//----------ENCODING BLOCK-----------------------------------------------------
// This block specifies the encoding classes used by the compiler to output
// byte streams. Encoding classes are parameterized macros used by
// Machine Instruction Nodes in order to generate the bit encoding of the
// instruction. Operands specify their base encoding interface with the
// interface keyword. There are currently supported four interfaces,
// REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an
// operand to generate a function which returns its register number when
// queried. CONST_INTER causes an operand to generate a function which
// returns the value of the constant when queried. MEMORY_INTER causes an
// operand to generate four functions which return the Base Register, the
// Index Register, the Scale Value, and the Offset Value of the operand when
// queried. COND_INTER causes an operand to generate six functions which
// return the encoding code (ie - encoding bits for the instruction)
// associated with each basic boolean condition for a conditional instruction.
//
// Instructions specify two basic values for encoding. Again, a function
// is available to check if the constant displacement is an oop. They use the
// ins_encode keyword to specify their encoding classes (which must be
// a sequence of enc_class names, and their parameters, specified in
// the encoding block), and they use the
// opcode keyword to specify, in order, their primary, secondary, and
// tertiary opcode. Only the opcode sections which a particular instruction
// needs for encoding need to be specified.

// Long Compare
//
// Currently we hold longs in 2 registers. Comparing such values efficiently
// is tricky. The flavor of compare used depends on whether we are testing
// for LT, LE, or EQ. For a simple LT test we can check just the sign bit.
// The GE test is the negated LT test. The LE test can be had by commuting
// the operands (yielding a GE test) and then negating; negate again for the
// GT test. The EQ test is done by ORcc'ing the high and low halves, and the
// NE test is negated from that.
// Due to a shortcoming in the ADLC, it mixes up expressions like:
// (foo (CmpI (CmpL X Y) 0)) and (bar (CmpI (CmpL X 0L) 0)). Note the
// difference between 'Y' and '0L'. The tree-matches for the CmpI sections
// are collapsed internally in the ADLC's dfa-gen code. The match for
// (CmpI (CmpL X Y) 0) is silently replaced with (CmpI (CmpL X 0L) 0) and the
// foo match ends up with the wrong leaf. One fix is to not match both
// reg-reg and reg-zero forms of long-compare. This is unfortunate because
// both forms beat the trinary form of long-compare and both are very useful
// on Intel which has so few registers.
