2013-05-05Make all 'is in extern "C"' tests use the lexical context.Rafael Espindola
I was not able to find a case (other than the fix in r181163) where this makes a difference, but it is a more obviously correct API to have. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181165 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-03Correctly emit certain implicit references to 'self' even withinJohn McCall
a lambda. Bug #1 is that CGF's CurFuncDecl was "stuck" at lambda invocation functions. Fix that by generally improving getNonClosureContext to look through lambdas and captured statements but only report code contexts, which is generally what's wanted. Audit uses of CurFuncDecl and getNonClosureAncestor for correctness. Bug #2 is that lambdas weren't specially mapping 'self' when inside an ObjC method. Fix that by removing the requirement for that and using the normal EmitDeclRefLValue path in LoadObjCSelf. rdar://13800041 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181000 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-08<rdar://problem/12806802> Propagate access specifiers for conversion ↵Douglas Gregor
functions to the conversion function set eagerly. This slightly propagates an existing hack that delays when we provide access specifiers for the visible conversion functions of a class by copying the available access specifier early. The only client this affects is LLDB, which tends to discover and add conversion functions after the class is technically "complete". As such, the only observable difference is in LLDB, so the testing will go there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179029 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-03Pare back r164351 somewhat. The problem that change was addressing was that weRichard Smith
don't serialize a lookup map for the translation unit outside C++ mode, so we can't tell when lookup within the TU needs to look within modules.

2013-02-14Add a getLanguageLinkage method to VarDecls and FunctionDecls. Use it to fixRafael Espindola
some cases where functions with no language linkage were being treated as having C language linkage. In particular, don't warn in extern "C" { static NonPod foo(); } Since getLanguageLinkage checks the language linkage, the linkage computation cannot use the language linkage. Break the loop by checking just the context in the linkage computation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175117 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-12Remove an assert which triggers when a decl context in a module hits the 'hasRichard Smith

2013-02-09Ensure that type definitions present in just-loaded modules areDouglas Gregor
visible. The basic problem here is that a given translation unit can use forward declarations to form pointers to a given type, say, class X; X *x; and then import a module that includes a definition of X: import XDef; We will then fail when attempting to access a member of X, e.g., x->method() because the AST reader did not know to look for a default of a class named X within the new module. This implementation is a bit of a C-centric hack, because the only definitions that can have this property are enums, structs, unions, Objective-C classes, and Objective-C protocols, and all of those are either visible at the top-level or can't be defined later. Hence, we can use the out-of-date-ness of the name and the identifier-update mechanism to force the update. In C++, we will not be so lucky, and will need a more advanced solution, because the definitions could be in namespaces defined in two different modules, e.g., // module 1 namespace N { struct X; } // module 2 namespace N { struct X { /* ... */ }; } One possible implementation here is for C++ to extend the information associated with each identifier table to include the declaration IDs of any definitions associated with that name, regardless of context. We would have to eagerly load those definitions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174794 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-07Fix handling of module imports adding names to a DeclContext after qualifiedRichard Smith
name lookup has been performed in that context (this probably only happens in C++). 1) Whenever we add names to a context, set a flag on it, and if we perform lookup and discover that the context has had a lookup table built but has the flag set, update all entries in the lookup table with additional names from the external source. 2) When marking a DeclContext as having external visible decls, mark the context in which lookup is performed, not the one we are adding. These won't be the same if we're adding another copy of a pre-existing namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174577 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-12Disable caching of visibility.Rafael Espindola
The testcase in pr14929 shows that this is extremely hard to do. If we choose to apply the attribute, that causes the visibility of some decls to change and that can happen really late (during codegen). Current gcc warns and ignores the attribute in this testcase with a warning. This suggest that the correct solution is to find a point in the compilation where we can compute the visibility and * assert it was never computed before * reject any attempts to compute it again in the future (with warnings). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172305 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-01Remove ref/value inconsistency in redecl_iterator.David Blaikie
Similar to r155808 - this mistake has been made in a few iterators. Based on Chandler Carruth's feedback to r155808 I added an implicit conversion to Decl* to ease adoption/usage. Useful for the pointer comparison, but not the dyn_cast (due to template argument deduction causing the conversion not to be used) - there for future convenience, though. This idiom (op T* for iterators) seems to be fairly idiomatic within the LLVM codebase & I'll likely add it as I fix up the other iterators here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155869 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-16Fix Objective-C compilation-time performance regression introduced in r152608.Richard Smith
Reintroduce lazy name lookup table building, ensuring that the lazy building step produces the same lookup table that would be built by the eager step. Avoid building a lookup table for the translation unit outside C++, even in cases where we can't recover the contents of the table from the declaration chain on the translation unit, since we're not going to perform qualified lookup into it anyway. Continue to support lazily building such lookup tables for now, though, since ASTMerge uses them. In my tests, this performs very similarly to ToT with r152608 backed out, for C, Obj-C and C++, and does not suffer from PR10447. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152905 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
