Subject: Move the stuff that fixes the size, orientation & fonts of graphs to
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=6178085cfd772f62c641234bec156240281e7cf4;p=oota-llvm.git

Move the stuff that fixes the size, orientation & fonts of graphs to
the debugging functions that call "dot". These fixed settings have
various problems: for example, the fixed size that is set in the graph
traits classes is not appropriate for turning the dot file into a PNG,
and if TrueType font rendering is being used, the 'Courier' TrueType font
may not be installed. It seems easy enough to specify these things on the
command line, anyhow.
