[PATCH] D109977: LLVM Driver Multicall tool

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Hope that someone familiar with CMake can take a look.

> As currently implemented llvm-driver contains dsymutil, llvm-ar, llvm-cxxfilt, llvm-objcopy, and clang (if clang is included in the build).

I think either (bundled clang+binary utilities) or (bundled lld+binary utilities) is fine.
Some folks are interested in PGO builds for clang and lld. Not bundling clang and lld together can make both optimized.
The performance of binary utilities likely does not matter that much, so bundling them with either clang or lld should be fine.

I have tried the latest diff but `-DLLVM_ENABLE_PROJECTS='clang;clang-tools-extra;flang;lldb;lld;compiler-rt;openmp;mlir;cross-project-tests' -DLLVM_TOOL_LLVM_DRIVER_BUILD=on` gives me:
