[Qemu-devel] [PATCH 04/10] target-s390x: fix setcc in TCG mode

[Aurelien Jarno]

In TCG mode we should store the CC value in env->cc_op. However do it
inconditionnaly because:
- the tcg_enabled function is not inlined
- it's probably faster to always store the value, especially given it
  is likely in the same cache line than env->psw.mask.
