NAME
     iasl -- Intel ACPI compiler/decompiler

SYNOPSIS
     iasl [-cefghl] [-b type] [-d file] [-dc file] [-hc] [-hr] [-i type] [-ln]
	  [-ls] [-oa] [-of] [-oi] [-on] [-ot] [-p prefix] [-s type] [-t type]
	  [-vi] [-vo] [-vr] [-vs] [-x level] input-file

DESCRIPTION
     The  iasl	utility  is a compiler/decompiler for ACPI Source Language (ASL)
     and ACPI Machine Language (AML).  Major features of iasl include:

	   *   Full support for the ACPI 2.0b Specification including ASL  gram-
	       mar elements and operators.
	   *   Extensive compiler syntax and semantic error checking, especially
	       in the area of control methods. This reduces the number of errors
	       that  are  not  discovered  until the AML code is actually inter-
	       preted (i.e., the compile-time error checking reduces the  number
	       of run-time errors.)
	   *   Multiple types of output files, including formatted listing files
	       with  intermixed  source,  several  types of AML files, and error
	       messages.

OPTIONS
     -b p|t|b
	     Create compiler debug/trace file (*.txt). Types: Parse/Tree/Both

     -c      Parse only, no output generation

     -d file
	     Disassemble AML to ASL source code file (*.dsl)

     -dc file
	     Disassemble AML and immediately compile it (Obtain DSDT  from  cur-
	     rent system if no input file)

     -e      Generate External() statements for unresolved symbols

     -f      Ignore errors, force creation of AML output file(s)

     -g      Get ACPI tables and write to files (*.dat)

     -h      Additional help and compiler debug options

     -hc     Display operators allowed in constant expressions

     -hr     Display ACPI reserved method names

     -i a|c  Create assembler or C include file (*.inc or *.h)

     -l      Create mixed listing file (ASL source and AML) (*.lst)

     -ln     Create namespace file (*.nsp)

     -ls     Create combined source file (expanded includes) (*.src)

     -oa     Disable all optimizations (compatibility mode)

     -of     Disable constant folding

     -oi     Disable integer optimization to Zero/One/Ones

     -on     Disable named reference string optimization

     -ot     Display compile times

     -p prefix
	     Specify filename prefix for all output files (including .aml)

     -s a|c  Create AML in assembler or C source file (*.asm or *.c)

     -t a|c  Create AML in assembler or C hex table (*.hex)

     -vi     Less verbose errors and warnings for use with IDEs

     -vo     Enable optimization comments

     -vr     Disable remarks

     -vs     Disable signon

     -x level
	     Set debug level for trace output
