# Global user-level clangd config (see clangd official docs)
CompileFlags:
  Add:
    - '-Wno-unknown-pragmas' # ignore GCC-specific pragmas
    - '-ferror-limit=0' # debug clangd failures without it stopping
  Remove:
    # For obvious reasons:
    - '-Werror'
    # Remove PCH includes as it triggers indirect GCC stdlib inclusion and clangd
    # doesn't like that, at all. Also related: #45
    - '-include'
    # Other gcc options clang doesn't recognize
    - '-mword-relocations'
    - '-fconcepts-diagnostics-depth=*'
