I don't think we can really make any assumptions about what instructions a 32-bit x86 processor has available. Who knows what wacky stuff VIA or someone like that will come up with? The best thing seems to be just to stick to "lock; addl $0,0(%%esp)" for 32-bit x86. We now have the infrastructure to support multiple builds of libraries and have ld.so select automatically at runtime but I'm not sure it's really worth it. - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
