As seen at :
https://gcc.gnu.org/onlinedocs/gcc/x86-Built-in-Functions.html
The example there seems to suggest that I could do this :
__builtin_cpu_init ();
if ( __builtin_cpu_is ("corei7") ){
fprintf ( stdout, "Intel Core i7 CPU. \n" );
} else {
fprintf ( stdout, " NOT Intel Core i7 CPU. \n" );
}
However I get an odd result from my Debian machine here when I try to
check for every possible option :
Just guessing: are you maybe calling __builtin_cpu_init() multiple times?
Though it shouldn't make a difference, IMO.
Tried that once before calling "__builtin_cpu_is" and also tried it
every time and it makes no difference.
