Hello, i m scavenging the web for information regarding Kaffe's register allocation. So far, the loot is not that impressive. So here we go. I m looking for someone who is familiar with register allocation in the KaffeJit. Nothing fancy, i just need the broad perspective. If someone could fill in the blanks (and i apologize for my ignorance) : Kaffe does register allocation on basic blocks, ie at the beginning of a new basic block b, all allocation is flushed, and an allocation for b is computed. Furthermore, kaffe uses virtual registers, that are mapped on the machine registers. The content of a virtual register is a slot. Now, the register struct has a pointer to a SlotInfo struct, which i assume is the current content of this register. But each SlotData struct also has a pointer to subsequent Slotdata structs...what is the meaning of this? And what's the role of the sequence struct? So, that's pretty much what i'm looking for. If someone could please help me out? thanks in advance, pieter bellens

Hey I am profiling the kaffe vm using java but I would also like to use jython, does Kaffe support other languages or is built mainly with java in mind. If so can you tell what needs to be done to Kaffe inorder to make it compatible with another language such as jython. Thanks a million Alicia __ Do You Yahoo!?

Hi,
I have done JNI_CreateJVM through an independent test program which works
fine where as the the same call from my OJI Plugin
crashes inside JVM. I copied all .la and .so , .jar files in my class path.
Still it is giving the same error.
Can anybody tell the solution ? Is there any known limitations for Kaffe for
enabling it for mozilla ?
Regards...
Prasad

Turn on vmdebugging ('-vmdebug all'). Its probably failing to find a
.la file, or some of the basic system classes. You might have to
hardcode vmdebug since you don't have a command line(?). (Change
DEFAULT_DEBUG_MASK in kaffe/kaffevm/debug.c to DBG_ALL).
Also, you sent your message to '[EMAIL PROTECTED]', and I think
you meant to send it to '[EMAIL PROTECTED]'.

Just grab the "net installer" from one of the mirrors and run it to install gcc and gdb on your NT system. Download the installer. ftp://ftp.freesoftware.com/pub/sourceware/cygwin/latest/setup.exe Run it and then point it at a mirror like ftp://ftp.freesoftware.com/pub/sourceware/cygwin/latest ftp://ftp.sunsite.utk.edu/pub/cygwin/latest/ You should then be able to download and extract a tar ball of Kaffe. Then you just cd to the kaffe directory run ./configure ; make ; make install and it should build and install. I have not tested this myself so you may run into problems but that is how it "should" work. Mo Dejong Red Hat Inc.

dear sir, I am interested in porting kaffe on windows NT system. I have downloaded the source code from kaffe.org. I am facing a lot of difficulty in using make. could u pl send me step by step implementation procedure for doing this? Pl give me the reference or site where this info is available? sumedha.

Roy Wilson <[EMAIL PROTECTED]> pointed out to me in private
email that Kaffe starves out threads that are contending for a lock.
(I've attached his sample testcase --- somewhat modified).
This behavior results from Kaffe's lock queues being LIFO. Making the
lock queue FIFO fixes his particular problem. (I've attached the
patch, too.) The patch makes the releaser of a lock wake up the
thread on the tail of the queue vs. the thread on the head of the
queue.
However, Godmar has pointed out to me that Kaffe's current
implementation is within the specification (the spec makes no fairness
or liveness guarantees). Additionally, Kaffe breaks broken code
"faster". If you really want fairness, then you'll have to implement
a queue of some sort above the Java primitives.
Anyone else have thoughts on this (or references to JDC
tips/bugs/documentation)?

Hello, I am looking for some tools which can measure the load of a JVM and/or of the computer which run that JVM. Does any body have such soft or some information about that? Thanks. Richard
