Subject: [PATCH 31/40] sim/ppc: Initialize help variables
Date: Thu, 20 Oct 2022 09:32:36 +0000 [thread overview]
Message-ID: <91681f1c5c0144e59196ec40e456f214cc74568d.1666258361.git.research_trasio@irq.a4lg.com> (raw)
In-Reply-To: <cover.1666258361.git.research_trasio@irq.a4lg.com>
GCC / Clang generate a warning if a variables is used uninitialized on some
cases. On the default configuration, it causes a build failure (unless
"--disable-werror" is specified).
This commit initializes two help variables with { 0 }.
