| + | === Re-wiring pointers | ||
| + | Unfortunately the changes were far more in depth than I expected, and I had to spend an additional ten hours going over the code to fix pointers, the lexer, and everything in between. Oh, and yet more emitters I forgot needed to be changed. Even the REPL itself didn't print out the full return value. This makes me reconsider my choice to go with a 16 bit system. Should the SD-8516 have been 32 bit? Maybe, maybe not. In the end, it works. A 16 bit system can run a 32 bit c, no problem. I mean, look at Commodore BASIC 2.0. It used floats for ints. Steve Wozniak even made a Sweet-16 so that it could use 16 bit registers. We can do 32 bit in the languages. No problem. We are not going to get any practical advantage from going 32 bit internal since we're running on WASM which is 64 bit native anyways. See? We can have our cake and eat it too here. | ||
