void clang::clangd::CanonicalIncludes::addSystemHeadersMapping

(

const LangOptions &

Language

)

Adds mapping for system headers and some special symbols (e.g.

STL symbols in <iosfwd> need to be mapped individually). Approximately, the following system headers are handled:

• C++ standard library e.g. bits/basic_string.h$ -> <string>
• Posix library e.g. bits/pthreadtypes.h$ -> <pthread.h>
• Compiler extensions, e.g. include/avx512bwintrin.h$ -> <immintrin.h> The mapping is hardcoded and hand-maintained, so it might not cover all headers.
