Yes, i've seen your PRs about this. What's the status of your proposed patches? Would be nice if you could resubmit them for 4.5, IMHO.. > >I don't know why it almost feels like -Os people are second class >citizens in the Linux tribe. There are very few people who care or are willing to spend their time on Os, unfortunately. To quote Mark: I think this is a good idea. In general, I'm sure that we could better tune -Os, without adding much to the compiler, just by making these kinds of adjustments. So, I'm happy to see you doing that. </> (from http://thread.gmane.org/gmane.comp.gcc.patches/137674/focus=137696 where i proposed a two-liner to reduce all those jumps for switch statements. And yes, that patch was still not formally submitted but will have to wait for stage1 anyway). So i think that if we actively (given enough sparetime) try to improve Os that it would be well received. _______________________________________________ uClibc mailing list uClibc@uclibc.org http://lists.busybox.net/mailman/listinfo/uclibc
