I want to know the cost(throughput & latency) of MPX instructions(e.g. BNDCU , BNDCL, and so on). But I can't find it in Intel's optimization manual. Is there any information about it?
This is not related to SGX question. Please refer this link https://software.intel.com/en-us/forums/intel-isa-extensions
For more complete information about compiler optimizations, see our Optimization Notice.
