---help---
Enable GCOV support for code coverage analysis.
After turning on this option, code coverage can be analyzed.
If this option is enabled, image size and performance will be
significantly reduced. Before use, you need to add the
"-fprofile-instr-generate -fcoverage-mapping" compilation parameters
to the file to be analyzed.
