Hi, I would like to experiment with modifications to the instruction flow during scheduling. One motivation for doing that is the combining of contiguous loads like was discussed here: http://gcc.gnu.org/ml/gcc/2010-12/msg00153.html
I've seen that the scheduler itself does some modifications to the intruction flow to introduce the speculative form of the instructions, but is it somehow prepared to modifications to the instructions from the target hooks (TARGET_SCHED_REORDER) ? If yes, what are the primitives that one should use to notify modifications? If no, what would it take to make that possible? Thanks, Fred
