DESCRIPTION

The iasl utility is a compiler/decompiler for ACPI Source

Language (ASL)
and ACPI Machine Language (AML). Major features of iasl in

clude:

+o Full support for the ACPI 2.0b Specification in

cluding ASL

grammar elements and operators.

+o Extensive compiler syntax and semantic error

checking, espe

cially in the area of control methods. This re

duces 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 format

ted 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
current system if no input file.)

-e Generate External() statements for unresolved sym

bols.

-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 (in

cluding .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.
