     iasl -- Intel ACPI compiler/decompiler

SYNOPSIS    [Toc]    [Back]

     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    [Toc]    [Back]

     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, especially
 in the area of control methods. This reduces the number
	       of errors that are not discovered until the AML code is actually
 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.

OPTIONS    [Toc]    [Back]

     -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 current
 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
