# pbc\_disassemble(1)

parrot bytecode disassembler

## NAME

pbc\_disassemble - parrot bytecode disassembler

## SYNOPSIS

pbc\_disassemble \[-bh?\] \[--bare\|--header-only\] \[-o outfile\] \[file.pbc\]

## DESCRIPTION

`"pbc_disassemble"` translates Parrot bytecode (`"PBC"`) into Parrot assembly language (`"PASM"`).

`"file.pbc"` is the bytecode file to disassemble. If a file is not specified, the bytecode will be read from `"stdin"`. Additionally, if the `"-o"` switch is not given, the output is displayed to `"stdout"`.

## OPTIONS

- **-?**, **--help**

  Displays usage and help information.

- **-b**, **--bare**

  Displays bare PASM without the header and left column.

- **-h**, **--header-only**

  Displays only the constants table header.

- **-o** filename, **--output** filename

  Writes output to `"filename"`.

## STATIC FUNCTIONS

- "int main(int argc, const char \*argv\[\])"

  Execution entry point. Starts up an interpreter, loads the bytecode from the command-line, and disassembles it.

- "static void help(void)"

  Prints out the user help information and exits.

- "static void show\_last\_error\_and\_exit(Parrot\_PMC interp)"

  Prints out the `"interp"`'s last error and exits.

Reini Urban: Renamed from disassemble to pbc\_disassemble (2008-07-03).\
              Add options: help, -h, -o, --debug, --bare (2009-01-29)\
              Force option 1 for passing version check (2009-03-07)

Kevin Polulak (soh\_cah\_toa): Updated to use embedding API, moved source file\
                              to frontend/pbc\_disassemble, and cleaned up\
                              source code and perldoc. (2011-06-19)
