search for: schedulingbarrier

I found myself wanting a "scheduling barrier" in LLVM. In my specific circumstances I only want it to mean that TargetInstrInfoImpl::isSchedulingBoundary() would return true. I added SchedulingBarrier to MCID in MCInstrDesc.h and pushed it through TD attributes down to isSchedulingBoundary(). Is this something of general interest, or is there another mechanism for implementing barriers that I missed? Thanks -------------- next part -------------- An HTML attachment was scrubbed...
