2010-03-31For reverse data flow analyses, enqueue the blocks in reverse order.Ted Kremenek
This more likely matches with the ideal order the blocks should be visited. This shaves another 1% off the -fsyntax-only time for compare.c (403.gcc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100030 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-31Tweak DataFlowSolver's worklist data structure to have an ordered worklistTed Kremenek
and a DenseSet for caching instead of using a single SmallPtrSet. This makes the behavior of the DataFlowSolver more deterministic, and reduces the -fsyntax-only time on compare.c (403.gcc) by 1%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100026 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-31Rename CodeModificationHint to FixItHint, since we've been using theDouglas Gregor

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
2010-03-30Add a test for C++ [stmt.select]p3, which specifies that redeclaring aDouglas Gregor
name in the outermost block of a if/else that declares the same name is ill-formed. Turns out that Clang and MSVC were right about PR6739; GCC is too lax. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99937 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

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.

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
