// BSWAP is currently expanded. The following is a more efficient
|
|
// - for < sm_20, use vector scalar mov, as tesla support native 16-bit register
|
|
// - for sm_20, use pmpt (use vector scalar mov to get the pack and
|
|
// unpack). sm_20 supports native 32-bit register, but not native 16-bit
|
|
// register.
