The adjustment seems to have very little impact on optimizations. The only binary change with -O3 MultiSource/SPEC2000/SPEC2006 on X86 is in consumer-typeset and the size there actually decreases by -0.1%, with not significant changes in the stats. On its own, it is mildly positive in terms of compile-time, most likely due to LICM & DSE having to process slightly less instructions. It should also be unlikely that DSE/LICM make much new code dead. http://llvm-compile-time-tracker.com/compare.php?from=df63eedef64d715ce1f31843f7de9c11fe1e597f&to=e3bdfcf94a9eeae6e006d010464f0c1b3550577d&stat=instructions With DSE & MemorySSA, it gives some nice compile-time improvements, due to the fact that DSE can re-use the PDT from ADCE, if it does not make any changes: http://llvm-compile-time-tracker.com/compare.php?from=15fdd6cd7c24c745df1bb419e72ff66fd138aa7e&to=481f494515fc89cb7caea8d862e40f2c910dc994&stat=instructions Reviewed By: xbolva00 Differential Revision: https://reviews.llvm.org/D87322
