The selection of the algorithm is fairly complex and depends on the
specific processor you are tuning for. See decide_alg in
config/i386/i
Hi Folks,
GCC 4.5.1 20100924 "-Os -minline-all-stringops" on Core i7
int
main( int argc, char *argv[] )
{
int i, a[256], b[256];
for( i = 0; i < 256; ++i ) // discourage optimization
a[i] = rand();
memcpy( b, a, argc * sizeof(int) );
printf( "%d\n", b[rand()] ); // discourag
