That one seemed to be fine, I could call the #new primitive as a function pointer. Then it only took me a small eternity to figure out that not machinery around the function pointer is broken, but the value of the pointer is the problem, leading to an ambiguity. WASM addresses start at 0, #primitiveNew got an int value of 220. This confused the interpreter, as it was looking at it as a quick primitive (value < 500 something), then even more confusing it as the value was below 256. That was the assertion that triggered. As I could not see an easier way to make function pointers and quick primitives distinguishable, I inserted a padding of 700 hundred useless methods before the primitives. It sure ain't pretty, but to my surprise it does the job. From then on it was just a good ol' whac'a'flag.</div></span></div></blockquote><div><br></div>Interesting. Assumptions about the implementation substrate and/or underlying platform are always present in any high-performance VM. I hope this assumption was sufficiently documented, but it looks like not. I like your solution. However, if primitiveFunctionPointer is signed on the WASM platform I would consider introducing a alternative, that being using negative numbers for the quick primitives.</div><div><br></div><div>As your work progresses you’re likely going to face more platform-specific issues, many of which will be within cCode:[inSmalltalk:] sends. You may need to add cCode:wasmCode:[inSmalltalk:] or some such.
