Subject: [PATCH for-7.2] accel/tcg: Suppress compiler warning with flag -Wclobbered
Date: Sat,  5 Nov 2022 12:44:24 +0100	[thread overview]
Message-ID: <20221105114424.622563-1-sw@weilnetz.de> (raw)

At least some versions of gcc show a warning when compiler flag -Wclobbered
is used (tested with gcc on Debian bookworm i386 and with cross gcc for
Windows on Debian bullseye).
