Subject: [PATCH 4/4] target/avr: fix interrupt processing
Date: Sat, 19 Nov 2022 08:56:10 +0300 [thread overview]
Message-ID: <166883737070.1540909.16280727343064648296.stgit@pasha-ThinkPad-X280> (raw)
In-Reply-To: <166883734868.1540909.6779276759642478650.stgit@pasha-ThinkPad-X280>
Interrupt bit vector has 64 bits, but interrupt vector is found with ctz32
function. This patch replaces it with ctz64.
