-Using BigIntegers and BigDecimal on Kaffe
-=========================================
-
-Author: Dalibor Topic <[EMAIL PROTECTED]>
-
-Implementations
----------------
-
- Kaffe comes with two implementations of java.math package. The default one,
- from GNU Classpath, is written in Java. It is available on all platforms.
-
- The other implementation uses GNU MP for the actual calculations on
- BigInteger. Using the very fast GNU MP library makes it much faster than the
- default implementation.
-
-Configuration
--------------
-
- When Kaffe's configure script detects the presence of GNU MP library, it
- automatically takes care of building kaffe with GNU MP support enabled.
-
- Support for GNU MP can be explicitely turned off using the --without-gmp
- configure script option.
-
-Usage
------
-
- Kaffe uses the pure java implementation by default. If you want to use the
- fast java.math implementation, you need to run kaffe with the
- -Xnative-big-math option.
-
-Performance
------------
-
- Running the NativeBigInteger benchmark from i2p [1] shows that kaffe on i686
- on GNU/Linux with jit3 and jthreads is about 4 times slower than JDK 1.4.2
- using the default, pure java implementation of java.math.
-
- Using the native implementation, the tables turn, and kaffe is 5 times faster
- than JDK 1.4.2.
-
-[1] I2P is available at http://www.i2p.net. The benchmark is in the
net.i2p.util
- package.

+PS2 Linux Kaffe Building FAQ
+============================
+
+This document applies to kaffe-1.1.4 (and also contains hints
+for building from CVS).
+
+FAQ.ps2linux Status
+===================
+
+Last updated 28-Jan-2005 by Patryk Laurent ([EMAIL PROTECTED])
+Original document 18-dec-2002 Dylan Schell ([EMAIL PROTECTED])
+
+
+Test Notes [not updated or confirmed on 28-Jan-2005]
+====================================================
+
+- kaffe in interpreter mode currently fails 5 regression tests related to
+ IEEE compliancy. ( See Notes )
+- kaffe in jit3 mode currently fails a 27 regression tests since the
+ jit is emitting 64 bit floating point instructions that are not supported
+ on the PS2. ( see Notes )
+
+Building kaffe on the PS2
+=========================
+
+1. Install jikes ( version 1.21 was tested ) on your PS2
+
+http://ibm.com/developerworks/opensource/jikes/
+
+Compiling jikes will take some time on the PS2 but building the
+kaffe runtime library with the supplied compiler is a bit of a problem.
+Even if you get it to work, it is a lot slower than compiling jikes)
+
+2. Untar kaffe. Edit kaffe's libraries/javalib/rebuildLib.in
+
+Add -target 1.2 to the VERBOSE variable to force jikes to generate
+class files compatible with kaffe.
+
+VERBOSE=-target 1.2
+
+3. Run configure to enable jikes and select the interpreter engine:
+./configure --enable-pure-java-math --with-jikes --with-engine=intrp
+
+IF YOU ARE BUILDING FROM CVS, you probably should add --without-kaffe-qt-awt
and --disable-native-awt (otherwise you will get gtk+-2.0 missing errors in the
configure step.)
+January 22, 2005 From CVS: ./configure --enable-pure-java-math --with-jikes
--witth-engine=intrp --without-kaffe-qt-awt --disable-native-awt
+
+Or if you don't need double precision floating point support, you can
+build the jit3 version:
+./configure --with-jikes
+
+(Remember to run make clean if you change between interpreter and jit!)
+
+4. Compile/install in the regular fashion.
+make
+sudo make install
+
+Notes about the PS2 Linux port
+==============================
+
+The ps2 port is a work in progress, it works with the following limitations:
+
+1. Some IEEE constructs are not supported by the FPU: NaN/+Inf/-Inf/+0.0/-0.0
+If the PS2 kernel is ever updated to include a FPU emulator to add these
missing constructs, then this port should pass all regression tests.
+(This goes for the interpreter as well as for the jit version)
+
+1. jit3 is functional but will cause problems when using double precision
floating point operations. This is because the PS2 lacks a double precsion FPU.
If, or when the linux kernel is updated with a FPU emulator (and a matching gcc
is installed) to make up for this problem, the port will have to be updated (
the PS2 specific patches in config/mips/o32-sysdepCallMethod.h can go away ).
+
+To make sure interpreter bugs don't interfere with building kaffe on the PS2
use jikes to compile the class library/tests. Some versions of jikes generate
incorrect class files or class files that are too new for kaffe to handle.
Using jikes 1.13 seems to work OK.
+
+The PS2 also lacks the MIPS II "LL" and "SC" instructions. This means locking
is somewhat slower. the MIPS II instructions are disabled in
config/mips/common.h
+
+The PS2 register set is also different from basic mips processors. This means
the FP_OFFSET is much larger ( general purpose registers are 128 bit wide for
special multimedia/vector processing instructions )
+
+Note that the changes in o32-sysdepCallMethod.h pass 64 bit floats in a pair
+of general purpose registers. This is the convention gcc uses on the PS2 (
+This might be the default for all mips systems that lack these registers, I
+don't know...)
+
+Files with PS2 specific changes
+===============================
+config/mips/o32-sysdepCallMethod.h ( work around lack of 64 bit FPU regs )
+config/mips/common.h ( set FP_OFFSET / disable MIPS II instructions )
+config/mips/linux/md.h ( FP_OFFSET=36 )

-Sound libraries
----------------
-
-You need at least one of these libraries if you want to use kaffe's
-Java Sound implementation, which has been merged in from the tritonus
-project. More information on sound support in kaffe is available in
-FAQ.sound.
-
-ALSA:
- The Advanced Linux Sound Architecture backend provides both
- sampled sound and MIDI functionality. You need to have ALSA
- installed first, which is available at:
- http://www.alsa-project.org/
-
-Esd:
- The Enlightened Sound Daemon provides sound playback
- functionality on many Unix implementations. It is available
- at:
- http://www.tux.org/~ricdude/EsounD.html
-
-Mathematical libraries
-----------------------
-
-If you want to use arbitrary precision numbers provided by the
-java.math package, you can install these libraries. If kaffe can not
-find them, it will automatically use a pure java implementation from
-GNU Classpath.
-
-GNU MP:
- libgmp is used in the native implementation of
- java.math.BigInteger. It is available at:
- http://www.swox.com/gmp/
-
-Cryptographical libraries
--------------------------
-
-If you want to use cryptographical hashing algorithms, you need to
-install these libraries.
-
-libmd:
- This library is included with FreeBSD and may be included with
- other operating systems. It supplies implementations of the MD2,
- MD4, and MD5 hashing algorithms. If this library is not found by
- configure, then SHA is the only hashing algorithm that will be
- available. It can be found at:
- http://www.penguin.cz/~mhi/libmd/
