that are already out of line. ASTContext::Deallocate has been a nop for a long time, drop it from ASTVector and make it independent from ASTContext.h Pass the StorageAllocator directly to AccessedEntity so it doesn't need to have a definition of ASTContext around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159718 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-03[analyzer] For now, don't inline non-static member overloaded operators.Jordan Rose
Our current inlining support (specifically RegionStore::enterStackFrame) doesn't know that calls to overloaded operators may be calls to non-static member functions, and that in these cases the first argument should be treated as 'this'. This caused incorrect results and sometimes crashes. The long-term fix will be to rewrite RegionStore::enterStackFrame to use CallEvent and its subclasses, but for now we can just disable these problematic calls by classifying them under a new CallEvent, CXXMemberOperatorCall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159692 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-03When using -pg targeting OS X 10.8, pass -no_new_main to the linker.Bob Wilson
By default on OS X 10.8, we don't link with a crt1.o file and the linker knows to use _main as the entry point. But, when compiling with -pg, we need to link with the gcrt1.o file, and the linker needs to be told to use the "start" symbol as the entry point. The -no_new_main linker option does that last part. <rdar://problem/11491405> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159683 91177308-0d34-0410-b5e6-96231b3b80d8
