2012-03-28Unify and fix our checking of C++ [dcl.meaning]p1's requirementsDouglas Gregor
concerning qualified declarator-ids. We now diagnose extraneous qualification at namespace scope (which we had previously missed) and diagnose these qualification errors for all kinds of declarations; it was rather uneven before. Fixes <rdar://problem/11135644>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153577 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-28When we form a new function/class template specialization, we firstDouglas Gregor
search for the specialization (in a folding set) and, if not found form a *Decl that is then inserted into that folding set. In rare cases, the folding set may be reallocated between the search and the insertion, causing a crash. No test case, because triggering rehashing consistently in a small test case is not feasible. Fixes <rdar://problem/11115071>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153575 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-27Introduce a new libclang API to determine the parent context of a codeDouglas Gregor
completion item. For example, if the code completion itself represents a declaration in a namespace (say, std::vector), then this API retrieves the cursor kind and name of the namespace (std).

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

2012-03-18Use character literals for vexing initialization fixit hints.David Blaikie
Instead of suggesting " = 0" for "char c();", suggest " = '\0'", and similarly for other char types (wide, 16, and 32). Add tests for all these, and since this means testing such hints under C++0x, add tests for some untested C++0x hint cases in the existing code, including suggesting nullptr for pointer initialization. This sets up the initialization helper to provide better type fidelity that will be especially helpful for non-assignment cases (such as fixit-correcting NULL usage in function calls (eg: foo(char) + foo(NULL) => foo('\0') instead of the less informative foo(0))) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153008 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-16Suppress macro expansion of NULL in NULL warnings.David Blaikie
For "int i = NULL;" we would produce: null.cpp:5:11: warning: implicit conversion of NULL constant to integer [-Wconversion] int i = NULL; ~ ^~~~ null.cpp:1:14: note: expanded from macro 'NULL' \#define NULL __null ^~~~~~ But we really shouldn't trace that macro expansion back into the header, yet we still want macro back traces for code like this: \#define FOO NULL int i = FOO; or \#define FOO int i = NULL; FOO While providing appropriate tagging at different levels of the expansion, etc. The included test case exercises these cases & does some basic validation (to ensure we don't have macro expansion notes where we shouldn't, and do where we should) - but doesn't go as far as to validate the source location/ranges used in those notes and warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152940 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-13Fix PR10447: lazily building name lookup tables for DeclContexts was broken.Richard Smith
The deferred lookup table building step couldn't accurately tell which Decls should be included in the lookup table, and consequently built different tables in some cases. Fix this by removing lazy building of DeclContext name lookup tables. In practice, the laziness was frequently not worthwhile in C++, because we performed lookup into most DeclContexts. In C, it had a bit more value, since there is no qualified lookup. In the place of lazy lookup table building, we simply don't build lookup tables for function DeclContexts at all. Such name lookup tables are not useful, since they don't capture the scoping information required to correctly perform name lookup in a function scope. The resulting performance delta is within the noise on my testing, but appears to be a very slight win for C++ and a very slight loss for C. The C performance can probably be recovered (if it is a measurable problem) by avoiding building the lookup table for the translation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152608 91177308-0d34-0410-b5e6-96231b3b80d8
