2013-03-19<rdar://problem/13363214> Eliminate race condition between module rebuild ↵Douglas Gregor
and the global module index. The global module index was querying the file manager for each of the module files it knows about at load time, to prune out any out-of-date information. The file manager would then cache the results of the stat() falls used to find that module file. Later, the same translation unit could end up trying to import one of the module files that had previously been ignored by the module cache, but after some other Clang instance rebuilt the module file to bring it up-to-date. The stale stat() results in the file manager would trigger a second rebuild of the already-up-to-date module, causing failures down the line. The global module index now lazily resolves its module file references to actual AST reader module files only after the module file has been loaded, eliminating the stat-caching race. Moreover, the AST reader can communicate to its caller that a module file is missing (rather than simply being out-of-date), allowing us to simplify the module-loading logic and allowing the compiler to recover if a dependent module file ends up getting deleted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177367 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-16[analyzer] Model trivial copy/move assignment operators with a bind as well.Jordan Rose
r175234 allowed the analyzer to model trivial copy/move constructors as an aggregate bind. This commit extends that to trivial assignment operators as well. Like the last commit, one of the motivating factors here is not warning when the right-hand object is partially-initialized, which can have legitimate uses. <rdar://problem/13405162> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177220 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-16Exploit this-return of a callsite in a this-return function.Manman Ren
For constructors/desctructors that return 'this', if there exists a callsite that returns 'this' and is immediately before the return instruction, make sure we are using the return value from the callsite. We don't need to keep 'this' alive through the callsite. It also enables optimizations in the backend, such as tail call optimization. rdar://12818789 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177211 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-15Improve template diffing handling of default integer values.Richard Trieu
When the template argument is both default and value dependent, the expression retrieved for the default argument cannot be evaluated, thus never matching any argument value. To get the proper value, get the template argument from the desugared template specialization. Also, output the original expression to provide more information about the argument mismatch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177209 91177308-0d34-0410-b5e6-96231b3b80d8

Fixes a FIXME, improves dead symbol collection, suppresses a false positive, which resulted from reusing the same symbol twice for simulation of 2 calls to the same function. Fixing this lead to 2 possible false negatives in CString checker. Since the checker is still alpha and the solution will not require revert of this commit, move the tests to a FIXME section. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177206 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-14Flag that friend function definitions are "late parsed" so thatJohn McCall
template instantiation will still consider them to be definitions if we instantiate the containing class before we get around to parsing the friend. This seems like a legitimate use of "late template parsed" to me, but I'd appreciate it if someone responsible for the MS feature would look over this. This file already appears to access AST nodes directly, which is arguably not kosher in the parser, but the performance of this path matters enough that perpetuating the sin is justifiable. Probably we ought to reconsider this policy for very simple manipulations like this. The reason this entire thing is necessary is that function template instantiation plays some very gross games in order to not associate an instantiated function template with the class it came from unless it's a definition, and the reason *that's* necessary is that the AST currently cannot represent the instantiation history of individual function template declarations, but instead tracks it in common for the entire function template. That probably prevents us from correctly reporting ill-formed calls to ambiguously instantiated friend function templates. rdar://12350696 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177003 91177308-0d34-0410-b5e6-96231b3b80d8
