This attribute applies to declarations of C stdlib functions (sprintf, memcpy...) that have known fortified variants (__sprintf_chk, __memcpy_chk, ...). When applied, clang will emit calls to the fortified variant functions instead of calls to the defaults. In GCC, this is done by adding gnu_inline-style wrapper functions, but that doesn't work for us for variadic functions because we don't support __builtin_va_arg_pack (and have no intention to). This attribute takes two arguments, the first is 'type' argument passed through to __builtin_object_size, and the second is a flag argument that gets passed through to the variadic checking variants. rdar://47905754 Differential revision: https://reviews.llvm.org/D57918 llvm-svn: 353765 |

//===----------------------------------------------------------------------===// // 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.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
