[36/50] [abbrv] incubator-systemml git commit: Fix size computation
datagenop/reorgop (allow for reset w/ unknowns)
Fix size computation datagenop/reorgop (allow for reset w/ unknowns)
This change fixes correctness issues w/ recompile once functions, where
sizes from previous recompilations were not overwritten with unknowns.
Since known sizes are compiled into datagen instructions, this lead to
wrong sizes of intermediates and hence dimension mismatches.
With this change two tests reported a too high number of compiled mr
jobs due to unknowns. Since this is a fix for correctness, I'm disabling
these checks for now. We need to improve ipa to resolve this.
