# fcml-disasm(1)

single-line disassembler

## NAME

fcml-disasm - single-line disassembler

## SYNOPSIS

**fcml-disasm** \[**-s**\] \[**-e**\] \[**-rc**\] \[**-rh**\] \[**-rz**\] \[**-rs**\] \[**-gas**\] \[**-asa**\<*size*\>\] \[**-osa**\<*size*\>\] **-m**\<*size*\> **-ip** \<*address*\> \<*code*\>

## DESCRIPTION

**fcml-disasm** is a single-line disassembler for Intel *i*AP*x*86, IA-32 and EM64T CPUs, and compatible CPUs from other manufacturers.

It displays all possible interpretations of the given machine code.

## OPTIONS

**fcml-disasm** accepts the following options:

- **-s**

  Prefer short instruction forms.

- **-e**

  Extend displacement sizes to address size attribute.

- **-rc**

  Render instruction code.

- **-rh**

  Render immediate values and displacements as hexadecimal.

- **-rz**

  Remove leading zeroes.

- **-rs**

  Render segment prefixes even when they are optional.

- **-gas**

  Use GNU Assembler dialect (also known as AT&T). The Intel dialect is used by default.

- **-asa**\<*size*\>

  Specify the size of the address size attribute (16, 32 or 64 for respectively 16, 32 and 63 bits).

- **-osa**\<*size*\>

  Specify the size of the operand size attribute (16, 32 or 64 for respectively 16, 32 and 63 bits).

- **-m**\<*size*\>

  Specify the addressing mode (16, 32 or 64).

- **-ip** \<*address*\>

  Specify the instruction pointer address (IP, EIP or RIP).
