@nik here's an unusual but real-world example that triggers this.
https://github.com/google/highway compiles the same source multiple times (with 
different macros set) for generating code for multiple SIMD instruction sets.
The main source file sets a macro to its filename and includes a 
"foreach_target.h" which includes the file identified by that macro.

I understand this is complicated for analysis, so foreach_target.h does nothing 
if it detects that an IDE/analyzer are parsing. This relies on predefined 
macros such as
__CDT_PARSER__ __INTELLISENSE__ Q_CREATOR_RUN. Is there such a macro for clangd?


Repository:
  rC Clang
