2013-03-14Don't try to typo-correct 'super' in an objc method.Argyrios Kyrtzidis
This created 2 issues: 1) Performance issue, since typo-correction with PCH/modules is rather expensive. 2) Correctness issue, since if it managed to "correct" 'super' then bogus compiler errors would be emitted, like this: 3.m:8:3: error: unknown type name 'super'; did you mean 'super1'? super.x = 0; ^~~~~ super1 t3.m:5:13: note: 'super1' declared here typedef int super1; ^ t3.m:8:8: error: expected identifier or '(' super.x = 0; ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177126 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-14[analyzer] Change the way in which IDC Visitor decides to kick in and make ↵Anna Zaks
sure it attaches in the given edge case In the test case below, the value V is not constrained to 0 in ErrorNode but it is in node N. So we used to fail to register the Suppression visitor. We also need to change the way we determine that the Visitor should kick in because the node N belongs to the ExplodedGraph and might not be on the BugReporter path that the visitor sees. Instead of trying to match the node, turn on the visitor when we see the last node in which the symbol is ‘0’. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177121 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

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[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.
