About

The CLANGDWARF toolchain currently supports building for IA32, X64, ARM and AARCH64.

Due to the fact that it uses both Clang and the LLVM linker LLD, CLANGDWARF can be used on any host architecture to build all of these target architectures without the need to install cross compilers or linkers. This means the threshold for doing cross-architecture test builds and even test runs is lower for contributors than when using GCC based toolchain configurations..

Given that Clang and LLD already implement support for RISC-V target, let's add it to the CLANGDWARF toolchain configuration as well.

Project Scope and Timelines

Primarily, changes to BaseTools/Conf/tools_def.template in edk2 to support CLANGDWARF toolchain. Fix any issues blocking the build and test.

Changes slated for 2H 2023.
