Keno Fischer 1495c2d33b [ExecutionDepsFix] Don't revisit true dependencies ... If an instruction has a true dependency, it makes sense for to use that register for any undef read operands in the same instruction (we'll have to wait for that register to become available anyway). This logic was already implemented. However, the code would then still try to revisit that instruction and break the dependency (and always fail, since by definition a true dependency has to be live before the instruction). Avoid revisiting such instructions as a performance optimization. No functional change. Differential Revision: https://reviews.llvm.org/D30173 llvm-svn: 299467		2017-04-04 20:30:47 +00:00
