turning on -fno-inline-functions-called-once
A while back, I believe back during the last FUDCon in Raleigh I talked with kylem and davej about turning off the "inline-functions-called-once" which inlines functions that are only called once. Turning off this optimization would allow SystemTap to work much better, especially in the NFS code... Kyle/Dave (or anybody else) remember if anything came out from that conversation? Is there any reason we should not remove this optimization? steved. ___ Fedora-kernel-list mailing list Fedora-kernel-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-kernel-list

I forgot all about that conversation. > Is there any reason we should not remove this optimization? I'd be really surprised if it's actually even measurable on modern CPUs.
