Thanks. If you are interesting in RA whose code is available, you could also look at Fred Chow's RA code in Pathscale compiler. > Did you get a chance to look at the below patch. > The elements of allocno_hard_regs_subnode_index are setup in function > setup_allocno_hard_regs_subnode_index where elements representing subnodes of > a node > are nonegative.

I believe your patch is doing a right thing. It should be committed but I'd rather wait for stage1 start which probably will happen in 2-3 weeks. I'll commit your patch right after stage1 start. If I don't do this at this time, please ping me again, Zhouyi.
