2012-05-09[AST/libclang] Speed up clang_getOverriddenCursors() considerably by ↵Argyrios Kyrtzidis
reserving a bit in ObjCMethodDecl to indicate whether the method does not override any other method, which is the majority of cases. That way we can avoid unnecessary work doing lookups, especially when PCH is involved. rdar://11360082 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156476 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-04Move Sema::RequireCompleteType() and Sema::RequireCompleteExprType()Douglas Gregor
off PartialDiagnostic. PartialDiagnostic is rather heavyweight for something that is in the critical path and is rarely used. So, switch over to an abstract-class-based callback mechanism that delays most of the work until a diagnostic is actually produced. Good for ~11k code size reduction in the compiler and 1% speedup in -fsyntax-only on the code in <rdar://problem/11004361>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156176 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-30Remove the ref/value inconsistency in filter_decl_iterator.David Blaikie
filter_decl_iterator had a weird mismatch where both op* and op-> returned T* making it difficult to generalize this filtering behavior into a reusable library of any kind. This change errs on the side of value, making op-> return T* and op* return T&. (reviewed by Richard Smith) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155808 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
