Hi, I have a model (let''s say User) and I would like to add any number of user-defined-settings to this Model. I created a UserSetting Model with user_id, key and value. I connected them with has_many. I know how to access these properties from a user but I would like some methods like user.hasProperty? / user.getProperty ... I think I know how to write these methods/finders myself but

Maybe MF.getProperties().hasProperty(MachineFunctionProperties::Property::NoVRegs))? ~Craig On Mon, Jan 15, 2018 at 12:07 PM, Martin J.

Hi LLVM Devs, I have some shared code that performs lowering operations that can occur before or after register allocation. When it is pre-RA I want to only use virtual registers for intermediate results, but post-RA I have to use only a very restricted set of physical registers. Code generation using the restricted set is not as efficient as it is when I can use virtual registers. At

Please don't rely on this for checking whether regalloc was run: You can have functions without vregs pre-RA[1]. We don't need or should track state such as pre/post-RA as part of the function. Instead it really is a property of where a pass was scheduled, so the pass should know and not the function. I'd recommend simply creating a pre-RA and a post-RA pass instead of scheduling the

Thanks Matthias, I have both a pre-RA and a post-RA scheduler, and I had thought that I could track “has RA happened?” by setting a flag in my pre-RA scheduler as it completes - my suspicion (which you have confirmed) was that “#vregs == 0” was not a safe assumption. What I cannot be sure of, is what passes execute after my pre-RA scheduler but before RA, and what passes execute after RA but
