Subject: [PATCH] Revert "llvmPackages.tblgen: add missing lldb-tblgen"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Breaks Darwin bootstrap:

    CMake Error at /tmp/nix-build-llvm-tblgen-19.1.7.drv-0/llvm-tblgen-src-19.1.7/lldb/test/CMakeLists.txt:197 (message):
      LLDB test suite requires libc++, but it is currently disabled.  Please add
      `libcxx` to `LLVM_ENABLE_RUNTIMES` or disable tests via
      `LLDB_INCLUDE_TESTS=OFF`.

It’s probably not too hard to fix but I don’t really understand the
details of this derivation and it’s blocking Darwin `stdenv` builds
with a few days to go until the next cycle, so reverting for now.

This reverts commit d175d8a4c55ce11c61e70f6d0d0458e7801441c8.
