**Objectives**

Enhance PyPy to dynamically adapt to its run-time environment and
to the characteristics of the running program.  Dramatically 
increase speed by enabling Just-In-Time compilation and
specialization.  Address multiple processor architectures.

**Description of work**

**Task 1**

Apply and enhance techniques from the Psyco project.  Promote parts
of the static translator to be used for run-time specialization.

**Task 2**

Design and implement a back-end component for dynamically emitting
machine code for multiple processor architectures.  Enable dynamic
foreign function calls.

**Task 3**

Research optimisation heuristics for the Just-In-Time compiler.
Coordinate with WP06_.

**Deliverables**

- D08.1 A processor back-end supporting Intel(tm) i386 and PowerPC
- D08.2 A Just-In-Time compiler for PyPy

**Milestones and Expected Result**

- M3 High performance PyPy, together with WP07_. Outperform the
  state-of-the art (Psyco, Stackless).
