From 5bd37b8e78980beed2861bbdc7f8f28fc3f72671 Mon Sep 17 00:00:00 2001 From: Joel Sing Date: Mon, 9 May 2016 02:13:03 +1000 Subject: [PATCH] runtime: stop using sigreturn on openbsd/386 In future releases of OpenBSD, the sigreturn syscall will no longer exist. As such, stop using sigreturn on openbsd/386 and just return from the signal trampoline (as we already do for openbsd/amd64 and openbsd/arm).
