Maybe the problem is specific to EV6 and above? Well I did see some indication that -mieee breaks EV6 and above. They were old messages though so who knows what gcc does now. Why ever did Digital not just implement ieee floating point properly in the first place. :) I am still new to using an alpha, so not quite sure what gcc arguments do what yet. > Is another alpha developer willing to help?

Certainly the package as it is now builds fine with meth_emu enabled (loaded as module or built in) on an EV56 (PWD 433au), and the test fails without math_emu. Here is my /proc/cpuinfo in case you want to compare against the other EV56 that supposedly worked fine without math_emu: cpu : Alpha cpu model : EV56 cpu variation : 7 cpu revision : 0 cpu serial number : system type : Miata system variation : 0 system revision : 0 system serial number : cycle frequency [Hz] : 433149046 est. timer frequency [Hz] : 1024.00 page size [bytes] : 8192 phys. address bits : 40 max. addr. space # : 127 BogoMIPS : 858.04 kernel unaligned acc : 0 (pc=0,va=0) user unaligned acc : 0 (pc=0,va=0) platform string : Digital Personal WorkStation 433au cpus detected : 1 L1 Icache : 8K, 1-way, 32b line L1 Dcache : 8K, 1-way, 32b line L2 cache : 96K, 3-way, 64b line L3 cache : 2048K, 1-way, 64b line -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
