[kaffe] Kaffe on XScale

[Jari Korva]

Hi,

I checked out a fresh copy from cvs yesterday, and the things started
rolling on my armv5b! Thanks for your help!!

I run regression tests and the following tests failed (most notably
floating point):

BadFloatTest.fail    DoubleComp.fail  DoubleNeg.fail    GCTest.fail
DateFormatTest.fail  DoubleCvt.fail   DoublePrint.fail
TestMessageFormat.fail

You can get more detailed results from:

I used following configuration:

# ./configure CFLAGS=-I/opt/cross/armv5b-linux/include
--prefix=/wrk/ipaq/u/jko/test --build=i686-linux
--host=armv5b-softfloat-linux --enable-xscale
--without-x --disable-alsatest --disable-esdtest --disable-sound
--enable-pure-java-math --with-jikes=/opt/local/bin/jikes
--without-classpath-gtk-awt --without-kaffe-qt-awt --without-kaffe-x-awt
--with-threads=unix-pthreads --with-engine=intrp --with-staticbin
--enable-debug --enable-xdebugging

And compiler:

# armv5b-softfloat-linux-gcc -v
