llvm-14

[pin <voidpin%protonmail.com@localhost>]

Hi all,

I've been trying to update llvm to 14.0.6 with help from @wiz and all relevant package updates have been pushed to wip.

The following build fine,
lang/llvm
lang/libunwind
lang/libcxxabi
lang/libcxx
lang/clang
devel/include-what-you-use
devel/lld
devel/polly
lang/clang-tools-extra
parallel/openmp

Although lang/libcxx needs LLVM_UNWINDER=OFF, it used to be ON but, now fails with

CMake Warning at benchmarks/CMakeLists.txt:7 (message):
  The libc++ benchmarks are not available in a standalone build.  Please
  migrate to an official build as documented in
  https://libcxx.llvm.org/BuildingLibcxx.html.


-- ABI list file not generated for configuration x86_64-unknown-netbsd9.99.99.libcxxabi.v1.stable.exceptions.no_new_in_libcxx, `check-cxx-abilist` will not be available.
-- Configuring done
CMake Error at src/CMakeLists.txt:307 (add_dependencies):
  The dependency target "unwind" of target "cxx_static" does not exist.


-- Generating done
CMake Generate step failed.  Build files cannot be regenerated correctly.
*** Error code 1

Stop.

I can't seem to build these two,
lang/compiler-rt
devel/lldb

Please find the errors on the TODO files in wip for the respective packages.

As is, I don't seem to be able to take this any further :(
Anyone knows how to fix these issues?

Thanks!
