One of the runs disabled pc-relative addressing. One benchmark (imagick_r) was faster if PC-relative addressing was disabled. For this run I used the options: -DSPEC \ -DNDEBUG \ -I. \ -DSPEC_AUTO_SUPPRESS_OPENMP \ -g \ -save-temps=obj \ -Ofast \ -mcpu=power10 \ -mrecip \ -funroll-loops \ -msave-toc-indirect \ -mno-pcrel \ -fgnu89-inline \ -Wno-multichar \ -DSPEC_LP64 \ -frandom-seed=spec2017
