46 This is the name of the C language compiler as required by the
52 compiler accepts the following options:
53 .Bl -tag -width indent
55 Suppress the link-edit phase of the compilation, and do not remove any
56 object files that are produced.

83 will be undefined regardless of the order of the options.
86 option may be specified more than once.
88 Copy C-language source files to the standard output, expanding all
89 preprocessor directives; no compilation will be performed.
91 Produce symbolic information in the object or executable files.
93 Change the algorithm for searching for headers whose names are not
94 absolute pathnames to look in the directory named by the
96 pathname before looking in the usual places.
98 names are enclosed in double-quotes
100 will be searched for first
101 in the directory of the file with the
106 options, and last in the usual places.
107 For headers whose names are enclosed in angle brackets
110 will be searched for only in directories named in
112 options and then in the usual places.
115 options shall be searched in the order specified.
118 option may be specified more than once.
119 .It Fl L Ar directory
120 Change the algorithm of searching for the libraries named in the
122 objects to look in the directory named by the
124 pathname before looking in the usual places.
127 options will be searched in the order specified.

154 An operand is either in the form of a pathname or the form
157 At least one operand of the pathname form needs to be specified.
158 Supported operands are of the form:
159 .Bl -tag -offset indent -width ".Fl l Ar library"
161 A C-language source file to be compiled and optionally linked.
162 The operand must be of this form if the
166 A library of object files, as produced by
168 passed directly to the link editor.
170 An object file produced by
172 and passed directly to the link editor.
174 Search the library named
175 .Pa lib Ns Ar library Ns Pa .a .
176 A library will be searched when its name is encountered, so the
179 operand is significant.
