Interestingly enough, if I run either an interpretive kaffe 1.0.7
plus my MIPS patches, or an interpretive MIPS build of the
current kaffe.org CVS sources on a little-endian MIPS/Linux box
(a MIPS "Malta" board with a 5Kc processor on it), I get::
[EMAIL PROTECTED] BUGS]$ javac Test.java
[EMAIL PROTECTED] BUGS]$ ls
Hello.class Hello.java Test.class Test.java
[EMAIL PROTECTED] BUGS]$ java Test
9.999999
x>pf: 9.999999 9.0
x pe pf =9.0 7.0 9.0
which looks to me to be your "correct" result.
So the problem may be unique to x86 platforms, and if so,
that vastly reduces the number of places one needs to look
for the problem. It may be an x86 JIT bug, for example.
Could someone run the test on an interpretive-only x86
kaffe?
