I have converted my raytrace program to use the virtual FPU device in OVCC.
It improves performance by around 50 times.
As I was no longer using any function (pow,sin,cos) from the standard mlib.l
library I removed it from the link and it links without any issue however
the floating point maths computations are all zero!!!
This seems strange. Why would I need to include a library that is no longer
referenced?
So if I use either of these two compile commands:
cc -A raytrace.c -l=/dd/lib/mlib.l -m=8k
or
cc -A raytrace.c -m=8k
Both compile and link without error however only the former produces correct
output.
