45 This is the name of the C language compiler as required by the
51 compiler accepts the following options:
52 .Bl -tag -width indent
54 Suppress the link-edit phase of the compilation, and do not remove any
55 object files that are produced.
56 .It Fl D Ar name Ns Op = Ns Ar value
57 Define name as if by a C-language
62 is given, a value of 1 will be used.
63 Note that in order to request a
64 translation as specified by

68 either in the source or using this option.
71 option has lower precedence than the
82 will be undefined regardless of the order of the options.
85 option may be specified more than once.
87 Copy C-language source files to the standard output, expanding all
88 preprocessor directives; no compilation will be performed.
90 Produce symbolic information in the object or executable files.
92 Change the algorithm for searching for headers whose names are not
93 absolute pathnames to look in the directory named by the
95 pathname before looking in the usual places.
97 names are enclosed in double-quotes
99 will be searched for first
100 in the directory of the file with the
105 options, and last in the usual places.
106 For headers whose names are enclosed in angle brackets
109 will be searched for only in directories named in
111 options and then in the usual places.
114 options shall be searched in the order specified.
117 option may be specified more than once.
118 .It Fl L Ar directory
119 Change the algorithm of searching for the libraries named in the
121 objects to look in the directory named by the
123 pathname before looking in the usual places.
126 options will be searched in the order specified.
129 option may be specified more than once.

140 Otherwise, enable optimizations at the specified level.
142 Produce object and/or executable files from which symbolic and other
143 information not required for proper execution has been removed

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