From 7a88488bbc231e48a4a88ee2569bc0cc5d706f0a Mon Sep 17 00:00:00 2001 From: Roman Zippel Date: Tue, 8 Nov 2005 21:34:51 -0800 Subject: [PATCH] kconfig: use gperf for kconfig keywords Use gperf to generate a hash for the kconfig keywords. This greatly reduces the size of the generated scanner and makes it easier to extend kconfig.
