The total compile time of the toolchain is impacted little since now we have to build these extra packages but they are relatively small. However I think I need to measure the total compile time as well to make sure it does not impact gcc's compile time performance. My intention was to provide the capability in the compiler/SDK so that someone can utilize it if he/she wants. e.g. gnuradio folks I am sure will benefit from it > > Whilst this looks nice for experimentation, are there documented > benefits for a system compiled with this? > I did not find official documented advantages but there has been several posts where improvement in performance has been observed. There was a lengthy thread I found on gentoo where they saw total system performance boost when they enabled graphite. I think it is more of RFC so people can try it out and then we can weigh in benefits of it in OE context. _______________________________________________ Openembedded-core mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
