From 857b55adb77004d9ec9202078b7f1f3a1a076112 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 7 Sep 2015 10:39:27 +0100 Subject: [PATCH] target-arm/arm-semi.c: Fix broken SYS_WRITE0 via gdb A spurious trailing "\n" in the gdb syscall format string used for SYS_WRITE0 meant that gdb would reject the remote syscall, with the effect that the output from the guest was silently dropped. Remove the newline so that gdb accepts the packet.
