#
# Any line that doesn't have a-z in the 1st column is a comment.
#
# The first column is the name of the opcode.
#
# The second column is the opcode's number, or "-" to assign the
# next available sequential number.
#
# The third column is the total length of the instruction.  We use 0
# for opcodes of variable length, as well as unrecognized/unused
# opcodes.
#
# The fourth and fifth column give what the opcode pops off the stack, and
# what it then pushes back onto the stack
#    -       <no effect on stack>   
#    I       integer
#    L       long integer
#    F       float
#    D       double float
#    A       address [array or object]
#    O       object only
#    R       return address (for jsr)
#    a       integer, array, or object
#    ?       unknown
#    [I], [L], [F], [D], [A], [B], [C], [?]
#            array of integer, long, float, double, address, bytes, 
#                  chars, or anything
#    1,2,3,4,+ used by stack duplicating/popping routines.  
# 
# 1,2,3,4 represent >>any<< stack type except long or double.  Two numbers
# separated by a + (in the third column) indicate that the two, together, can
# be used for a double or long.  (Or they can represent two non-long items).
#
# The sixth column has a comma-separated list of attributes of the
# opcode. These are necessary in the stackmap computation dataflow 
# analysis.
#
# GC    -- a GC point
# CGC   -- a conditional GC point; only if the thread is at a quickening point
# BR    -- a branch
# EXC   -- May throw exception
# INV   -- A method invocation
# NFLW  -- An instruction that doesn't let control flow through
#           (returns, athrow, switches, goto, ret)
# QUICK -- A quick instruction, re-written by the interpreter.
# RET   -- A return opcode.
# FP    -- A floating point opcode
# -     -- No special attributes to speak of
#            
# The seventh column is a "simplification" of the opcode, for opcode
# sequence measurements (see CVM_INSTRUCTION_COUNTING in executejava.c).
#
# The eigth column has the attribute of CVMJITIROpcodeTag.
# The ninth column has the attribute of type tag listed in typeid.h.
# The tenth column has the attribute of value representing constant value,
# local variable number, etc.
