[PATCH] D129734: [InstCombine] Canonicalize GEP of GEP by swapping constant-indexed GEP to the front

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

The example provided shows that there is a missing opportunity for CSE (of address computation of Vec[i]). The decision on GEP ordering should probably better be based on more general reassociation analysis for enabling more CSE/LICM.
