Bug#572746: libm: sinf/cosf performance is awful on amd64
Hi, I could not say for sure the difference between sin and sinf (for example) on Suse but the performance ratio I had on 32 bits, stayed the same on 64 bits. This is why I was surprised to get impressive slowness when moving to debian :( Thanks for pointing out the Suse patch : as we only have Suse or Debian at work I could not do more comparisons. How about including patches from OpenSuse ? Is it possible as a quick workaround? Thanks for your help.

Bug#460637: LinuxThreads manual pages
clone 460637 -1 retitle 460637 manpages-dev: Port over whatever is useful from LinuxThreads pages severity 460637 wishlist reassign 460637 manpages-dev retitle -1 Please remove outdated LinuxThreads manpages forcemerge 572716 -1 severity -1 minor block -1 by 519781 thanks Jonathan Nieder wrote: Josef Spillner wrote: The man pages are LinuxThreads-specific, even though the default implementation of pthreads is NPTL nowadays. Some library calls such as pthread_mutexattr_setpshared are missing, and some of the limitations (such as using inter-process mutex locking), options and other peculiarities also differ. Unfortunately I think that the docs are outdated upstream as well Indeed, the LinuxThreads man pages are not even maintained upstream any more AFAICT. My suggestion would be to copy over any information and text that applies for NPTL to the man-pages project, and once the man-pages versions are deemed suitable (or maybe right away), get the Debian glibc-doc package to stop shipping these files and manpages-dev to start. So splitting the bug in two: - Since the LinuxThreads man pages tend to be nice though outdated, I will be working as time permits to copy what is still applicable to man-pages. mtk seems to be okay with this plan, which is nice. See [1] for details on how to help out. - The pages in man-pages are usable and maintained, and I think we should ship them. This requires coordination between the two packages. Actually, manpages-dev should be changed first (with Replaces: glibc-doc, this requires no action by the glibc maintainers).
