[PATCH] D29872: Do not legalize large add with addc/adde, introduce addcarry and do it with uaddo/addcarry

[Amaury SECHET via Phabricator via llvm-commits]

deadalnix updated this revision to Diff 96483.
deadalnix added a comment.

Add a FIXME on ADDC/SUBC to explain they are deprecated in favor of ADDCARRY and SUBCARRY and will be removed in the future.

Replaced several uses of auto with explicit types as per request.
