[LLVMdev] boost shared pointer & llvm

[Stefan Weigert]

hi,

thanks for your quick replies. -DBOOST_SP_USE_PTHREADS worked indeed. however, 
i didn't measure the performance but i would assume that the boost developers 
had a good reason for using assembler in this context. will llvm ever support 
inline assembly? is there anybody who is working on that?

thanks,
stefan.
