--- Comment #7 from jbeulich at suse dot com --- Maybe what would help is a discussion in the context of the binutils patch, despite it already having been committed. As said there and earlier here, there may be reasons to adjust (back) some of what it did, but there needs to be a sufficiently consistent pattern behind that and at least RCL/RCR, according to whichever pattern, have to remain unsigned-only.
