[01:45] <cfbolz> ah, right
[01:45] <stakkars> where? [yes, I'm sleeping :-]
[01:45] <pedronis> now we are 4.7 slower than CPython 2.4 on my office machine with count1
[01:45] <stakkars> what what what
[01:46] <pedronis> but 11.3 times slower with count2
[01:46] <stakkars> pffffhht

[01:47] <pedronis> http://codespeak.net/svn/user/pedronis/count2.py
[01:49] <stakkars> crazy. doing this in RPython with inlining is 5000 times faster.
[01:49] <cfbolz> what a deep and insightful observation
[01:50] <stakkars> it is:
[01:50] <pedronis> well, the point is really the baseline behavior of our interpreter, and indeed that our function call impl is too costly
[01:50] <pedronis> that RPython is incredibly faster is not really the point of the exercize
[01:51] <stakkars> it is about the huge gap between that and what we can do with the interpreter.

[22:32] <sabi> yeah, i'm having trouble seeing where that happens :)
[22:33] <xorAxAx> i dont think that rpython has a long long type :)
[22:33] <sabi> i guess i can try returning it as a pair of unsigned ints
[22:33] <xorAxAx> and the long routines are at applevel
[22:34] <xorAxAx> multiple return values? :-)
[22:34] Rhamphoryncus (n=rhamph@unaffiliated/rhamphoryncus) joined #pypy.
[22:34] <sabi> stop it, i'm already demoralized enough :)
[22:34] <sabi> well i could probably return a struct
[22:34] <xorAxAx> i am too hungry to motivate someone :)
[22:34] Action: sabi stares at lltyping code some more
[22:49] _hannes (n=yuuhu@i577B71E7.versanet.de) joined #pypy.
[22:53] <mwh> sabi: no, no support for that yet
[22:53] <mwh> unless you're on a platform where sizeof(long) == 8, of course :)
[22:57] <sabi> hah, no win64 for me :)
[22:57] <sabi> mwh: actually what i'm trying to do is port --with-tsc to pypy
[22:57] <mwh> oh, i see
[22:58] <mwh> well
[22:58] <mwh> you could have a baseline timestamp and return the difference from that
[22:58] <mwh> and just assume you won't overflow a long
[22:59] <sabi> yeah, that'd probably work fine
[22:59] <mwh> it doesn't increment that fast, i think
[22:59] <sabi> no, hopefully not
[23:01] arre (n=ac@c-51c6e055.1321-1-64736c11.cust.bredbandsbolaget.se) left irc: Remote closed the connection
[23:01] <sabi> i guess i'll do ll_tsc_reset() and ll_tsc_read() or something for the moment then.
[23:01] <sabi> or i guess i could have read reset.
[23:02] Action: sabi tries.

[23:02] <xorAxAx> 32 bit will overflow every 1.5 seconds
[23:02] <xorAxAx> simple arithmetics
[23:03] <mwh> uh
[23:03] <mwh> ppc here, i think?
[23:03] <xorAxAx> http://www.sandpile.org/post/msgs/20003444.htm
[23:04] <sabi> well, at least initially i won't be dealing with operations that take >1 second
[23:04] <sabi> eventually i will, but i'll deal with that problem when i get to it. :)
[23:04] <xorAxAx> %-)
[23:04] Action: sabi is going to be using it on x86 primarily.
[23:05] <mwh> oh, right
