Screenshot of X Term after cat /proc/cpuinfo on Arch Linux x86
Currently I own a device (Asus ZenFone 2) with the Intel Atom Z3580 processor,
which is identified as family 6, model 90 by doing cat /proc/cpuinfo. LLVM
refuses to recognize it as such and there is no SSE 4.1/4.2, returning it as a
generic processor, as seen in hosts.cpp in lines 380-384 as follows:
// Atom Silvermont codes from the Intel software optimization guide.
case 55:
case 74:
case 77:
return "silvermont";
There is no "case 90:", leaving the switch statement fall to the default cases.</pre>
