2009-09-27Fix:Ted Kremenek
<rdar://problem/6914474> checker doesn't realize that variable might have been assigned if a pointer to that variable was passed to another function via a structure The problem here was the RegionStoreManager::InvalidateRegion didn't invalidate the bindings of invalidated regions. This required a rewrite of this method using a worklist. As part of this fix, changed ValueManager::getConjuredSymbolVal() to require a 'void*' SymbolTag argument. This tag is used to differentiate two different symbols created at the same location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82920 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-26Rework the Parse-Sema interaction for friends to better support friendDouglas Gregor
class templates. We now treat friend class templates much more like normal class templates, except that they still get special name lookup rules.

2009-09-25Declarators can now properly represent template-ids, e.g., forDouglas Gregor
template void f<int>(int); ~~~~~~ Previously, we silently dropped the template arguments. With this change, we now use the template arguments (when available) as the explicitly-specified template arguments used to aid template argument deduction for explicit template instantiations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82806 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-25WIP implementation of explicit instantiation of function templates,Douglas Gregor
member functions of class template specializations, and static data members. The mechanics are (mostly) present, but the semantic analysis is very weak. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82789 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-24WIP implementation of explicit function template specialization. ThisDouglas Gregor
first implementation recognizes when a function declaration is an explicit function template specialization (based on the presence of a template<> header), performs template argument deduction + ambiguity resolution to determine which template is being specialized, and hooks There are many caveats here: - We completely and totally drop any explicitly-specified template arguments on the floor - We don't diagnose any of the extra semantic things that we should diagnose. - I haven't looked to see that we're getting the right linkage for explicit specializations On a happy note, this silences a bunch of errors that show up in libstdc++'s <iostream>, although Clang still can't get through the entire header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82728 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-24Refactor the representation of qualifiers to bring ExtQualType out of theJohn McCall
Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our use of qualifiers and fix a few places that weren't dealing with qualifiers quite right; many more remain. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82705 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-24When building CFGs, no longer reverse the statements in the CFGBlock. InsteadTed Kremenek
have the iterators and operator[] handle the traversal of statements, as they are stored in reverse order. Tests show this has no real performance impact, but it does simply the CFG construction logic and will make it slightly easier to change the allocation strategy for CFGBlocks (as we have fewer copies). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82702 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-23This patch addresses a few issues related to 8.5.3 [dcl.init.ref]Fariborz Jahanian
It uses a recent API to find inherited conversion functions to do the initializer to reference lvalue conversion (and removes a FIXME). It issues the ambiguity diagnostics when multiple conversions are found. WIP. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82649 91177308-0d34-0410-b5e6-96231b3b80d8

the start of a nested-name-specifier, add the "::" after the nested-name-specifier to the code-completion string. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82587 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-22Tweak the code-completion results ranking and formation, so thatDouglas Gregor
members found in base classes have the same ranking as members found in derived classes. However, we will introduce an informative note for members found in base classes, showing (as a nested-name-specifier) the qualification to name the base class, to make it clear which members are from bases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82586 91177308-0d34-0410-b5e6-96231b3b80d8

Parse it in both C and C++, but diagnose it as an error in C with a fix-it hint to add the comma. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82576 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-22Replace the -code-completion-dump option with Douglas Gregor
-code-completion-at=filename:line:column which performs code completion at the specified location by truncating the file at that position and enabling code completion. This approach makes it possible to run multiple tests from a single test file, and gives a more natural command-line interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82571 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-22Implement code completion within a function call, triggered after theDouglas Gregor
opening parentheses and after each comma. We gather the set of visible overloaded functions, perform "partial" overloading based on the set of arguments that we have thus far, and return the still-viable results sorted by the likelihood that they will be the best candidate. Most of the changes in this patch are a refactoring of the overloading routines for a function call, since we needed to separate out the notion of building an overload set (common to code-completion and normal semantic analysis) and then what to do with that overload set. As part of this change, I've pushed explicit template arguments into a few more subroutines. There is still much more work to do in this area. Function templates won't be handled well (unless we happen to deduce all of the template arguments before we hit the completion point), nor will overloaded function-call operators or calls to member functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82549 91177308-0d34-0410-b5e6-96231b3b80d8
