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