...nts & reduce a portion of inttoptrs. After llvm.psub is used, when SPECrate 2017 is compiled with -O3, # of inttoptr decreases to ~13,500 (59%) and # of ptrtoint decreases to ~14,300 (45%). To see the performance change, I ran SPECrate 2017 (thread # = 1) with three versions of LLVM, which are r313797 (Sep 21, 2017), LLVM 6.0 official, and r348082 (Dec 2, 2018). Running r313797 shows that 505.mcf_r has consistent 2.0% speedup over 3 different machines (which are i3-6100, i5-6600, i7-7700). For LLVM 6.0 and r348082, there's neither consistent speedup nor slowdown, but the average speedup is n...
