This repository contained build scripts for building WebAssembly toolchain components (including LLVM, Binaryen, and Emscripten). Eventually it was only used for the “emscripten-releases” builders used to build binary distributions for EMSDK on top of Chromium's infrastructure. So, we have moved it a Chromium repository for ease of development. You can find it in the
src/ subdirectory of the emscripten-releases repository.
