From 677ef6230b603571ae05125db469f7b4c8912a77 Mon Sep 17 00:00:00 2001 From: KONRAD Frederic Date: Mon, 10 Aug 2015 17:27:02 +0200 Subject: replace spinlock by QemuMutex. spinlock is only used in two cases: * cpu-exec.c: to protect TranslationBlock * mem_helper.c: for lock helper in target-i386 (which seems broken). It's a pthread_mutex_t in user-mode, so we can use QemuMutex directly, with an #ifdef. The #ifdef will be removed when multithreaded TCG will need the mutex as well.
