site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com -mdynamic-no-pic is not supported for x86_64 (it is silently ignored), which is why you don't get an error. Performance gains are probably illusory, and you would get it without -mdynamic-no-pic. Under i386 you are attempting to link -mdynamic-no-pic code into a shared library, which is not supported. Don't do that. Shantonu Sen ssen@apple.com Sent from my Mac Pro On Dec 11, 2009, at 9:29 AM, Joel Reymont wrote:

The reason I want to use -mdynamic-no-pic is that it seems to give Firefox a large performance boost on Snow Leopard when compiled mostly statically and for x86-64.

Thanks, Joel
