Hi Chris:
I repeated the tests, but this time I used -mips1 instead of -mips32. I received
exactly the same results -- compiling with -O2 -mips1 -mtune=r5000 caused the
three-second computation time and nan value in the 'float' portion.
(1) I am sure these parts can run MIPS32 code. They are also capable of 64-bit
MIPS IV, but I'm currently using 32-bit Linux on them.
