Matthias Boehm resolved SYSTEMML-1555. -------------------------------------- Resolution: Done Assignee: Matthias Boehm > Decouple literal replacement from in-place recompilation > -------------------------------------------------------- > > Key: SYSTEMML-1555 > URL: https://issues.apache.org/jira/browse/SYSTEMML-1555 > Project: SystemML > Issue Type: Sub-task > Components: Compiler > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Fix For: SystemML 1.0 > > > The current literal replacement framework contains basic scalar literal > replacement as well as the replacement of small matrix operations with their > literal results. If this framework is invoked with temporary matrix objects > created during size propagation any matrix operation would obviously fail. So > far, this created no problems because literal replacement was tied to > recompilations that are not in-place, i.e., recompilations that create a deep > copy of the hop dag, which in turn only happens for single-dag recompilations. > This task aims to decouple the literal replacement from in-place > recompilations in order to increase the literal replacement potential and > allow for a more flexible use of this literal replacement framework. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
