2020 LLVM Developers’ Meeting: K. Li & T. Islam “Towards a representation of arbitrary alias ...”

https://llvm.org/devmtg/2020-09/ — Towards a representation of arbitrary alias graph in LLVM IR for Fortran code - Kelvin Li & Tarique Islam Slides: https://llvm.org/devmtg/2020-09/slide... _representation.pdf — LLVM compiler infrastructure becomes a popular choice for building compiler in the areas from research community to industry. The infrastructure can support different high level languages including Fortran. Our work focuses on utilizing the LLVM infrastructure for Fortran programs. We are particularly interested in developing an IR representation for precise alias information generated by IBM XL Fortran frontend. We use the ScopedAlias and NoAlias metadata to annotate on the load, store, and call opcodes. The compile time and run time performances are compared with no alias information emitted from the frontend. The results and the challenges of this approach will be presented and discussed in the talk. —
