[PATCH 08/19] target/ppc: Clear fpstatus flags on VSX_CVT_INT_TO_FP_VECT


From: Víctor Colombo
Subject: [PATCH 08/19] target/ppc: Clear fpstatus flags on VSX_CVT_INT_TO_FP_VECTOR
Date: Thu, 1 Sep 2022 10:17:45 -0300

Fix xscvsdqp incorrectly not clearing the FI bit.
Power ISA states that xscvsdqp should always set FPSCR.FI=0
Right now, QEMU sometimes is incorrectly setting the flag to 1.
