// archtecture.
register %{
//----------Architecture Description Register Definitions----------------------
// General Registers
// "reg_def" name ( register save type, C convention save type,
// ideal register type, encoding );
// Register Save Types:
//
// NS = No-Save: The register allocator assumes that these registers
// can be used without saving upon entry to the method, &
// that they do not need to be saved at call sites.
//
// SOC = Save-On-Call: The register allocator assumes that these registers
// can be used without saving upon entry to the method,
// but that they must be saved at call sites.
//
// SOE = Save-On-Entry: The register allocator assumes that these registers
// must be saved before using them upon entry to the
// method, but they do not need to be saved at call
// sites.
//
// AS = Always-Save: The register allocator assumes that these registers
// must be saved before using them upon entry to the
// method, & that they must be saved at call sites.
//
// Ideal Register Type is used to determine how to save & restore a
// register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get
// spilled with LoadP/StoreP. If the register supports both, use Op_RegI.
//
// The encoding number is the actual bit-pattern placed into the opcodes.
// General Registers
// R8-R15 must be encoded with REX. (RSP, RBP, RSI, RDI need REX when
// used as byte registers)
// Previously set RBX, RSI, and RDI as save-on-entry for java code
// Turn off SOE in java-code due to frequent use of uncommon-traps.
// Now that allocator is better, turn on RSI and RDI as SOE registers.

// which participate in fixed calling sequences should come last.

//----------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.
encode %{
// Build emit functions for each basic byte or larger field in the
// intel encoding scheme (opcode, rm, sib, immediate), and call them
// from C++ code in the enc_class source block. Emit functions will

//----------PEEPHOLE RULES-----------------------------------------------------
// These must follow all instruction definitions as they use the names
// defined in the instructions definitions.
//
// peepmatch ( root_instr_name [preceding_instruction]* );
//
// peepconstraint %{
// (instruction_number.operand_name relational_op instruction_number.operand_name
// [, ...] );
// // instruction numbers are zero-based using left to right order in peepmatch
//
// peepreplace ( instr_name ( [instruction_number.operand_name]* ) );
// // provide an instruction_number.operand_name for each operand that appears
// // in the replacement instruction's match rule
//
// ---------VM FLAGS---------------------------------------------------------
//
// All peephole optimizations can be turned off using -XX:-OptoPeephole
//
// Each peephole rule is given an identifying number starting with zero and
// increasing by one in the order seen by the parser. An individual peephole
// can be enabled, and all others disabled, by using -XX:OptoPeepholeAt=#
// on the command-line.
//
// ---------CURRENT LIMITATIONS----------------------------------------------
//
// Only match adjacent instructions in same basic block
// Only equality constraints
// Only constraints between operands, not (0.dest_reg == RAX_enc)
// Only one replacement instruction
//
// ---------EXAMPLE----------------------------------------------------------
//
// // pertinent parts of existing instructions in architecture description
// instruct movI(rRegI dst, rRegI src)
// %{
// match(Set dst (CopyI src));
// %}
//
// instruct incI_rReg(rRegI dst, immI1 src, rFlagsReg cr)
// %{
// match(Set dst (AddI dst src));
// effect(KILL cr);
// %}
//
// // Change (inc mov) to lea
// peephole %{
// // increment preceeded by register-register move
// peepmatch ( incI_rReg movI );
// // require that the destination register of the increment
// // match the destination register of the move
// peepconstraint ( 0.dst == 1.dst );
// // construct a replacement instruction that sets
// // the destination to ( move's source register + one )
// peepreplace ( leaI_rReg_immI( 0.dst 1.src 0.src ) );
// %}
//
// Implementation no longer uses movX instructions since
// machine-independent system no longer uses CopyX nodes.
