[LLVMdev] About Code coverage Algorithms.

[Umesh Kalappa]

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
