So it w= as "unusable" and "broken". Using your words, next time I would appreciate you= to test your commits properly. >From arm64 case, I'm afraid I mistaken the llvm implementation of libunwind with that from devel/libunwind. libunwind from this port will compiles itse= lf, but many dependent ports will not. It exposes gcc-specific macros (a local variable in a named register) that is not used when compiling the library itself, but used by other parties. Did this looks like a humor for you? Be honest, we are both people and we both have the right to make a mistake = from time to time. (and the truth is, as my age grows, "from time to time" gets shorter and shorter). I'm closing this bug. --=20 You are receiving this mail because: You are on the CC list for the bug.=
