2002 Paper 3 Question 1
Compiler Construction
(a) Give a diagram showing the phases of a typical compilation system for a
language like C which produces a directly executable fully-linked binary file
as output. For each phase, describe in a paragraph what it does (mentioning
possible implementation techniques) and give a brief overview of the datastructures used for its input and output indicating whether they would
normally reside in a file or in memory. (Do not specify details of any files
used to automate the writing of any of the above phases.) [16 marks]
(b) Indicate how a typical Java implementation might differ and explain what is
meant by just-in-time compilation. [4 marks]
