[llvm-dev] How to get started with instruction scheduling? Advice needed.
Hi Phil, > I've been watching this presentation from a 2014 LLVM dev meeting Thanks for your sharing! I am reviewing: * The chapter 10 (Instruction Level Parallelism) and chapter 11 (Optimizing for Parallelism and Locality) of Compiler Principle[1] * Adding and Optimizing a Subtarget for MIScheduler[2] by Dave Estes * Scheduler for in-order processors - what's present and what's missing in LLVM[3] by Javed Absar * Writing Great Machine Schedulers[4] by Javed Absar and Florian Hahn Hi Alex, Please leading me to implement Machine scheduling model for at least one core (e.g. Rocket, PULP)[5] Rocket - RV64G - "in-order", single-issue applicaEon core, BOOM - RV64G - "out-of-order", superscalar applicaEon core[6] So what about PULP? is it in-order or out-of-order? Hi LLVM developers, Welcome to review our work about porting GlobalISel to RISCV[7] and give us some suggestion, thanks a lot!
