--- Comment #5 from torvald at gcc dot gnu.org 2011-11-09 12:28:28 UTC --- The weak alias issue has been resolved in rev 181182. The TLS thingy in 181163. Regarding the vector loads/stores and your assembler not knowing about .cfi, I don't know. Perhaps we just disable TM on Darwin, or can you provide a patch?
