Dear GCC developers, Emacs 29, to be released soon, will come with a built-in client for the LSP protocol. This allows to enhance important Emacs features, such as at-point documentation, on-the-fly diagnostic annotations, finding definitions and uses of program identifiers, enhanced completion of symbols and code, etc., based on capabilities of LSP servers.
The Emacs LSP client comes with support for many popular LSP servers OOTB and for all the programming languages supported by Emacs. However, all the available servers for C and C++ languages are based on Clang. AFAIU, this is because GCC does not yet have its own implementation of the LSP. I found this message posted to gcc-patches in 2017: https://gcc.gnu.org/legacy-ml/gcc-patches/2017-07/msg01448.html which described the initial implementation of LSP in GCC, but I seem to be unable to find out what happened with that since then. Are there plans for implementing the LSP in GCC? If so, which GCC version is expected to have this included? If there are no current plans for implementing LSP, I hope someone will work on that soon, given that Emacs can now use it, and because having a GCC-based LSP implementation will allow people to use their installed GCC as the basis for LSP features, instead of having to install yet another compiler. TIA
