--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-02-02 16:06:05 UTC --- > clang seems to support -mcmodel=large - at least at 3.1 - so any necessary > ld64/dyld support is available. The test compiles (using -c) with Apple clang version 1.7 (tags/Apple/clang-77) (based on LLVM 2.9svn) > This is not likely to get fixed in the short term (certainly not in stage 4) - > so we'll have to decide between XFAIL/tolerate the noise in the error logs. When XFAILed, this kind of bug disappears from the radar scopes and tends to rot forever (see pr10901) until it resurfaces in a nasty way. I'ld prefer to change the summary to something such as "large model is broken on *86*-apple-darwin*" to point to the real problem.
