IASL(8) System Manager's Manual IASL(8) NAME iasl -- Intel ACPI compiler/decompiler SYNOPSIS iasl [-2cefghl] [-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] [-w 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 3.0b 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 er- rors that are not discovered until the AML code is actually in- terpreted (i.e., the compile-time error checking reduces the num- ber 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 -2 Emit ACPI 2.0 compatible ASL code. -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. -w level Set warning level.
