I'm starting to wonder if IWYU is worth the effort. Nonetheless, this
makes it lint clean on macOS and reduces the number of warnings on
FreeBSD and Linux.
Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.
Fixes#2957
In keeping with the change made by @ridiculousfish earlier today modify
the `keyword_description()` function to return a const wchar_t pointer.
Also, simplify the `token_type_description()` function to use the recently
introduced mapping array. This changes the wording of many of the token
type descriptions. However, I can't see this as being a problem since
the original descriptions (e.g., "token_redirection") are no clearer to
someone not acquainted with the implementation.
Introduces a new template moved_ref which is like an rvalue reference.
This allows passing around objects while being explicit that the
receiver may acquire ownership. This will help reduce some allocations.
Rather than returning a list of productions and an index,
return the relevant production directly from the rule function.
Also introduce a tag value (replacing production_idx) which tracks
information like command decorations, etc. with more clarity.
This change moves source files into a src/ directory,
and puts object files into an obj/ directory. The Makefile
and xcode project are updated accordingly.
Fixes#1866
