[PATCH] D103865: [SystemZ] Generate XC loop for memset 0 of variable length.

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa added a comment.

On spec, I see now 8869 exrl instructions, each with its own xc target instruction. I wonder if we should try to avoid duplicating target instructions. I see in some files hundreds of identical xc targets (worst case is 845 identical ones in one file: f510.parest_r/build/vectors.s !).  67 files have more than 20 identical xc targets...
