◆ scheduleWriteOperands()

void gem5::VectorRegisterFile::scheduleWriteOperands ( Wavefront w,
GPUDynInstPtr  ii 
)
overridevirtual

if the instruction is a load with EXEC = 0, then we do not mark the reg. We do this to avoid a deadlock that can occur because a load reserves its destination regs before checking its exec mask, and in the cas it is 0, it will not send/recv any packets, and therefore it will never free its dst reg(s)
