2010-03-31use the new optimized debug info metadata accessors. InChris Lattner
addition to the inherent win, this eliminates the pointless cost of going through the name -> mdkind stringmap that we were paying. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99983 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-31IRGen: Move the auxiliary data structures tracking AST -> LLVM mappings out ↵Daniel Dunbar
of CodeGenTypes, to per-record CGRecordLayout structures. - I did a cursory check that this was perf neutral, FWIW. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99978 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-31Drastically simplify the computation of linkage for typeinfo by usingDouglas Gregor
the existing (and already well-tested) linkage computation for types, with minor tweaks for dynamic classes and (pointers to) incomplete types. Fixes PR6597. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99968 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30When "delayed parsing" C++ default arguments, if there is an error, there ↵Argyrios Kyrtzidis
may be tokens left in the token stream that will interfere (they will be parsed as if they are after the class' '}') and a crash will occur because the CachedTokens that holds them will be deleted while the lexer is still using them. Make sure that the tokens of default args are removed from the token stream. Fixes PR6647. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99939 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Propagate the "found declaration" (i.e. the using declaration instead ofJohn McCall
the underlying/instantiated decl) through a lot of API, including "intermediate" MemberExprs required for (e.g.) template instantiation. This is necessary because of the access semantics of member accesses to using declarations: only the base class *containing the using decl* need be accessible from the naming class. This allows us to complete an access-controlled selfhost, if there are no recent regressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99936 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30Improve diagnostics when printing a template instantiation backtraceDouglas Gregor
involving substitution of deduced template arguments into a class template partial specialization or function template, or when substituting explicitly-specific template arguments into a function template. We now print the actual deduced argument bindings so the user can see what got deduced. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99923 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30the big refactoring bits of PR3782.Rafael Espindola
This introduces FunctionType::ExtInfo to hold the calling convention and the noreturn attribute. The next patch will extend it to include the regparm attribute and fix the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99920 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Introduce new AST statistics that keep track of the number of isa (orDouglas Gregor
dyn_cast) invocations for C++ and Objective-C types, declarations, expressions, and statements. The statistics will be printed when -print-stats is provided to Clang -cc1, with results such as: 277073 clang - Number of checks for C++ declaration nodes 13311 clang - Number of checks for C++ expression nodes 18 clang - Number of checks for C++ statement nodes 174182 clang - Number of checks for C++ type nodes 92300 clang - Number of checks for Objective-C declaration nodes 9800 clang - Number of checks for Objective-C expression nodes 7 clang - Number of checks for Objective-C statement nodes 65733 clang - Number of checks for Objective-C type nodes The statistics are only gathered when NDEBUG is not defined, since they introduce potentially-expensive operations into very low-level routines (isa). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99912 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-29When copying a partial diagnostic into a DependentDiagnostic, allocateDouglas Gregor
storage for that partial diagnostic via the ASTContext's BumpPtrAllocator rather than using up slots in the ASTContext's cache. Now that we do this, we don't have to worry about destroying dependent diagnostics when destroying a DependentStoredDeclsMap. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99854 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29Optimize PartialDiagnostic's memory-allocation behavior by placing aDouglas Gregor
cache of PartialDiagnostic::Storage objects into an allocator within the ASTContext. This eliminates a significant amount of malloc traffic, for a 10% performance improvement in -fsyntax-only wall-clock time with 403.gcc's combine.c. Also, eliminate the RequireNonAbstractType hack I put in earlier, which was but a symptom of this larger problem. Fixes <rdar://problem/7806091>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99849 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-29When collecting virtual bases it's very important to use the canonical type ↵Anders Carlsson
of the base class. Otherwise, we might add the same virtual base class twice if the virtual base is an instantiated template. Fixes PR6251. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99829 91177308-0d34-0410-b5e6-96231b3b80d8
