--- Comment #6 from Iain Sandoe <iains at gcc dot gnu.org> 2012-05-19 16:51:27 UTC --- Created attachment 27441 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27441 fix (bootstrapped *darwin9,10, lightly tested). .. well Darwin was already using TARGET_FOLD_BUILTIN which has now been over-ridden in i386.c, leading to the breakage of CFString. FWIW: since darwin has several targets - we try to keep common stuff in config/darwin* .. so it's always worth a quick check there, as well as in config/{i386,rs6000}/ The attached patch bootstrapped on *86*-darwin9/10, ppc-darwin9 - lightly tested ... needs checking on Darwin11.
