From 9c9d0acbe2793315fa6945a19685ad2a51fb281b Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Sun, 19 Jul 2020 17:10:49 -0600 Subject: dyndbg: prefer declarative init in caller, to memset in callee ddebug_exec_query declares an auto var, and passes it to ddebug_parse_query, which memsets it before using it. Drop that memset, instead initialize the variable in the caller; let the compiler decide how to do it.
