In-line Compilation

In-line or open compilation refers to compile-time expansion of a subprogram, with substitution of arguments, in-line at the point of each call.

Advantages:

• Eliminates overhead of procedure call

• Can eliminate method lookup in an object-oriented system

• Can expose opportunities for optimization across the procedure call, especially with OOP: more specific types become exposed.

• Relative saving is high for small procedures

Disadvantages:

• May increase code size
