FPU

we assign op=OP_MDDS something to tell the hardware the current opcode and float64_add_next etc are used to compute the softvalues .. no calculations by hand

PLI

tf_putlongp() is a PLI function which puts a 64 int value to the current task or function

my_putlongp() is a helper function which takes in dest and value and stores it into that dest with some PLI function...

similarly for my_getlongp() and my_gettime()
