Abstract: Systems, methods, and computer program products to perform an operation comprising identifying a first commit of a plurality for a software project, a source code of the first commit executable in a first system architecture, determining, based on a set of tests run against a built source code of the first commit for the first and second system architectures, that the first commit is a latest working build for the architectures, computing a score for each commit in a first set of the plurality, identifying a second commit of the first set of commits based on the scores for each commit, building the source code of the second commit for execution on the second system architecture, and determining that the source code of the second commit did not build successfully for the second system architecture based on an error at a first line of the source code.

Abstract: Systems, methods, and computer program products to perform an operation comprising identifying a first commit of a plurality of commits for a software project, wherein a source code of the first commit is executable in a first system architecture, computing a score for each commit in a first set of the plurality of commits, wherein each score reflects a likelihood of success in porting the source code of the respective commit from the first system architecture to a second system architecture, wherein a version of each commit in the first set of commits is between a version of the first commit and a current version of the software project, identifying one or more of the first set of commits based on the scores for each commit, and building the source code of the one or more of the first set of commits for execution on the second system architecture.
