Subject: [Qemu-devel] [PATCH] Fix breakpoints in nios2 user-mode emulation.
Date: Tue, 11 Sep 2018 14:29:39 -0700	[thread overview]
Message-ID: <1536701379-106032-1-git-send-email-sandra@codesourcery.com> (raw)

Without this patch, QEMU exits immediately when it execution stops at
a breakpoint, instead of reporting it to GDB.
