One of compare, const, free, jabs, jrel, local, name, nargs inst_size - number of bytes the instruction occupies arg - numeric argument to operation (if any), otherwise None argval - resolved arg value (if known), otherwise same as arg argrepr - human readable description of operation argument has_arg - True opcode takes an argument. In that case, argval and argepr will have that value. False if this opcode doesn't take an argument. In that case, don't look at argval or argrepr. offset - start index of operation within bytecode sequence starts_line - line started by this opcode (if any), otherwise None is_jump_target - True if other code jumps to here, 'loop' if this is a loop beginning, which in Python can be determined jump to an earlier offset. Otherwise False has_extended_arg - True if the instruction was built from EXTENDED_ARG opcodes fallthrough - True if the instruction can (not must) fall through to the next instruction. Note conditionals are in this category, but returns, raise, and unconditional jumps are not Fc Csg}|rtddddg}|r|jdk r|rjd|}|j||j|jd||jr|jd|dqd |}|j||jn|jd|d|r| r|jd n |jd |jr|s|jd qd |jg|}|js|jdn |jd|s|jt|jjd|rd|j}|jdkr8|d 7}|jdkrj|j r`|d|j d7}n|d7}n(|jdkr|d|j d?|j df7}|j|d|j|j j t |j dk r|j} |r|jdkr|jdt|j n|jdkr|j|j |j} |jdt| n|j|kr>|jd| d} np|jdkrntjd|  rn|jd| d} n@|jdkrtjd|  r|jd| d} n|jt|j n"|o| s|jt|j jt| r|jd| dj|jS)!zFormat instruction details for inclusion in disassembly output *lineno_width* sets the width of the line number field (0 omits it) *mark_as_current* inserts a '-->' marker arrow as part of the line namelocalZcomparefreeNz%%%dd:  z%%%dd:z-->z z>>zL%d: z z|%02xrz %02xz 00z %02x %02x|jabsLjrelz(%s)constz\srz )set starts_lineappendis_jump_targetoffsetreprrjustopcodeZ inst_sizehas_argargopnameljust _OPNAME_WIDTHargreproptypestrresearch _OPARG_WIDTHjoinrstrip) self lineno_widthmark_as_currentZ asm_formatZ show_bytesfieldsZindexed_operand lineno_fmtZ hex_bytecoder#argvalr1M/home/psgendb/BIRCHDEV/python/lib/python3.6/site-packages/xdis/instruction.py disassembleLs                    zInstruction.disassemblecCs |jdkS)zB Return True if instruction is some sort of jump. rr)rr)r$)r+r1r1r2is_jumpszInstruction.is_jumpcCs|jo|j|jkS)z> Return True if instruction is jump backwards )r4rr0)r+r1r1r2 jumps_forwardszInstruction.jumps_forwardN)rFFF)__name__ __module__ __qualname____doc__r3r4r5r1r1r1r2r.s ^r)r9r& collectionsrrr rrr0r#rrrrZhas_extended_argr"r(rr1r1r1r2s(
