From 4cf41e80848bdca274b350b878881e2fa809ea0a Mon Sep 17 00:00:00 2001 From: Doug Rabson Date: Sat, 10 Dec 2022 08:38:04 +0000 Subject: [PATCH] bsd-user: Don't truncate the return value from freebsd_syscall System call return values on FreeBSD are in a register (which is spelled abi_long in qemu). This was being assigned into an int variable which causes problems for 64bit targets.
