// Special Handling for 8-bit Operands and Operations
//
// PTX supports 8-bit signed and unsigned types, but does not support 8-bit
// operations (like add, shift, etc) except for ld/st/cvt. SASS does not have
// 8-bit registers.
//
// PTX ld, st and cvt instructions permit source and destination data operands
// to be wider than the instruction-type size, so that narrow values may be
// loaded, stored, and converted using regular-width registers.
//
// So in PTX generation, we
// - always use 16-bit registers in place in 8-bit registers.
// (8-bit variables should stay as 8-bit as they represent memory layout.)
// - for the following 8-bit operations, we sign-ext/zero-ext the 8-bit values
// before operation
// . div
// . rem
// . neg (sign)
// . set, setp
// . shr
//
// We are patching the operations by inserting the cvt instructions in the
// asm strings of the affected instructions.
//
// Since vector operations, except for ld/st, are eventually elementized. We
// do not need to special-hand the vector 8-bit operations.
//

// 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.
