GCC ILP instruction scheduling?

[Yang Yang]

hi folks:
	I'm reading something on ILP and instruction scheduling,
	while instruction scheduling is done by hardware 
	in out-of-order machines, I'm thinking doing so first in
	software statically might introduce more opportunities 
	for the hardware to find independent instructions, because
	independent insts are already scheduled closer

	a slide at the IMPACT site shows that gcc has very low ILP 
	optimization. I'm not sure if this software/hardware combined
	approach would help.

	thanks

	Yang
