From 1de14d77bbd1237ec03779b8a2e757f52978bbd9 Mon Sep 17 00:00:00 2001 From: Kamil Rytarowski Date: Mon, 20 Jul 2020 17:07:25 +0200 Subject: [PATCH] Enable multi-process mode in the NetBSD native target. This enables proper support for multiple inferiors and ptrace(2) assisted management of the inferior processes and their threads.
