I'm new to this community so first of all, Hi everyone!
I am a member of the Fortran Team at Arm and would like to draw your attention to the RFC that our team has sent today to llvm-dev/cfe-dev/flang-dev: http://lists.llvm.org/pipermail/llvm-dev/2020-June/141994.html
TL;DR We would like to move the bits of Clang that could be re-used by other frontends to LLVM. Is this something that Rust could benefit from? Would anyone like to get involved? Your input (either here or, preferably, on llvm-dev) would be much appreciated!
Thank you, -Andrzej
