function AtomicSMImpl

simtix::AtomicSMImpl::AtomicSMImpl (
    const std::string & name,
    uint32_t cid,
    const ArchParam & p=kDefaultArchParam
)

function NotifyCtrlFlowChange

Notify the SM of a control flow change.

inline virtual void simtix::AtomicSMImpl::NotifyCtrlFlowChange (
    uint32_t wid,
    bool is_diverged,
    uint64_t wpc,
    uint64_t sswpc
) override

Parameters:

wid Warp ID.
is_diverged Whether the warp is diverged.
wpc Warp PC.
sswpc Spatial-subwarp PC.

This method should be called when a warp encounters a control flow change.
