Description
The ETH Research COmpiler (ERCO) is a research Java byte-code to
native compiler that is used in several projects in our group as for
teaching in advanced compiler classes.
We translate the Java bytecode
to an internal representation in static single assignment
form on which we perform several analyses and
some optimizations.
The backend generates native object file for the
Intel IA-32 platform
which are then linked to the Java runtime system provided by the
GCJ project.

Install & configure
Requirements
To be able to use ERCO and the programs compiled with ERCO you will need:
- A machine with an Intel IA-32 (x86) processor
- Linux
-
A Java compiler and virtual machine (as
Sun's JDK). Support for
JDK 1.4.0 is not yet completed, if you want more information
take a look to our
bug tracking system.
-
The GNU Compiler for the Java Programming Language. At the moment ERCO
need version 2.96 (3.x is not supported).
You can download it here.
- A C compiler (as GCC)
Installation procedure
ERCO has not yet reached a stage suitable for a public release. This page is meant to
be useful for our students involved in the project. If you want more informatio
please contact Matteo Corti or
Christoph von Praun
- Download the ERCO package
- Extract the ERCO source tree
-
Run the
configure script to set up ERCO for your configuration
(configuration options).
This small howto describes how to build a fresh liberco.
CVS
How to get ERCO using CVS:
- set the
CVSROOT environment variable to :pserver:yourcvsusername@lst.inf.ethz.ch:/usr/local/cvsrep/erco
- check out the source tree:
cvs co erco
In addition you can also check out the erco_test and erco_doc trees with
some test programs and various documentation respectively.
