Advantages and disadvatages of single and multi pass compiler?

Answer 1

A single-pass compiler reads the source code once and generates the object code in a single pass. This results in faster compilation times and efficient memory usage. However, it may not be able to handle forward references, leading to potential errors. On the other hand, a multi-pass compiler makes multiple passes over the source code, allowing for more complex optimizations and better error handling. However, it requires more memory and may result in slower compilation times.

Answer 2

Single pass:

Adv:

More efficient than multi pass compilers in the compiler phase.

Smaller compilers than multi pass

Dis:

Produces less efficient programs.

Multi pass:

adv:

Can be useful when optimizing code.

more machine independent

Java like variable declaration - it doesn't need to be before the use of it, because Java require multi pass compilers.

Dis:

Slower at compile time

Answer 3

single pas compiler is simpler than multipass compiler
