From 907bff917a659a8e50e285dc42ef51d7eaba6e62 Mon Sep 17 00:00:00 2001 From: Yaowei Bai Date: Tue, 29 Sep 2015 22:43:35 +0800 Subject: [PATCH] tracing: is_legal_op() can return boolean Make is_legal_op() return bool to improve readability due to this particular function only using either one or zero as its return value. No functional change.
