WebA first pass determines instruction lengths and addresses, while the second pass resolves final values and generates the object code (the machine language program). In the listing, the first pass shows how the assembler "sees" the source, while the second pass represents what the assembler actually resolves and lists this in a normalized format, which is close … WebAssembler is a program that. A. Places programs into memory and prepares then for execution. B. Automates the translation of assemble language into machine language. C. Accepts a program written in a high level language and produces an object program. D. Appears to execute a resource as if it were machine language.
