Wait a second...
What other way to use these .dot files, but to feed them to the dot
program?
"If the gcc is used in this way"?
it modified by one of the gcc developers to be used that way.
This issue is with the dump-tree-dot function.
It used to be named dump-tree-graphviz !
Diego has tried to remove references to the origins
of this tool, but all I can say is that support GraphViz is much less
in line with FSF policy then by trying to replace it.
See the change logs:
2002-05-02
* tree-dump.c (dump_files): Rename -fdump-tree-graphviz to
-fdump-tree-dot.
2001-08-20
the code was first added.
So, I would say that proverbial right hand does not know what the left
hand is doing.
