From 2d601b98643dd2846e2958d931826e7b7af44969 Mon Sep 17 00:00:00 2001 From: liqiong Date: Thu, 12 May 2022 22:32:30 +0800 Subject: tracing: Change "char *" string form to "char []" The "char []" string form declares a single variable. It is better than "char *" which creates two variables in the final assembly.
