Chris Lattner 608fe88627 Added methods to make dealing with switches and branch instructions 
more tolerable.

Chris Lattner 8c2076b84e Make a new GenericBinaryInst class, instead of providing lots of silly 
little classes.

Chris Lattner 642a3063da Add a new slew of functions to allow dynamic_cast<> like operation for 
upcasting Value's to their subclasses.

Chris Lattner 0972270aaf Add extra forwarding accessor methods so that getMethodList(), getBasicBlocks() 
and getInstList() are obsolete... except for when modifying those lists.  This
makes code much more succinct and to the point.

Chris Lattner 31e23cdeb4 Renamed get.*Operator to create seeing that it would have to be qualified 
with the classname anyways.

Chris Lattner c3a6f546de A silly stupid test of the loop depth calculator was added. REMOVE in the 
future.

Chris Lattner ed59025460 IntervalPartition: recode to use IntervalIterator to do all the work 
LoopDepth.cpp: new file that calculates the depth of a loop, using
IntervalPartitions.

llvm-svn: 71
 2001-06-25 03:55:04 +00:00
Chris Lattner 554c161f1f Add a helper function bind_obj 
llvm-svn: 70
 2001-06-25 03:54:32 +00:00
Chris Lattner 3fe4504c28 Big changes. Interval*.h is now more or less finalized. IntervalPartition 
is recoded to use IntervalIterators.  IntervalIterators can now maintain
their own memory or let an external entity do it.

Loop depth is a new user of IntervalPartition for calculating the loop
nesting depth of a basic block

TODO: add IntervalPartition capability to split intervals between the looping
portion and the "tail" portion.
