Instructions classification:
FP : add, sub, mul, copy, par, arg
Maybe : and, or, xor, cmp(6)
Non FP: sdiv, udiv, srem, urem, store(4),
load(7), ext(7), alloc(5), parc, argc, call
15 bits for operations 32768
-1 bit for s,d 16384
New conversion instructions:
- Bitcast conversion between fp and ints. cast
- Convert fp to/from int. ftosi sitof (only signed at first, truncation)
- Convert single to/from double stod dtos
Summary:
Add cast, ftosi sitof, stod dtos
Add a 'floating point' bit to instructions
Conversions from/to unsigned types are hard!
I need to find a reference for that.
Problem with "cls" field: for comparisons, this field is
for the argument of the instruction, but, in the case of
Load (for example), it is about the result.
