This isn't a regression IMHO, independent of this bug -msdata=eabi is non-functional in gcc
since at least gcc-2.95. So even if _this_ bug is fixed for 3.3.1 as a regression, -msdata=eabi
will still be non-functional!
If, however, we really want to fix all of the PPC sdata bugs for 3.3.x, I request backporting the
gcc.dg/ppc-sdata-[12].c testcases to the 3.3 branch as a first step.

This is surprise for me. I use gcc-2.95 with -msdata=eabi all the time for a
few years now and I didn't notice any problems with it yet. On the other hand,
I've immediately noticed the problem in 3.3 at the first try.

r0 is used as a pointer to sdata2, this is a bug, it should be r2. And since only r2 is initialized in
the ecrt*.o files, how can this work? Besides that, even if you initialize r0 manually, it is
practically clobbered in about every function.

Based on Franz's comments, this bug is not really a regression at all.
I've therefore removed the regression tags.

> r0 is used as a pointer to sdata2, this is a bug, it should be r2.
No, the %r0 you see is fake. In the object file it's a special relocatable
symbol that is resolved to either 2 (r2) or 13 (r13) by the linker depending on
actual output section the symbol refers to, so there is no bug here.
As there is no bug at this point, the:

is wrong as Franz's comments are wrong.

I have fixed this bug (and another) against the 3.3.3 release. I am not a GCC
developer, just a hack that loves GCC. The fix works for my needs, but most
likely is not how it should be implemented. I could send a diff or a patch if
the developers are interested in seeing what I did.
