[Qemu-devel] [PATCH v6 15/35] tcg: Add CONFIG_ATOMIC64

2016-10-11 Thread Richard Henderson

Allow qemu to build on 32-bit hosts without 64-bit atomic ops. Even if we only allow 32-bit hosts to multi-thread emulate 32-bit guests, we still need some way to handle the 32-bit guest using a 64-bit atomic operation. Do so by dropping back to single-step. Signed-off-by: Richard Henderson
