From 363636787d49a46840d415c2dbc925d287ed0206 Mon Sep 17 00:00:00 2001 From: Ani Sinha Date: Tue, 3 Oct 2023 15:58:02 +0530 Subject: [PATCH] hw/i386: changes towards enabling -Wshadow=local for x86 machines MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Code changes that addresses all compiler complaints coming from enabling -Wshadow flags. Enabling -Wshadow catches cases of local variables shadowing other local variables or parameters. These makes the code confusing and/or adds bugs that are difficult to catch.
