Comment 65 for bug 1711337

Thank you for your effort! Could you please attach a patch against the firefox source tree for the changes you made, in regards to make it compile with clang?

If you ran out of memory during linking of libxul.so you could try to append '-Wl,--no-keep-memory -Wl,--reduce-memory-overheads' as ldflags, that's what the guys at gentoo are doing at least.
