...Thus, it is not known until the algorithm is done, which of the created induction variables are unused. FWIW I noticed that other optimizations (as seen in StandardPasses.h) are followed by -instcombine for cleanup. I thought requiring or suggesting running -instcombine after -osr would be SOP. FWIW2 our intent in creating OSR was not to replace LSR, just provide an alternative strength reduction optimization. > -Eli Brian

Strength reduction is sort of a special case; it runs extremely late because it interferes with other optimizations. > FWIW2 our intent in creating OSR was not to replace LSR, just provide an > alternative strength reduction optimization. Sure, but if it can't be used as an alternative to LSR, how would it be used? -Eli
