Summary: When I initially introduced -pass-remarks, I thought it would be a neat idea to make it additive. So, if one used it as: $ llc -pass-remarks=inliner --pass-remarks=loop.* the compiler would build the regular expression '(inliner)|(loop.*)'. The more I think about it, the more I regret it. This is not how other flags work. The standard semantics are right-to-left overrides. This is how clang interprets -Rpass. And I think the two should be compatible in this respect.
