The numeric values should remain fixed 25 whenever possible. Thus, we assign them values explicitly here (to 26 allow gaps to form safely), and the disassembly table in 27 agentexpr.h behaves like an opcode map. If you want to see them 28 grouped logically, see doc/agentexpr.texi. 29 30 Each line is of the form: 31 32 DEFOP (name, size, data_size, consumed, produced, opcode) 33 34 NAME is the name of the operation. 35 SIZE is the number of argument bytes that the operation takes from 36 the bytecode stream. 37 DATA_SIZE is the size of data operated on, in bits, for operations 38 that care (ref and const). It is zero otherwise. 39 CONSUMED is the number of stack elements consumed. 40 PRODUCED is the number of stack elements produced. 41 OPCODE is the operation's encoding. */ 42 43DEFOP (float, 0, 0, 0, 0, 0x01) 44DEFOP (add, 0, 0, 2, 1, 0x02) 45DEFOP (sub, 0, 0, 2, 1, 0x03) 46DEFOP (mul, 0, 0, 2, 1, 0x04) 47DEFOP (div_signed, 0, 0, 2, 1, 0x05) 48DEFOP (div_unsigned, 0, 0, 2, 1, 0x06) 49DEFOP (rem_signed, 0, 0, 2, 1, 0x07) 50DEFOP (rem_unsigned, 0, 0, 2, 1, 0x08) 51DEFOP (lsh, 0, 0, 2, 1, 0x09) 52DEFOP (rsh_signed, 0, 0, 2, 1, 0x0a) 53DEFOP (rsh_unsigned, 0, 0, 2, 1, 0x0b) 54DEFOP (trace, 0, 0, 2, 0, 0x0c) 55DEFOP (trace_quick, 1, 0, 1, 1, 0x0d) 56DEFOP (log_not, 0, 0, 1, 1, 0x0e) 57DEFOP (bit_and, 0, 0, 2, 1, 0x0f) 58DEFOP (bit_or, 0, 0, 2, 1, 0x10) 59DEFOP (bit_xor, 0, 0, 2, 1, 0x11) 60DEFOP (bit_not, 0, 0, 1, 1, 0x12) 61DEFOP (equal, 0, 0, 2, 1, 0x13) 62DEFOP (less_signed, 0, 0, 2, 1, 0x14) 63DEFOP (less_unsigned, 0, 0, 2, 1, 0x15) 64DEFOP (ext, 1, 0, 1, 1, 0x16) 65DEFOP (ref8, 0, 8, 1, 1, 0x17) 66DEFOP (ref16, 0, 16, 1, 1, 0x18) 67DEFOP (ref32, 0, 32, 1, 1, 0x19) 68DEFOP (ref64, 0, 64, 1, 1, 0x1a) 69DEFOP (ref_float, 0, 0, 1, 1, 0x1b) 70DEFOP (ref_double, 0, 0, 1, 1, 0x1c) 71DEFOP (ref_long_double, 0, 0, 1, 1, 0x1d) 72DEFOP (l_to_d, 0, 0, 1, 1, 0x1e) 73DEFOP (d_to_l, 0, 0, 1, 1, 0x1f) 74DEFOP (if_goto, 2, 0, 1, 0, 0x20) 75DEFOP (goto, 2, 0, 0, 0, 0x21) 76DEFOP (const8, 1, 8, 0, 1, 0x22) 77DEFOP (const16, 2, 16, 0, 1, 0x23) 78DEFOP (const32, 4, 32, 0, 1, 0x24) 79DEFOP (const64, 8, 64, 0, 1, 0x25) 80DEFOP (reg, 2, 0, 0, 1, 0x26) 81DEFOP (end, 0, 0, 0, 0, 0x27) 82DEFOP (dup, 0, 0, 1, 2, 0x28) 83DEFOP (pop, 0, 0, 1, 0, 0x29) 84DEFOP (zero_ext, 1, 0, 1, 1, 0x2a) 85DEFOP (swap, 0, 0, 2, 2, 0x2b) 86DEFOP (getv, 2, 0, 0, 1, 0x2c) 87DEFOP (setv, 2, 0, 0, 1, 0x2d) 88DEFOP (tracev, 2, 0, 0, 1, 0x2e) 89/* We need something here just to make the tables come out ok. */ 90DEFOP (invalid, 0, 0, 0, 0, 0x2f) 91DEFOP (trace16, 2, 0, 1, 1, 0x30) 92/* We need something here just to make the tables come out ok. */ 93DEFOP (invalid2, 0, 0, 0, 0, 0x31) 94/* The "consumed" number for pick is wrong, but there's no way to 95 express the right thing. */ 96DEFOP (pick, 1, 0, 0, 1, 0x32) 97DEFOP (rot, 0, 0, 3, 3, 0x33) 98
