Good day,

I am writing asm function with using circular buffers and 40 bit float.

I want this function to work correctly  with C/C++ code,including C/C++ interrupt handlers.

1). my asm function used i4,b4,m4,l4 register which are scratched registers due to compiler references.

Must I save their values?

2)

 

Which interrupt dispatchers  should I use?

Which pragma should I add to my project to save 40bit data?

With best regards

Alexander.
