62.Sh DESCRIPTION
63The
64.Nm
65utility is a compiler/decompiler for ACPI Source Language (ASL)
66and ACPI Machine Language (AML).
67Major features of
68.Nm
69include:
70.Bl -bullet -offset indent
71.It
72Full support for the ACPI 3.0b Specification including ASL grammar
73elements and operators.
74.It
75Extensive compiler syntax and semantic error checking, especially in
76the area of control methods.
77This reduces the number of errors that are
78not discovered until the AML code is actually interpreted (i.e., the
79compile-time error checking reduces the number of run-time errors).
80.It
81Multiple types of output files, including formatted listing files with
82intermixed source, several types of AML files, and error messages.
83.El
84.Sh OPTIONS
85.Bl -tag -width indent
86.It Fl 2
87Emit ACPI 2.0 compatible ASL code.
88.It Fl b Sm Cm p | t | b Sm
89Create compiler debug/trace file
90.Pq Pa *.txt .
91Types: Parse/Tree/Both.
92.It Fl c
93Parse only, no output generation.
94.It Fl d Ar file
95Disassemble AML to ASL source code file
96.Pq Pa *.dsl .
97.It Fl dc Ar file
98Disassemble AML and immediately compile it.
99(Obtain DSDT from current system if no input file.)
100.It Fl e
101Generate
102.Fn External
103statements for unresolved symbols.
104.It Fl f
105Ignore errors, force creation of AML output file(s).
106.It Fl g
107Get ACPI tables and write to files
108.Pq Pa *.dat .
109.It Fl h
110Additional help and compiler debug options.
111.It Fl hc
112Display operators allowed in constant expressions.
113.It Fl hr
114Display ACPI reserved method names.
115.It Fl i Sm Cm a | c Sm
116Create assembler or C include file
117.Pa ( *.inc
118or
119.Pa *.h ) .
120.It Fl l
121Create mixed listing file (ASL source and AML)
122.Pq Pa *.lst .
123.It Fl ln
124Create namespace file
125.Pq Pa *.nsp .
126.It Fl ls
127Create combined source file (expanded includes)
128.Pq Pa *.src .
129.It Fl oa
130Disable all optimizations (compatibility mode).
131.It Fl of
132Disable constant folding.
133.It Fl oi
134Disable integer optimization to Zero/One/Ones.
135.It Fl on
136Disable named reference string optimization.
137.It Fl ot
138Display compile times.
139.It Fl p Ar prefix
140Specify filename prefix for all output files (including
141.Pa .aml ) .
142.It Fl s Sm Cm a | c Sm
143Create AML in assembler or C source file
144.Pa ( *.asm
145or
146.Pa *.c ) .
147.It Fl t Ar a|c
148Create AML in assembler or C hex table
149.Pq Pa *.hex .
150.It Fl vi
151Less verbose errors and warnings for use with IDEs.
152.It Fl vo
153Enable optimization comments.
154.It Fl vr
155Disable remarks.
156.It Fl vs
157Disable signon.
158.It Fl x Ar level
159Set debug level for trace output.
160.It Fl w Ar level
161Set warning level.
