Thanks for your answer.
Actually, I use the buildroot package provided by Gaisler on their
website to build a Linux for the Leon3 architecture.
They provide toolchains binaries as well and also the bcc sources.
So what I have is a working Leon3+Linux architecture on a Virtex5 FPGA card.
What I'm trying to do is to compile and run a test program on the Linux.
Then comes the issue : when I compile this test code with the cross
compiler binary provided, it compiles and runs well on the Linux.
But, when I try to compile it with a cross compiler that I have built
using the bcc sources, it fails with the illegal instruction trap.
Here is the output of both -v :
Provided cross compiler : sparc-linux-gcc -v
Using built-in specs.
Target: sparc-leon-linux-gnu
Configured with:

Thread model: single
gcc version 3.4.4
(I also tried with a 4.4.2 too : same illegal instruction issue).
