[PATCH] D58521: [DAGCombiner] allow truncation of binops after legalization if desirable

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa added a comment.

I tried this patch on SystemZ / SPEC, and as before this seems to have a relatively very minor impact on the number of files changed (7), and on the performance (seemingly unaffected).

I think the SystemZ test looks good, but I leave the final approval to Uli as usual.
