Left shift

The shl instructions, short for shift-left, are used for performing a bitwise left-shift, similar to the << operator in other languages.

Try it


;; load two numbers onto the stack
i32.const 7   ;; 00000111
i32.const 1   ;; left shift one spot

;; perform a bitwise left-shift

;; the top item on the stack will now be 14 (00001110)
Instruction Binary opcode
i32.shl 0x74
i64.shl 0x86
