--- Comment #1 from ptomsich at gcc dot gnu.org --- Created attachment 64026 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=64026&action=edit Combine trailing zeros patch A first shot, only tested on AArch64. In addition to the change to combine.cc, it required an extra split-definition in aarch64.md; final cleanup happens in late_combine2.
