[PATCH] D69824: Extends the tblgen macro to allow mlir-tblgen to be installed

[Mehdi AMINI via Phabricator via llvm-commits]

mehdi_amini added a comment.

When you build/install clang for the host system, the clang-tblgen you would get is not necessarily compatible with the clang you intend to cross-compile. It is also a bit strange to me to expect that to build clang for a device you would need a toolchain that supply clang-tblgen.

Instead, I think the build scripts of clang when cross compiling should include the logic to build a clang-tblgen for the host as well and use it during the build process.
