     iasl -- Intel ACPI	compiler/decompiler

     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

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

	   +o   Full support for	the ACPI 2.0b Specification including ASL
	       grammar elements	and operators.
	   +o   Extensive compiler syntax and semantic error checking, espe-
	       cially in the area of control methods. This reduces the number
	       of errors that are not discovered until the AML code is actu-
	       ally interpreted	(i.e., the compile-time	error checking reduces
	       the number of run-time errors.)
	   +o   Multiple	types of output	files, including formatted listing
	       files with intermixed source, several types of AML files, and
	       error messages.

     -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

     acpi(4), acpidump(8)

     The iasl utility is provided with Intel ACPI-CA.  It first	appeared in
     FreeBSD 5.2.

     The iasl utility was written by Intel.  This manual page was written by
     Nate Lawson.
