-* implementet all floating point instruction in x86.brg, we also need to check
+* 64bit integer mult with overflow checks + test bench
+* raise exceptions everywhere
+* exceptions: save/restore floating point state?
+* implement all floating point instruction in x86.brg, we also need to check
   the floating branch instruction - some of them seems to be wrong, we need to
   write better tests for that.
-* implement exceptions
-* correctly align value types on the stack and in arrays
-* enum types can have several base types (not only int32)
 * document the functions and variables in the JIT 
 * implement a register set for FP registers (just count register usage on x86)
 
+* Calling conventions:
+
+       Implement fast call
+
+* Overflow conversions:
+
+       Implement CONV_OVF_XXX (constant) variants that emit either
+       loads or exceptions (as we can always tell)
+               
+* use short jump opcodes where possible (for backward jumps), will give better
+  performance. 
+
+* Memory allocation of dynamic code.
+
+       The current interface to generate code and allocate the memory
+       for it is not very nice.
+
+       Use large buffers to allocate temporary code, rather than allocating
+       256 bytes every time, and hoping that it will be enough.
