It means that the CC result can be usedinstead of a compare with 0, but only if the instruction has the 'nsw' flagset.This patch also adds the improvements of conversion to logical instructionsand the analyzing of add with immediates, to be able to eliminate morecompares.Review: Ulrich Weigandhttps://reviews.llvm.org/D66868 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/SystemZ/int-cmp-56.ll Tue, 17 Dec 2019 18:14:34 +0000 Jonas Paulsson <paulsson@linux.vnet.ibm.com>
