[Qemu-devel] correct TCG_CALL_* flags for helpers which directly access env fields? |

Hi; just wanted to check my understanding of how the
TCG_CALL_* flags work.
In particular, for the fairly common case of helpers which
read or write fields in the CPU state via being passed an
'env' pointer, what are the correct flags? Assuming the fields
it accesses aren't also being used for TCG memory globals,
presumably NO_RWG_SE if the field is only read, and
NO_RWG if it's written?
thanks
