From 9df62f054406992ce41ec4558fca6a0fa56fffeb Mon Sep 17 00:00:00 2001 From: Chen Gang <gang.chen.5i5j@gmail.com> Date: Sun, 12 Jan 2014 09:59:13 +0800 Subject: arch: use ASM_NL instead of ';' for assembler new line character in the macro For some assemblers, they use another character as newline in a macro (e.g. arc uses '`'), so for generic assembly code, need use ASM_NL (a macro) instead of ';' for it.
