23 * @author Martin Trapp, Christian Schaefer, Goetz Lindenmaier, Hubert Schmidt
26 * Dump routines for the ir graph and all type information.
28 * The dump format of most functions is vcg. This is a text based graph
29 * representation. Some use the original format,
30 * but most generate an extended format that is only read by some special
31 * versions of xvcg or by the comercialized version now calles aiSee.
32 * A test version of aiSee is available at
33 * http://www.absint.de/aisee/download/index.htm.
35 * We have developed an own advanced viewer called ycomp:
36 * http://www.info.uni-karlsruhe.de/software.php/id=6&lang=en
38 * Most routines use the name of the passed entity as the name of the
41 #ifndef FIRM_IR_IRDUMP_H
42 #define FIRM_IR_IRDUMP_H
49 * Symbolic names for the different dumping colors.
