Hello!
We are working with Kaffe and RTEMS for embedded applications.
I was succeeded in cross-compiling Kaffe for RTEMS on ERC32, with this
settings:
./configure --target=sparc-rtems --with-staticlib --with-staticvm
--with-engine=intrp --without-x
But it doesn't work properly: it crashs. :(
Anyway, we are trying to estimate its performance and memory size.
Any reference about them are welcome, particularly about performance
in the start-up and in running status (times, etc)
About size, I have identified these files to be in the built-in
filesystem:
-rw-r--r-- 1 omt wms 413236 Jan 26 11:03 libio.a
-rw-r--r-- 1 omt wms 659 Jan 26 11:03 libio.la
-rw-r--r-- 1 omt wms 2019280 Jan 26 11:04 libnative.a
-rw-r--r-- 1 omt wms 680 Jan 26 11:04 libnative.la
-rw-r--r-- 1 omt wms 885137 Jan 26 11:02 Klasses.jar
-rw-r--r-- 1 omt wms 428 Jan 27 14:34
HelloWorldApp.class
Just for a simple HelloWorldApp!
The Kaffe executable with the RTEMS OS (kaffe is a task) is:
-rwxr-xr-x 1 omt wms 2601580 Jan 26 11:01 Kaffe0.exe
And if I tar the files and attach it as an object:
-rw-r--r-- 1 omt wms 3328000 Jan 27 14:46
kaffe_filesystem.tar_ALL
So, Kaffe+RTEMS+filesystem_tar =
-rwxr-xr-x 1 omt wms 5952660 Jan 28 09:45 Kaffe5.exe
At runtime it needs to untar the filesystem, so the amount of memory
would be:
9'26 Mb a huge amount!
I will be looking forward to your comments, suggestions and performances
analysis!
Best regards,
Oscar
PS: I have just started to try gcj, any comments?
