[PATCH] D51396: [Constant Hoisting] Hoisting Constant GEP Expressions

[Z. Zheng via Phabricator via llvm-commits]

zzheng added a comment.

Unfortunately bitcast + gep + bitcast will only change the constant GEP expr from multi-dimension to single dimension, and it's still a constant pool entry after lowering.
