usage: <R>fxos<> [<R>library<>|<R>info<>|<R>disasm<>|<R>analyze<>]

fxos is a reverse-engineering tool that disassembles and analyzes SuperH
programs and OS dumps for CASIO calculators of the fx-9860G and fx-CG 50
families, using an editable database of platform, syscall, and OS knowledge.

General options:
  <R>-3<>, <R>--sh3<>         Assume SH3 OS and platform (default: SH4)
  <R>-4<>, <R>--sh4<>         Assume SH4 OS and platform (default: SH4)
  <R>-v<>, <R>--verbose<>     Print logs about what's happening

<R>fxos library<> [<R>-t<>] [<R>-a<>]
  Prints out the contents of the library. If an option is set, the results are
  printed in a simple easily-parsable form without header.

  Selectors:
    <R>-t<>, <R>--targets<>     Print all targets
    <R>-a<>, <R>--asm<>         Print all assembler instruction sets

<R>fxos info<> <<P>TARGET<>>
  Print adentification and basic information about an OS image: version,
  platform, date, checksums...

  Target specification:
    <<P>TARGET-NAME<>>     Named target in library (eg. "fx@3.10")
    <R>-f<> <<P>FILE<>>         Arbitrary file which is loaded as ROM

<R>fxos disasm<> <<P>TARGET<>> <<P>LOCATION<>> [options...]
  Disassemble and annotate code with relative address targets, syscalls,
  control flow, propagated constants and hints about memory structure.

  Location specifiers:
    <<P>ADDRESS<>>         Start disassembling at this address (hexa)
    <<P>ADDRESS<>>:<<P>LEN<>>   Disassemble exactly the specified region. <P>len<> is an
                      hexadecimal number optionally followed by k, M, or G.
    %<<P>SYSCALL-ID<>>     Start disassembling at this syscall's address (hexa)
    <<P>SYMBOL<>>          Disassemble this library symbol (typically syscall name).
                      A name which is valid hexadecimal is treated as <P>ADDRESS<>.
  Disassembly options:
    <R>-p<> <<P>PASSES<>>         Execute the specified comma-separated list of passes
  Available passes:
    cfg               Build the control flow graph (always required)
    pcrel             Resolve PC-relative references as their target address
    cstprop           Propagate constants by abstract interpretation
    syscall           Annotate code with reverse syscalls

  The default sequence of passes is <W>cfg,pcrel,cstprop,syscall<>. When
  disassembling a function (ie. no size specified on the command-line), the cfg
  pass is always executed to obtain the code of the function.
