Some people will do anything for crunchons – or “promised future” crunchons.
(A crunchon is a unit of number-crunching.)
I was wondering why this SDK wasn’t already part of the SuSe or FC7
releases. Ten minutes of research later, the answer is: it’s proprietary.
Part of it is proprietary, most of it is not.
The part we are likely to use is all distributed under the GPL, LGPL
or IBM Common License. This includes binutils, the two versions of gcc
(one for the PPE, one for the SPE), gdb, libspe2 (the code that provides
the bridge between the Linux user-space code and the SPEs), etc.

We’re not using those compilers.
We’re not recommending them.
I don’t even install them.
And I get your point
If the above wasn’t enough, it’s also against GNU project policy to
use the mailing list or project documentation to advertise or advocate
for proprietary software.
If the GNU compilers for the CELL aren’t good enough for us, I suggest
that we improve them. If we just can’t exploit the CELL processor without
proprietary software and patented algorithms, then I suggest we go
back to focusing on hosting GNU Radio on hardware that comes with freedom.
If you’ve got some time, please put together a script, etc that pulls
the free stuff down from the Barcelona Supercomputer Center. That’s
where it’s all hosted. Then we can point users at that script and not
at the IBM SDK site.
Here’s a good starting point:
FYI, the kernel and oprofile they’re distributing only work on bare
metal (e.g., IBM QS20 or QS21 bladeserver), not on the hypervisored PS3.
There’s currently lots of churn on the Cell kernels. You can watch
the sausage being made on the cbe-oss-dev mailing list. The IBM and
Sony Linux hackers are there.
