[PATCH] D155688: [PATCH] [llvm] [InstCombine] Canonicalise ADD+GEP

[Craig Topper via Phabricator via cfe-commits]

craig.topper added a comment.

After this patch, I'm seeing a lot of `invariant.gep` created by LICM. For example, in `LBM_performStreamCollide` in 470.lbm there are 65 of them. On RISC-V, these all get created in registers outside the loop and get spilled. Is ARM seeing anything like this or do you have more addressing modes that allow CodeGenPrepare to bring these back into the loop?
