Re: [cdt-dev] LLVM plug-in NPE

I think we share the same vision. For managed build, just extend GCC and remove/add the differences if needed. Also need basic auto-detection of the toolchain (just check PATH?). So I'm thinking of progressively removing stuff from the plugin to get there and see if there's anything valuable to keep in the process.

On Mac and Linux, it’s in the PATH. I’ll have to check, but MSYS2 might have clang, in which case it should use the same logic as mingw on MSYS2.

It was also added at a time when C++ on LLVM was young. Right now, clang is clearly the winner (over weird combinations with gcc). Also interesting is that clang is pretty much 100% compatible with gcc. For example, I simply added clang and clang++ as possible command names for the GCCToolChain in the new build system and it just works, including scanner discovery of built-ins.

So I’m not sure whether we really need LLVM support in CDT at all other than extend the exiting gcc tool definitions to handle clang as well.

The LLVM support was added as experimental and labelled as such when the user installs is.

The goal was to get this preliminary support in the hands of the community and stimulate

some interest to improve it.  It seems this is starting to happen :-)

any contribution is welcomed, I cannot comment on how much time any developer affords to spend on contributions, but LLVM support definitely deserves more attention.

as it is now, I consider it experimental, or even less, and I wonder how it got its way into the distribution.

if more progress is made, I can help with some testing on macOS.

Liviu
