From 54d5123a56011f805500a8d18e178874300be1f7 Mon Sep 17 00:00:00 2001 From: Cody P Schafer Date: Sun, 27 Jul 2014 22:28:53 -0400 Subject: [PATCH] configurator: add BUILTIN_CTZ*, BUILTIN_FFS, and ICCARM_INTRINSICS Realistically, the ICCARM_INTRINSICS probably won't ever be generated by configurator, but will show up in manually created or alternately generated config.h's.
