[kaffe] retrieving method arguments in jit

[kalyan ram]

Hai
How to retrieve method argument in jit? For
example, if I have a method : 
Java code - 
  for(int a=0;a10;a++) {
test(int a) 
  { //do something with a }
   }

I need access to value of a in the method
soft_fixup(..) in JIT. Can anyone tell me how to get
that?

Thanks
--Ram

Hai 
   WHen I try to build kaffe,I get the error
support.c:456: warning: `jfloat' is promoted to

not `jfloat' to `va_arg')

`INDEX_REGS' while reloading `asm'
support.c:551: error: can't find a register in class

[kaffe] problem in building the jit+interpreter patch

[kalyan ram]

Hai
  On the following website
http://www.flux.utah.edu/~tullmann/kaffe/jitintrp/
, there is a patch available. If someone  has recently
worked with this patch,please tell me how to build it.
For the normal kaffe, the steps are build are :
configure, make , make install. But this does not work
for this patch.
The steps I followed are:
1../configure --with-engine=jit
2. make (the errors come here).

I would appreciate the help.
Thanks

[kaffe] invoking interpreter execution in jit3

[kalyan ram]

Hai
Is it possible to invoke the interpreter execution
engine in the Jit3? For example, for a particular
method I want the interpreter mode of kaffe to execute
rather than the jit3. 

Thanks

[kaffe] shutdown a thread

[kalyan ram]

Hai
  I have implemented a pthread in kaffe interpreter
and the problem is kaffe does not shutdown after the
program executes because the pthread is still running
in machine.c.Is there a way to kill the thread after
the execution so that kaffe VM shuts down cleanly.

Any insights would be appreciated.

Thanks
Ram

[kaffe] question on jit

[kalyan ram]

Hai
Can anyone point me to a file and function in
kaffe where exactly the execution of machine code
(after jit) in jit mode is done?I can see that in
soft_fixup_trampoline in soft.c,trampoline is replaced
to point to the native code.For example,in intrp mode,
runVirtualMachine in machine.c is where bytecode
execution is done.My guess is samething happens in jit
at machine code level.Where is it done?

Thanks
Ram

[kaffe] accessing a variable

[kalyan ram]

Hai
   I started a thread in thread.c file which is
running a tcp client(this is working fine on kaffe).In
that thread,I am having a data structure(like an
array).But for simplicity,I am using a small integer
variable.I need to be able to access that variable
from kaffe.def file which is part of
intrp/machine.c(interpreter version of kaffe).I put a
variable in thread.h (because it is included in
machine.c file)and tried to print that variable in
kaffe.def.But when I make,kaffe says multiple
definition or sometimes unrecognized.Is there is
any workaround for that?How to make a variable in
thread.c be recognized in kaffe.def?
Any insights will be appreciated!

Thanks
Ram

[kaffe] help with make install

[kalyan ram]

Hai
When I change anything in kaffe.def file,I
generally go to intrp directory and open the machine.c
file and press a space and then at the top directory
do the make install for recompiling the kaffe.When I
just modify the kaffe.def file,there is no change.
Is there a better way to recompile the kaffe with make
install after modifying kaffe.def file?

Thanks
