60.Sh DESCRIPTION
61The
62.Nm
63utility is a compiler/decompiler for ACPI Source Language (ASL)
64and ACPI Machine Language (AML).
65Major features of
66.Nm
67include:
68.Bl -bullet -offset indent
69.It
70Full support for the ACPI 3.0b Specification including ASL grammar
71elements and operators.
72.It
73Extensive compiler syntax and semantic error checking, especially in
74the area of control methods.
75This 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 2
85Emit ACPI 2.0 compatible ASL code.
86.It Fl b Sm Cm p | t | b Sm
87Create compiler debug/trace file
88.Pq Pa *.txt .
89Types: Parse/Tree/Both.
90.It Fl c
91Parse only, no output generation.
92.It Fl d Ar file
93Disassemble AML to ASL source code file
94.Pq Pa *.dsl .
95.It Fl dc Ar file
96Disassemble AML and immediately compile it.
97(Obtain DSDT from current system if no input file.)
98.It Fl e
99Generate
100.Fn External
101statements for unresolved symbols.
102.It Fl f
103Ignore errors, force creation of AML output file(s).
104.It Fl g
105Get ACPI tables and write to files
106.Pq Pa *.dat .
107.It Fl h
108Additional help and compiler debug options.
109.It Fl hc
110Display operators allowed in constant expressions.
111.It Fl hr
112Display ACPI reserved method names.
113.It Fl i Sm Cm a | c Sm
114Create assembler or C include file
115.Pa ( *.inc
116or
117.Pa *.h ) .
118.It Fl l
119Create mixed listing file (ASL source and AML)
120.Pq Pa *.lst .
121.It Fl ln
122Create namespace file
123.Pq Pa *.nsp .
124.It Fl ls
125Create combined source file (expanded includes)
126.Pq Pa *.src .
127.It Fl oa
128Disable all optimizations (compatibility mode).
129.It Fl of
130Disable constant folding.
131.It Fl oi
132Disable integer optimization to Zero/One/Ones.
133.It Fl on
134Disable named reference string optimization.
135.It Fl ot
136Display compile times.
137.It Fl p Ar prefix
138Specify filename prefix for all output files (including
139.Pa .aml ) .
140.It Fl s Sm Cm a | c Sm
141Create AML in assembler or C source file
142.Pa ( *.asm
143or
144.Pa *.c ) .
145.It Fl t Ar a|c
146Create AML in assembler or C hex table
147.Pq Pa *.hex .
148.It Fl vi
149Less verbose errors and warnings for use with IDEs.
150.It Fl vo
151Enable optimization comments.
152.It Fl vr
153Disable remarks.
154.It Fl vs
155Disable signon.
156.It Fl x Ar level
157Set debug level for trace output.
158.It Fl w Ar level
159Set warning level.
