-//----------REGISTER DEFINITION BLOCK------------------------------------------
-// This information is used by the matcher and the register allocator to
-// describe individual registers and classes of registers within the target
-// archtecture.
-register %{
-//----------Architecture Description Register Definitions----------------------
-// General Registers
-// "reg_def" name ( register save type, C convention save type,
-// ideal register type, encoding, vm name );
-// 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.
-// FIXME: above comment seems wrong. Spill done through MachSpillCopyNode
-//
-// The encoding number is the actual bit-pattern placed into the opcodes.

-// TODO: would be nice to keep track of high-word state:
-// zeroRegI --> RegL
-// signedRegI --> RegL
-// junkRegI --> RegL
-// how to tell C2 to treak RegI as RegL, or RegL as RegI?
