Duncan P. N. Exon Smith 96a01fa046 Lex: Never overflow the file in HeaderMap::lookupFilename() If a header map file is corrupt, the strings in the string table may not be null-terminated. The logic here previously relied on `MemoryBuffer` always being null-terminated, but this isn't actually guaranteed by the class AFAICT. Moreover, we're seeing a lot of crash traces at calls to `strlen()` inside of `lookupFilename()`, so something is going wrong there. Instead, use `strnlen()` to get the length, and check for corruption. Also remove code paths that could call `StringRef(nullptr)`. r261459 made these rather obvious (although they'd been there all along). llvm-svn: 261461		2016-02-21 00:14:36 +00:00

// 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:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
