I tried running benchmark tests on my StrongARM RISC OS 4.29 RiscPC tonight, but SuperFPEm failed to complete the tests. The benchmarks used were the portable and famous Linpack test (built for RISC OS using GCC) and the Whetstone section of the RISC OS native benchmark app SICK. SICK reported a floating point exception. I'll contact Mech about this as soon as I can.
If I get time again, I'll run simpler tests, such as calculating e using FP.
