Abstract:

A system and method tests computer software using tracking bits in branch instructions to track portions of the software that have been tested. The tracking bits are bits of a branch programming instruction and may be repurposed hint bits used in the prior art to control pre-fetch of instructions. A branch tracking unit sets bits in a branch instruction of an application or program being tested. The branch tracing unit sets a first bit if a branch is taken and sets a second tracking bit if the branch is not taken. The modified program instructions can be analyzed after running the test inputs to determine if any branches in the software have not been exercised by the test inputs.
