ddcpuid

x86 CPU Identification tool

This was initially used internally, so it's pretty unfriendly.

The best way to use this module would be:

CPUINFO info;     // Important to let the struct init to zero!
getLeaves(info);  // Get maximum CPUID leaves (mandatory step before info)
getVendor(info);  // Get vendor string (mandatory step before info)
getInfo(info);    // Fill CPUINFO structure (optional)

Then checking the corresponding field:

if (info.ext.amx_xfd) {
  // Intel AMX is available
} else {
  // Feature unavailable
}

See the CPUINFO structure for available fields.

For more information, it's encouraged to consult the technical manual.

NOTICE: This is best used with DMD and LDC. Will crash on GDC -O1.
