--- Comment #21 from Rama Malladi <rvmallad at amazon dot com> --- I did another triage for perf loss on Graviton 2 processor (neoverse-n1) based instance and found this commit: `a9a4edf0e71bbac9f1b5dcecdcf9250111d16889` to be the reason. As I had indicated in my earlier reply, I was doing a triage of perf loss going from gcc-7 to gcc-10. The perf of 519.libm_r 1-copy run improved 1.08x with the revert of commit: `a9a4edf0e71bbac9f1b5dcecdcf9250111d16889` on gcc-mainline ( `2f1691be517fcdcabae9cd671ab511eb0e08b1d5`). I am guessing that we don't see it on LNT/ Altra CPUs. So, please look into this issue fix. Let me know if you have any queries. Thanks.
