you probably don't want the ~2% perf improvement below... but i figured i'd post it anyhow :) well... i do suggest the use of fabsf() rather than fabs() -- gcc doesn't seem smart enough to figure out fabs() when you ask it to compile "-mfpmath=sse". but the #else part uses properties of ieee-754 float layout which you may or may not be interested in (ab)using. basically

Hi, It looks like SimplifyLibCalls has a tendency to emit calls to libm functions without checking with TLI whether these calls are available. For example, PowOpt has this code: struct PowOpt : public UnsafeFPLibCallOptimization { PowOpt(bool UnsafeFPShrink) : UnsafeFPLibCallOptimization(UnsafeFPShrink) {} virtual Value *callOptimizer(Function *Callee, CallInst *CI, IRBuilder<> &B)

Using libvorbis (1.3.5) I wish to extract the raw vorbis packets.  I've built some simple code on the excellent libvorbis API overview on the xiph.org site, but the example relies on the ogg_packet struct for final output and input to decoder, and shows now examples on how to do without it. Taking a look at the vorbis_bitstream_flush() function, which in the overview is the last step before

In beta 3 (Windows, libvorbis-1.0beta3.zip, compiled using BCB), I get a runtime overflow on line 322 when encoding a simple pure tone (44100Hz, 96kbps, 128kbps, or 160kbps). Changing the float to a double avoids the problem. float val=decay[i]*decscale; float att=fabs(f[i]/val); /// floating point overflow ... Chris http://www.goldwave.com --- >8 ---- List archives:

Hi all, I'm quite new to Vorbis, so please excuse me if I'm writing complete nonsense (and, if possible, tell me where I'm wrong). While searching for optimization possibilities in lib/psy.c, I found the following piece of code in _vp_compute_mask(): if(p->vi->smoothp){ /* compute power^.5 of three neighboring bins to smooth for peaks that get split twixt

Dear R users, psy version 0.65 is on CRAN now. psy provides several methods used in psychometry (kappa, icc, cronbach, screeplot (with simulations), non linear mapping, etc.) A bug has been fixed in function wkappa (weighted kappa): in particular circumstances, the 2*2 table presented levels in an order different to what was suggested in the help file.

I'm running Psi-Ops in Ubuntu 8.04 with Wine 1.1.2. When I'm playing, whenever I spin around the character, it stops from the left or to the right and also looking up and down when I move the mouse to far up or down. This is really annoying when moving around and trying to throw things. Is there anyway to fix this? I tried changing Graphics settings in the Wine Configurations under Window

Hi, How can I define a new psi function in the rlm comand? In particular I would like to implement the case for \rho(u)=0.5*(u^2) and \psi(u)=u in order to assume normally distributed errors.
