Bill Currie	c57df8b5f3	Print all dag nodes in a dag. ... Dags can have multiple roots, so only recursing once could miss much of the dag.	2012-11-15 13:44:06 +09:00
Bill Currie	dbf1aa8f72	Attach dags to statement blocks. ... Now, if a dag is attached to a statement block, it will be included in the flowgraph with that statement block.	2012-11-15 13:44:06 +09:00
Bill Currie	24553867a4	Use dashed lines for attached identifiers in dags.	2012-11-15 13:44:06 +09:00
Bill Currie	d9354255a3	Avoid double-printing dag nodes.	2012-11-15 13:44:05 +09:00

Bill Currie	60108c688c	Change dags from binary to trinary. ... I'd forgotten some instructions take three inputs that can benefit from CSE.	2012-11-15 13:44:05 +09:00
Bill Currie	0fefeb73fe	Initial support for basic block dags. ... Currently, only dumping to dot, but that seems to be a very sensible place to start: debug support.	2012-11-15 13:44:05 +09:00
