Machine Dependent Reorganization Pass

[kernel_learner]

Hi All,

 Thanks to my earlier email on this list I have been
able to correct my approach and make speedy progress.
I have made some changes including moving the call to
MACHINE_DEPENDENT_REORG to after the call that does
the delay slot scheduling. This way the instructions
that MACHINE_DEPENDENT_REORG sees is pretty much the
final list.

I am writing a MACHINE_DEPENDENT_REORG pass for
OpenRISC Architecture. For the purposes of my code I
need to analyze whether or not two instructions next
to each other are dependent on each other or are
independent.  I am not sure if the the instruction
dependency information which might have been
previously computed is VALID at the point where the
MACHINE_DEPENDENT_REORG pass is called. 

I need to figure out how I can compute or use
dependecy information between instructions in this
final list. Anyone have any suggestions?

Thanks in Advance,
KL
