I wrote a test program and it looks ok:

davem at sunset:~/src/GIT/sparc-2.6.17$ gcc -m32 -O -o foo foo.c
davem at sunset:~/src/GIT/sparc-2.6.17$ ./foo
SPARC32
foo src: 0
foo dst: 28
bar a: 0
bar b: 28
davem at sunset:~/src/GIT/sparc-2.6.17$ gcc -m64 -O -o foo foo.c
davem at sunset:~/src/GIT/sparc-2.6.17$ ./foo
SPARC64
foo src: 0
foo dst: 28
bar a: 0
bar b: 28
