[PATCH 07/11] kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Linux commit 9a8dfb394c046742b2ac7444ba42272e11e9989d

Files suffixed by .lex.c, .tab.[ch] are generated lexers, parsers,
respectively.  Clean them up globally from the top Makefile.

Some of the final host programs those lexer/parser are linked into
are necessary for building external modules, but the intermediates
are unneeded.  They can be cleaned away by 'make clean' instead of
'make mrproper'.
