This is +usually used to designate a different directory for the object file. +The default is the empty string. +.TP 5 +.B \-sstring +Starting string delimiter. +This option permits you to specify +a different string for +.B makedepend +to look for in the makefile. +.TP 5 +.B \-wwidth +Line width. +Normally, +.B makedepend +will ensure that every output line that it writes will be no wider than +78 characters for the sake of readability. +This option enables you to change this width. +.TP 5 +.B \-v +Verbose operation. +This option causes +.B makedepend +to emit the list of files included by each input file on standard output. +.TP 5 +.B \-m +Warn about multiple inclusion. +This option causes +.B makedepend +to produce a warning if any input file includes another file more than +once. In previous versions of +.B makedepend +this was the default behavior; the default has been changed to better +match the behavior of the C compiler, which does not consider multiple +inclusion to be an error. This option is provided for backward +compatibility, and to aid in debugging problems related to multiple +inclusion. +.TP 5 +.B "\-\^\- options \-\^\-" +If +.B makedepend +encounters a double hyphen (\-\^\-) in the argument list, +then any unrecognized argument following it +will be silently ignored; a second double hyphen terminates this +special treatment. +In this way, +.B makedepend +can be made to safely ignore esoteric compiler arguments that might +normally be found in a CFLAGS +.B make +macro (see the +.B EXAMPLE +section above). +All options that +.B makedepend +recognizes and appear between the pair of double hyphens +are processed normally. +.SH ALGORITHM +The approach used in this program enables it to run an order of magnitude +faster than any other "dependency generator" I have ever seen. +Central to this performance are two assumptions: +that all files compiled by a single +makefile will be compiled with roughly the same +.I -I +and +.I -D +options; +and that most files in a single directory will include largely the +same files. +.PP +Given these assumptions, +.B makedepend +expects to be called once for each makefile, with +all source files that are maintained by the +makefile appearing on the command line. +It parses each source and include +file exactly once, maintaining an internal symbol table +for each. +Thus, the first file on the command line will take an amount of time +proportional to the amount of time that a normal C preprocessor takes. +But on subsequent files, if it encounter's an include file +that it has already parsed, it does not parse it again. +.PP +For example, +imagine you are compiling two files, +.I file1.c +and +.I file2.c, +they each include the header file +.I header.h, +and the file +.I header.h +in turn includes the files +.I def1.h +and +.I def2.h. +When you run the command +.sp + makedepend\0file1.c\0file2.c +.sp +.B makedepend +will parse +.I file1.c +and consequently, +.I header.h +and then +.I def1.h +and +.I def2.h. +It then decides that the dependencies for this file are +.sp + file1.o:\0header.h\0def1.h\0def2.h +.sp +But when the program parses +.I file2.c +and discovers that it, too, includes +.I header.h, +it does not parse the file, +but simply adds +.I header.h, +.I def1.h +and +.I def2.h +to the list of dependencies for +.I file2.o. +.SH "SEE ALSO" +cc(1), make(1) +.SH BUGS +.B makedepend +parses, but does not currently evaluate, the SVR4 +#predicate(token-list) preprocessor expression; +such expressions are simply assumed to be true. +This may cause the wrong +.I #include +directives to be evaluated. +.PP +Imagine you are parsing two files, +say +.I file1.c +and +.I file2.c, +each includes the file +.I def.h. +The list of files that +.I def.h +includes might truly be different when +.I def.h +is included by +.I file1.c +than when it is included by +.I file2.c. +But once +.B makedepend +arrives at a list of dependencies for a file, +it is cast in concrete. +.SH AUTHOR +Todd Brunhoff, Tektronix, Inc. and MIT Project Athena diff --git a/soltools/mkdepend/parse.c b/soltools/mkdepend/parse.c new file mode 100644 index 000000000..a25fd9cd2 --- /dev/null +++ b/soltools/mkdepend/parse.c @@ -0,0 +1,402 @@ +/* -*- Mode: C++; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 4 -*- */ +/* $XConsortium: parse.c,v 1.30 94/04/17 20:10:38 gildea Exp $ */ +/* + +Copyright (c) 1993, 1994 X Consortium + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
