DFA Instruction Output for VLIW

[Dan Towner <dant at picochip dot com>]

Hi all,

I am using the DFA to schedule code for a VLIW. The assembly language
for the target has VLIW packets of the form:

insn1 | insn2 | insn3

At the moment, I can only get the scheduler to emit VLIW'd instructions
on successive lines. What is the easiest way to get the DFA scheduler to
generate instructions in a single line format, or alternatively,
generate a continuation on the end of each VLIW'ed line, but stopping
once it has reached the end of the VLIW packet:

insn1 \      
insn2 \
insn3

Furthermore, some common instructions such as add's or copy's have to
mark the EU to which they should be issued:

ADD.0 something | ADD.1 somethingElse

I think that I can solve this by using TARGET_SCHED_REORDER to set an
attribute for the instruction, marking the EU to which it should be
issued. Does this seem feasible?

Thanks, 

Dan.
