Hello Martin,
The issue is that I want to count the coverage of "true/false" branches taken
in sanitizer's if conditions..
I see. Well, you may abuse a bit the existing:
-fsanitize-coverage=trace-pc
Enable coverage-guided fuzzing code instrumentation. Inserts a call to
"__sanitizer_cov_trace_pc" into every basic block.
And put corresponding builtins to the true/false branches in the instrumented
code.

Hello.
Right now, coverage information reports line execution of statements that
are present in the original source code.
Can you make a mapping of the instrumented code to statements that are
present
in the original source code?
