[gem5-users] Problem Running SPEC CPU2017 benchmarks

[Samon Shivastar]

Hi Everyone,
I am getting error while trying to run SPEC CPU2017 benchmarks on gem5 and
getting the following error:

panic: Unrecognized/invalid instruction executed:

{
leg = 0x10,
rex = 0,
vex/xop = 0x5,
op = {
type = three byte 0f3a,
op = 0x18,
},
modRM = 0,
sib = 0,
immediate = 0,
displacement = 0
dispSize = 0
}

This error has been discussed on this forum before:
https://gem5-users.gem5.narkive.com/jO22f7kV/spec2017-on-gem5-se-mode#post5

to which Gabe replied:
"The instruction it's complaining about is an AVX-512 instruction (VINSERT)
which is not supported by gem5. You need to tell your compiler not to use
those instructions."

My question is: How exactly I can tell my compiler not to use those
instructions?

Any help would be appreciated.

Thanks
Sam
