Hi All,
Good day for everyone .
We benchmarked the code coverage algorithms like
a)Optimal Edge Profiling (ftp://ftp.cs.wisc.edu/pub/techreports/1991/TR1031.pdf .) that are adopted by GCC and LLVM b)Dominator Leaf instrumentation(http://users.sdsc.edu/~mtikir/publications/papers/issta02.pdf) and i don't see the practical implementation of this.
Goal is to reduce the instrumentation point and when we benchmarked both algorithms .The number of blocks that are required to instrument is less in option-b over option-a.
Need some expert insights on this like why the option-b is not widely used over option-a.
Thank you ~Umesh
