One problem about sgx enclave program running at Intel Core Processor (Haswell)

pp__monkeyking — Thu, 22 Apr 2021 11:05:44 GMT

I compile my sgx enclave program at Intel(R) Core(TM) i7-8665U CPU @ 1.90GHz by the cmd:

make SGX_MODE=SIM,

then,

I run the sgx enclave program at Intel Core Processor (Haswell),

and the enclave crashes, the crash info shows:

SIGILL: illegal instruction
PC=0x7fb4f219f4b0 m=3 sigcode=2;

why?

Can the enclave(SIM) not run at Intel Core Processor (Haswell) ?

Should I compile my sgx enclave program at Intel Core Processor (Haswell) and also run it at Intel Core Processor (Haswell) ?

Hello pp_monkeyking,

Yes, it is best to compile your program on the Haswell system so that it can find all of the relevant SGX simulation libraries in the system.
