[TCWG CI] 403.gcc failed to run after working-3971-g5f7f484ee54e: [AArch64] Add GPR rr instructions to isAssociativeAndCommutative

Hi David, Our CI flagged your commit; it seems it miscompiles 403.gcc from SPEC CPU2006 at -O3 -flto for aarch64-linux-gnu. Would you please investigate? Let me know if you need any assistance in reproducing this. Thanks! === After working-3971-g5f7f484ee54e commit 5f7f484ee54ebbf702ee4c5fe9

Hi David, Also happens for -O2 -flto. Other affected configurations will be automatically added to [1]. [1] https://git.linaro.org/toolchain/ci/interesting-commits.git/tree/llvm/sha1/5f7f484ee54ebbf702ee4c5fe9852502dc237121/tcwg_bmk_llvm_tx1 -- Maxim Kuvyrkov https://www.linaro.org > On N

Hello. Thanks for the info. Just to check - this is a correctness problem? We run SPEC2006 here and I didn't see a problem with 403.gcc. The patch was reverted though, so something is certainly wrong with it! Do you have any details on how you run spec 2006, in order to reproduce it? Thanks Da
