(When compiling specifically for Opteron 6344 with GCC 12 (and nearby versions), I had trouble unless I added <code>-fno-expensive-optimizations</code>. It is some problem involving fused multiply-add instructions. The same problem occurs if you use the built-in <code>fma</code> function of GCC. Other projects have had similar difficulties.) |
