2012-03-27[preprocessor] Handle correctly inclusion directives that have macro ↵Argyrios Kyrtzidis
expansions, e.g "#include MACRO(STUFF)". -As an inclusion position for the included file, use the file location of the file where it was included but *after* the macro expansions. We want the macro expansions to be considered as before-in-translation-unit for everything in the included file. -In the preprocessing record take into account that only inclusion directives can be encountered as "out-of-order" (by comparing the start of the range which for inclusions is the hash location) and use binary search if there is an extreme number of macro expansions in the include directive.

2012-03-27Change RetainCountChecker to eagerly "escape" retained objects when they areTed Kremenek
assigned to a struct. This is fallout from inlining results, which expose far more patterns where people stuff CF objects into structs and pass them around (and we can reason about it). The problem is that we don't have a general way to detect when values have escaped, so as an intermediate step we need to eagerly prune out such tracking. Fixes <rdar://problem/11104566>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153489 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-27When we see 'Class(X' or 'Class::Class(X' and we suspect that it names aRichard Smith
constructor, but X is not a known typename, check whether the tokens could possibly match the syntax of a declarator before concluding that it isn't a constructor. If it's definitely ill-formed, assume it is a constructor. Empirical evidence suggests that this pattern is much more often a constructor with a typoed (or not-yet-declared) type name than any of the other possibilities, so the extra cost of the check is not expected to be problematic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153488 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-26Add a special-case diagnostic for one of the more obnoxious special cases ofRichard Smith
unscoped enumeration members: an enumerator name which is visible in the out-of-class definition of a member of a templated class might not actually exist in the instantiation of that class, if the enumeration is also lexically defined outside the class definition and is explicitly specialized. Depending on the result of a CWG discussion, we may have a different resolution for a class of problems in this area, but this fixes the immediate issue of a crash-on-invalid / accepts-invalid (depending on +Asserts). Thanks to Johannes Schaub for digging into the standard wording to find how this case is currently specified to behave. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153461 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-26Driver: Factor string vector push_back into a helper class and optimize it.Benjamin Kramer
Due to lack of move semantics we would create a temporary std::string from the string literal, copy it into the vector and discard the temporary. This leads to massive code bloat, optimizing it saves 50k on i386-linux-Release+Asserts. While there add a two-element overload for push_back, simplifying code a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153441 91177308-0d34-0410-b5e6-96231b3b80d8
