Ray: If the tool chain generates ELF image, its ELF image can be converted to EFI image by Edk2 GenFw tool. Then, this tool chain can be used for EFI development.
So, I propose to make CLANGDWARF tool chain generate ELF image and EFI image both. It can support the usage of ELF image generation.

If so, the people can use this tool chain for EFI development with DWARF format debug symbol. In dll generation phase, CLANGDWARF still generates dll image, then copy dll image to elf image. In EFI generation phase, dll image will be converted to EFI image.

There are many blanks appending the line “+ "$(DLINK)" -o ${dst} $(DLINK_FLAGS) @$(STATIC_LIBRARY_FILES_LIST) “ 2. We need a toolchain dependency descirption in the BaseTools\Conf\tools_def.template. Below is the example for CLANGPDB. Please add one for the CLANGDWARF. # CLANGPDB -Linux, Windows, Mac- Requires: # Clang 9 or above from http://releases.llvm.org/ # Optional: # Required to compile nasm source: # nasm compiler from # NASM -- http://www.nasm.us/ # Required to build platforms or ACPI tables: # Intel(r) ACPI Compiler from # https://acpica.org/downloads 3. We could merge the CLANG38 and the CLANGDWARF toolchains together in the future.
