drcov2lcov is an implementation of DynamoRIO's drcov2lcov in Rust.
Currently supported features:
| Feature | DynamoRIO's flag |
|-----------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------|
| Specify a single input file using -i or --input option | -input |
| Specify an output file to store line coverage information. Default: <current_directory>/coverage.info | -output |
| Filter specific modules from the drcov file. This allows generating line coverage for only the modules matching the given regular expression. Default: None | -mod_filter |
Unsupported features:
| Feature | DynamoRIO's flag |
|--------------------------------------------------------------------------------------------------------------------------|--------------------|
| Specify a directory from which all drcov.*.log files will be processed | -dir |
| Specify a file which contains a list of drcov files to process | -list |
| Specify a test function regular expression in order to generate test coverage information in the output file | -test_pattern |
| Filter out specific modules from line coverage collection | -mod_skip_filter |
| Filter specific source code paths from each module for line coverage collection | -src_filter |
| Filter out specific source code paths from each module for line coverage collection | -src_skip_filter |
| Reduce the set of drov files from the input to a smaller set of drcov files containing the same coverage information | -reduce_set |
| Replace a module path with another one before gathering debug info for that module | -pathmap |
Adding support for the above features is about 2 hours of work so these will be added in a weekend when I have some time.\
The main purpose of this tool however has been implemented, which is to generate line coverage from drcov files.\
Also, all drcov file version formats are supported (1-5).
In order to generate line coverage from a drcov file you can just run
bash
drcov2lcov --input <input_file>
This will generate a coverage.info to the current working directory containing the line coverage.\
If you want to save the line coverage to a different path/name you can run
bash
drcov2lcov --input <input_file> --output <output_file>
You can either clone this repository and run
bash
cargo build --release
if you want to build this project from source or install directly from crates.io by running
bash
cargo install drcov2lcov
