It would also be a great opportunity for us to get feedback from the community about this. We have a non-interlocked processor which relies on the post ra scheduler to emit cycle-accurate bundles (valid bundles without incurring in structural hazards). The construction of bundles outside the scope of post RA scheduling will require structural hazard information to work properly for processors without pipeli...

...ove the design. Here's what you can expect in the MachineScheduler: 1. Precise register pressure tracking with back off. I'm in the process of checking in the pieces for this. It should be usable sometime in the next couple of weeks. 2. Division of the target-defined resources into "interlocked" vs. "buffered". The HazardChecker will continue to handle the interlocks for the resources that the hardware handles in order. Buffered resources, which the hardware can handle out of order. These will be considered separately for scheduling priority. We will also make a distincti...

...sed most of the postRA list scheduler code and the resource priority queue. Every time it needs to move forward, either because of a res hazard (HazardRec) or an invalid combination of instructions in the current packet (DFA), it closes the current bundle and advances to the next cycle. The non-interlocked nature of our processor forces the bundling logic to live with the scheduling logic. We cannot build bundles without the scoreboard. I also tried to build bundles as a preRA pass in order to reduce the register pressure (so the RA will take full advantage of the vliw architecture). I've...

Hey Everyone, I'd like to begin a project to rework the scheduler to address some problems we've discovered on this end. The goal is to get a more configurable/flexible scheduler while simplifying maintenance by separating policy from implementation to get independent and interchangeable parts. This is going to be challenging because we are still stuck on LLVM 2.9. We will be upgrading

Hi, I am working on developing a professional Marketing Materials for my systems. I plan on using a very good(expensive) company to do that so splitting the costs with several people would be nice.

Hi Martin, > The CPU that I am targeting is VLIW with no hardware interlocking (the next instruction does not wait for the previous to complete). This leads to fairly complex scheduling, but can be generally accommodated well in LLVM. Thanks for sharing your usecase about instruction scheduling, I am learning Instruction Selector by reading ARM and AMDGPU target'...
