...we don't have such compatibility problem. I'd suggest we reject one-dash long options to avoid collision with short options. For example, * -lto-emit-obj can be read as -l to-emit-obj * -thinlto-cache-dir= means -t -h inlto-cache-dir= in GNU ld I created a patch https://reviews.llvm.org/D79371 to disallow some one-dash long options. These options are carefully chosen: I can't find anything depending on their one-dash forms. lld has a spell corrector for option names so a misspelled -lto-emit-obj can be identified quickly. Thoughts?
