From: Zachary T Welch Date: Mon, 16 Nov 2009 11:29:30 +0000 (-0800) Subject: move ARRAY_SIZE macro to types.h X-Git-Tag: v0.4.0-rc1~566 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=dc1685ca25567fe75c8d50c825fb0303fbb66fac;p=openocd move ARRAY_SIZE macro to types.h The ARRAY_SIZE macro was defined in several target files, so move it to types.h. This patch also removes two other identical macros: DIM (from jtag.h) and asizeof (from arm11.h). --- diff --git a/src/helper/types.h b/src/helper/types.h index 8f6283b5..96a923b8 100644 --- a/src/helper/types.h +++ b/src/helper/types.h @@ -60,6 +60,16 @@ typedef bool _Bool;
