Way to un-define symbols for a file while indexing? [message #1849165]

My current (inherited) project does some very complex things with the C preprocessor, including multiple passes, self-#includes with different #defines (different phases of code generation), X macros, you name it.

It would be very helpful to be able to remove or un-define specific symbol definitions when indexing specific files.

Is there a way to do that?

Thanks in advance!

Have a look at <https://gcc.gnu.org/onlinedocs/cpp/>, part 3.8

If you can, clean up the mess.
