Hi, we plans to make a super instruction for floor(expr1/expr2), which is an integer division (if both operands are integer numbers). We hope it would be benficial for embedded systems. I think the implementation would be similar to the JS apply() function: the fast case detects whether both operands are integer numbers and the function JSCell refers to the native floor function. The slow case would be the original SF byte code (the fast case has a jump to the end of the slow case).
Do other ports interested in such super instruction? Where would be easier to detect these kind of expressions: in AST level or in SF byte code level (as a peephole optimization)?
