From 3519c4d6e08ea695658b961829d4a603acf8e28a Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Wed, 26 Aug 2020 12:15:55 -0700 Subject: Documentation: add minimum clang/llvm version Based on a vote at the LLVM BoF at Plumbers 2020, we decided to start small, supporting just one formal upstream release of LLVM for now. We can probably widen the support window of supported versions over time. Also, note that LLVM's release process is different than GCC's. GCC tends to have 1 major release per year while releasing minor updates to the past 3 major versions. LLVM tends to support one major release and one minor release every six months.
