The cppcheck --dump function generates a large dump file.

I use cppcheck dump function to generate dump file and find that some of dump file has a huge file size, so I want to ask that if it could be optimized.
I tested "nr_polar_kronecker_power_matrices.c" file from "https://gitlab.eurecom.fr/oai/openairinterface5g/-/tree/develop" project, and got a huge file size(1.12GB), please see the attachment png file.

what command did you use? is there several preprocessor configurations?
it is expected that the dump file is much larger than the source file that can't be avoided.
but well the dump file format was not designed to minimise disk usage. technically it could certainly be minimised. but I want to keep it easy to read and parse also. For instance, it is xml-based and that is not very optimal for disk usage but it's easy to use.

My command is :
cppcheck -f --language=c++ --dump source_file
thanks~

if you have a problem with file source I would suggest that you check a proper compile configuration. Can you generate a compile_commands.json file in any way? Do you use Make/CMake/..?
If you generate that you can use --project=compile_commands.json and then the dump files should be a lot smaller.
