Douglas Gregor ad2c6988a2 Introduce new AST statistics that keep track of the number of isa (or ... 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). llvm-svn: 99912		2010-03-30 18:56:13 +00:00
