# NAME

`iasl` —
Intel ASL compiler and disassembler (iASL)

# SYNOPSIS

`iasl` | [options] ⟨input file⟩

# DESCRIPTION

The `iasl` is a fully-featured compiler for the ACPI Source Language (ASL). It translates ASL to ACPI Machine Language (AML), but `iasl` can also act as a disassembler, translating AML to ASL.

# OPTIONS

## Global

`-@` file
  Specify command file.
`-I` dir
  Specify additional include directory.

## General Output

`-p` prefix
  Specify a path or filename prefix for all output files.
`-va`
  Disable all errors and warnings in the summary.
`-vi`
  Use less verbose errors and warnings.
`-vo`
  Enable optimization comments.
`-vr`
  Disable remarks.
`-vs`
  Disable signon.
`-w` 1 | 2 | 3
  Set warning reporting level.

## AML Output Files

`-s` a | c
  Create AML in assembler (*.asm) or C (*.c) source file.
`-i` a | c
  Create assembler (*.inc) or C (*.h) include file.
`-t` a | c
  Create AML in assembler or C hex table (*.hex).

## AML Code Generation

`-oa`
  Disable all optimizations (compatibility mode).
`-of`
  Disable constant folding.
`-oi`
  Disable integer optimization to operation codes.
`-on`
  Disable named reference string optimization.
`-r` revision
  Override table header revision (1-255).

## Listings

`-l`
  Create mixed, ASL and AML, listing file (*.lst).
`-ln`
  Create namespace file (*.nsp).
`-ls`
  Create combined source file (*.src).

## AML Disassembler

`-d` file
  Disassemble binary ACPI table to a file (*.dsl).
`-dc` file
  Disassemble AML and immediately compile it.
`-e` f1, f2
  Include ACPI table(s) for external symbol resolution.
`-2`
  Emit ACPI 2.0 compatible ASL code.
`-g`
  Get ACPI tables and write to files (*.dat).

## Help

`-h`
