For next release
^^^^^^^^^^^^^^^^
- conv.any2uword doesn't accept uppercase hex letters
- see if we can let for loops skip the loop if end<start, without adding a lot of code size/duplicating the loop condition
this is documented behiavor to now loop around but it's too easy to forget about
this is documented behavior to now loop around but it's too easy to forget about
Lot of work because of so many special cases in ForLoopsAsmgen.....
How is it for the vm target? -> just 2 special cases in CodeGen.
