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

2013-03-14Avoid computing the linkage too early. Don't invalidate it.Rafael Espindola
Before this patch we would compute the linkage lazily and cache it. When the AST was modified in ways that could change the value, we would invalidate the cache. That was fairly brittle, since any code could ask for the a linkage before the correct value was available. We should change the API to one where the linkage is computed explicitly and trying to get it when it is not available asserts. This patch is a first step in that direction. We still compute the linkage lazily, but instead of invalidating a cache, we assert that the AST modifications didn't change the result. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176999 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-13Have these attriubtes set to 'true' or 'false'.Bill Wendling
The back-end cannot differentiate between functions that are from a .ll file and those generated from the front-end. We cannot then take the non-precense of these attributes as a "false" value. Have the front-end explicitly set the value to 'true' or 'false' depending upon what is actually set. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176985 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-13[Modules] Don't eagerly load and associate all the module header files.Argyrios Kyrtzidis
In a module-enabled Cocoa PCH file, we spend a lot of time stat'ing the headers in order to associate the FileEntries with their modules and support implicit module import. Use a more lazy scheme by enhancing HeaderInfoTable to store extra info about the module that a header belongs to, and associate it with its module only when there is a request for loading the header info for a particular file.

2013-03-13[Modules] Resolve top-headers of modules lazily.Argyrios Kyrtzidis
This allows resolving top-header filenames of modules to FileEntries when we need them, not eagerly.

2013-03-13[analyzer] BugReporter - more precise tracking of C++ referencesAnna Zaks
When BugReporter tracks C++ references involved in a null pointer violation, we want to differentiate between a null reference and a reference to a null pointer. In the first case, we want to track the region for the reference location; in the second, we want to track the null pointer. In addition, the core creates CXXTempObjectRegion to represent the location of the C++ reference, so teach FindLastStoreBRVisitor about it. This helps null pointer suppression to kick in. (Patch by Anna and Jordan.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176969 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-12Driver: -ccc-install-dir should affect cc1 -resource-dirJim Grosbach
-ccc-install-dir is supposed to cause the compiler to behave as-if it were installed in the indicated location. It almost does, but misses anything that's relying on the resource directory (libc++ header search, in particular). The resource dir is resolved too early, before command line args are handled. The fix is simply to move handling of the resource dir until after we know if a -ccc-install-dir is present. rdar://13402696 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176894 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-11[analyzer] Look for calls along with lvalue nodes in trackNullOrUndefValue.Jordan Rose
r176737 fixed bugreporter::trackNullOrUndefValue to find nodes for an lvalue even if the rvalue node had already been collected. This commit extends that to call statement nodes as well, so that if a call is contained within implicit casts we can still track the return value. No test case because node reclamation is extremely finicky (dependent on how the AST and CFG are built, and then on our current reclamation rules, and /then/ on how many nodes were generated by the analyzer core and the current set of checkers). I consider this a low-risk change, though, and it will only happen in cases of reclamation when the rvalue node isn't available. <rdar://problem/13340764> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176829 91177308-0d34-0410-b5e6-96231b3b80d8
