Doesn't look bad, but I dislike the name change to _addr variants for functions that look up not just addresses. I think we should just fix up all the callers to pass in a mode. I'm also not sure we need a global cselib_record_autoinc flag - why not just do that always? Shouldn't we do something else when hashing PRE_MODIFY? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43494
