Hello, Happy to see so many test results from IOhannes.
The 'perfotest' patches were initially created for function profiling, to check if there are particularly time consuming instructions. To mention a funny example: I was happy to see that fabs() was translated to a single instruction ANDPS / ANDPD for xmm registers. But for the FPU it is a call. The same for isnan(). That's why PD_BIGORSMALL must still do a bitpattern check on aliased floats. For benchmarking original and double-ready Pd as a whole, I used two (fairly cool and elaborate) patches which were written in pure vanilla: - Chaosmonster1 from www.martin-brinkmann.de (10 instances or so) - Cave of Creation by Hamster, http://puredata.hurleur.com/sujet-5080-2.html Both works feature enough of the rewritten code to make them representative overall benchmarks. If double-ready Pd performs as well as original Pd with usual compiler settings, on all possible platforms, I would be satisfied. After all, the purpose of the whole thing was to get some more decimal places in our numbers, not to make Pd run faster.
