I think the cleanest solution would be a check before starting build to detect if X is available or not. (ideally configure or otherwise port Makefile) But if we are talking about PGO removal do we have some numbers how much speed you gain? I don't feel any differences on my machine and JS benchmarks are about the same. Mozilla ships his own Firefox binaries all without PGO so I'm not sure about the support of that optimizations.
Drawbacks: 1) 2 full compiler runs - build time about ~2.5x 2) requires X to actually run the binary and do some profiling 3) it tends to fail in some cases -- Bernhard Froehlich http://www.bluelife.at/ _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-gecko To unsubscribe, send any mail to "[email protected]"
