Sorry for the delayed response. I'm not personally familiar with -stop-after and -start-after. However, the gold-plugin will pass along any unrecognized options to the LLVM backend. So presumably a gold plugin user could specify them like -Wl,-plugin-opt,-start-after=pass-name.

I assume they are useful for debugging? Are they currently also supported for clang? E.g. clang -O2 -mllvm -start-after=pass-name ...?
