This check is also accessible through the debug.ExprInspection checker. Like clang_analyzer_eval, you can use it to test the analyzer engine's current state; the argument should be true or false to indicate whether or not you expect the function to be inlined. When used in the positive case (clang_analyzer_checkInlined(true)), the analyzer prints the message "TRUE" if the function is ever inlined. However, clang_analyzer_checkInlined(false) should never print a message; this asserts that there should be no paths on which the current function is inlined, but then there are no paths on which to print a message! (If the assertion is violated, the message "FALSE" will be printed.) This asymmetry comes from the fact that the only other chance to print a message is when the function is analyzed as a top-level function. However, when we do that, we can't be sure it isn't also inlined elsewhere (such as in a recursive function, or if we want to analyze in both general or specialized cases). Rather than have all checkInlined calls have an appended, meaningless "FALSE" or "TOP-LEVEL" case, there is just no message printed. void clang_analyzer_checkInlined(int); For debugging purposes only! llvm-svn: 161708 |

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
