[Qemu-devel] [PATCH 02/11] target-arm: Extend NZCF to 64 bits

2015-02-19 Thread Richard Henderson
The resulting aarch64 translation is a bit cleaner. Sign-extending from 32-bits is simpler than having to use setcond to narrow from 64-bits. Signed-off-by: Richard Henderson --- target-arm/cpu.h | 21 ++-- target-arm/helper.c| 18 ++- target-arm/translate-a64.c | 297 +++
