<siraben>it's just recursive descent should be able to handle all those <siraben>I found out that I can shave another 111s off the bootstrap if I use the second-to-last compiler in the blynn chain with no source changes <janus>siraben: when you work on hcc, do you use GHC until it works and then check to see if blynn matches? Or do you work exclusively in blynn? <siraben>janus: I work in ghc generally for iteration speed, but always checked with blynn (it's CI gated so I can't merge into master if it doesn't pass full faithful diverse double compilation) <siraben>Right now the concern is more performance and getting that up. I think over the weekend I will just fork blynn and adjust its behavior to my liking <janus>why is it important to have perforamnce? if the point of bootstrapping is to gain confidence, isn't it good enough if it is slow and simple? <siraben>janus: It won't be overly optimized to be fast, I just think it's possible to be fast and auditable at the same time <siraben>I like working with blynn stuff because everything passes through the VM eventually, and there are a finite set of combinators. The VM could even be implemented in M1 or some macro language <janus>sounds great. i will spend more time understanding blynn's prose and code <siraben>with some configure flags managed to get tcc to compile 17% faster (so we can get to self-hosting faster) <siraben>amd64 stage1 tcc binary: 461,681 → 367,552 bytes (−17.2%). HCC compiling tcc.c on the faithful M2-Planet path: 5:46 → 4:46 (−17.3%). <siraben>hcc's time is mostly spent in I/O, not sure how to address this, haskell isn't exactly the fastest language for I/O heh <siraben>oh but then I have to do some small asm files anyway... <matrix_bridge><cosinusoidally> I know nothing about Haskell, but surely buffered io is the solution? I've definitely seen massive performance improvements in my bootstrapping code by using io buffering. <siraben>cosinussoidally: yeah I added various buffered writes to the FFI to bring it down <siraben>ACTION starts disabling a bunch of stuff in tcc for initial bootstrapping <roconnor>siraben: how did you add buffered writes? <roconnor>I'm thinking of writing my own blynn-style compiler. Likely aiming for the same source language though.
