61.Sh DESCRIPTION
62The
63.Nm
64utility is a compiler/decompiler for ACPI Source Language (ASL)
65and ACPI Machine Language (AML).  Major features of
66.Nm
67include:
68.Pp
69.Bl -bullet -compact -offset indent
70.It
71Full support for the ACPI 2.0b Specification including ASL grammar
72elements and operators.
73.It
74Extensive compiler syntax and semantic error checking, especially in
75the area of control methods. This reduces the number of errors that are
76not discovered until the AML code is actually interpreted (i.e., the
77compile-time error checking reduces the number of run-time errors.)
78.It
79Multiple types of output files, including formatted listing files with
80intermixed source, several types of AML files, and error messages.
81.El
82.Sh OPTIONS
83.Bl -tag -width indent
84.It Fl b Ar p|t|b
85Create compiler debug/trace file (*.txt). Types: Parse/Tree/Both
86.It Fl c
87Parse only, no output generation
88.It Fl d Ar file
89Disassemble AML to ASL source code file (*.dsl)
90.It Fl dc Ar file
91Disassemble AML and immediately compile it
92(Obtain DSDT from current system if no input file)
93.It Fl e
94Generate External() statements for unresolved symbols
95.It Fl f
96Ignore errors, force creation of AML output file(s)
97.It Fl g
98Get ACPI tables and write to files (*.dat)
99.It Fl h
100Additional help and compiler debug options
101.It Fl hc
102Display operators allowed in constant expressions
103.It Fl hr
104Display ACPI reserved method names
105.It Fl i Ar a|c
106Create assembler or C include file (*.inc or *.h)
107.It Fl l
108Create mixed listing file (ASL source and AML) (*.lst)
109.It Fl ln
110Create namespace file (*.nsp)
111.It Fl ls
112Create combined source file (expanded includes) (*.src)
113.It Fl oa
114Disable all optimizations (compatibility mode)
115.It Fl of
116Disable constant folding
117.It Fl oi
118Disable integer optimization to Zero/One/Ones
119.It Fl on
120Disable named reference string optimization
121.It Fl ot
122Display compile times
123.It Fl p Ar prefix
124Specify filename prefix for all output files (including .aml)
125.It Fl s Ar a|c
126Create AML in assembler or C source file (*.asm or *.c)
127.It Fl t Ar a|c
128Create AML in assembler or C hex table (*.hex)
129.It Fl vi
130Less verbose errors and warnings for use with IDEs
131.It Fl vo
132Enable optimization comments
133.It Fl vr
134Disable remarks
135.It Fl vs
136Disable signon
137.It Fl x Ar level
138Set debug level for trace output
