wyu 0.7 compatible with llvm+clang 3.9 is released. Major changes:
Add preliminary mappings for libc++.
Require the complete type for pointer arithmetic.
Recognize nested classes in friend declarations.
Better handling of X-macros/textual includes.
Better handling of self-checking private headers (that raise an #error if included directly).
Improve IWYU's understanding of implicit include dirs; the current source file's dirname is always a candidate now.
Add implicit include dirs for libc++ on Darwin targets.
Lots of internal cleanup based on output from clang-tidy.
Reduce logging strategically, to get more relevant output.
"Include what you use" means this: for every symbol (type, function
variable, or macro) that you use in foo.cc, either foo.cc or foo.h
should #include a .h file that exports the declaration of that symbol.
The include-what-you-use tool is a program that can be built with the
clang libraries in order to analyze #includes of source files to find
include-what-you-use violations, and suggest fixes for them.
The main goal of include-what-you-use is to remove superfluous #includes.
It does this both by figuring out what #includes are not actually needed for
this file (for both .cc and .h files), and replacing #includes with
forward-declares when possible.
