[LLVMdev] Pre-RA scheduler details
...sted in the two pre-RA instruction schedulers used in LLVM, list-hybrid and list-ilp. I've done some digging on the internet and played around with executing some test files using the two schedules. However, I'm still uncertain of the behaviors and heuristics used in each. For example, the XXXX_ls_rr_sort::isReady for hybrid includes a 3 cycle readydelay (seems arbitrary) whereas the ilp version readies all instructions once data dependencies are resolved. Additionally, the ilp_ls_rr_sort::operator() just calls BURRSort at the end after applying a bunch of heuristics to the queue beforehand. Readin...
