2024 EuroLLVM - Faster Compilation with GlobalISel: Skipping LLVM-IR

2024 European LLVM Developers' Meeting https://llvm.org/devmtg/2024-04/ ------ Faster Compilation with GlobalISel: Skipping LLVM-IR Speaker: ------ Slides: https://llvm.org/devmtg/2024-04/slide... ----- In a GlobalISel-based back-end, LLVM-IR is first translated to generic Machine IR (gMIR), which is then selected into target instructions. Instead of generating LLVM-IR, we emit gMIR directly and skip the first part of the code generation pipeline. For our application, this improved compile-times by ~20%. In this talk, we present how to work with gMIR, show how common IR constructs are lowered for GlobalISel, and discuss the performance of LLVM's instruction selectors. ----- Videos Edited by Bash Films: http://www.BashFilms.com
