-Instructions classification:
-FP : add, sub, mul, sdiv, copy, par, arg
-Maybe : and, or, xor, cmp(6)
-Non FP: 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. bcast
- - Convert fp to/from int. ftosi sitof (only signed at first, truncation)
- - Convert single to/from double fconv
-
-Summary:
- Add bcast, ftosi sitof, fconv
- Add a 'floating point' bit to instructions
- Conversions from/to unsigned types are hard!
- I need to find a reference for that.
-
-Roadmap in isel.
- Make sure all floating point immediates are accessed
- through a memory load. The load can be fused in some
- instructions (add, sub, mul, div). This should be
- handled similarly to the large integer constants.
- Note: contrary to large constants, the transformation
- also needs to be run on phi nodes!
-
- Complete ABI implementation, we should only need the
- movsd instruction to transfer between sse registers and
- memory.
