Currently, the lexer returns T_ASSIGN for all of =, :=, and += associating yylval with the flavor. I want to make the generated lexer as simple as possible. So, the lexer should convert keywords to tokens without thinking about the meaning. = -> T_EQUAL := -> T_COLON_EQUAL += -> T_PLUS_EQUAL Unfortunately, Kconfig uses = instead of == for the equal operator. So, the same token T_EQUAL is used for assignment and comparison. The parser can still distinguish them from the context. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
