JC is a Java virtual machine implementation that converts class
|
|
files into C source files using the Soot Java bytecode analysis
|
|
framework, compiles them with GCC, and loads them using a built-in
|
|
ELF object file loader. JC utilizes the GNU Classpath class library
|
|
and provides a fairly complete Java runtime including sophisticated
|
|
optimizations to increase runtime performance. JC also includes a
|
|
bytecode interpreter, and supports execution in either or mix ed
|
|
modes.
|
|
|
|
Although JC has good interpreter performance, JC doesn't try to be
|
|
fast in every situation. Instead, JC focuses on this question: how
|
|
fast can we go if we know some or all of the class files ahead of
|
|
time? The answer is: very fast! Optimizations that are just too
|
|
complex and expensive to perform at runtime are instead performed
|
|
at code generation time. JC's code generator is written in Java,
|
|
using the powerful Soot bytecode analysis framework. When combined
|
|
with the proven power of GCC's C optimizer the results are impressive.
|
|
As an additional benefit, JC contains very little architecture-specific
|
|
code and is highly portable.
