Excuse me, I want to consult the related information about SPR.
For SPRs (Special Purpose Register) under tilegx, I can not get related
documents (I only got the tilepro related document for SPR). After read
through the source code of Linux kernel for tile, I guess:
- SPRs are in "arch/tile/include/uapi/arch/spr_def_64.h".
- SPRs are all 64-bit registers (I referenced the 'interrupt_mask' and
CHIP_HAS_SPLIT_INTR_MASK to know about it).
If what I guess is incorrect, please let me know. And welcome to provide
tilegx SPR related documents, too.
Thanks.

I'm not sure whether Tilera can simply re-release the tilegx-specific stuff
from binutils as a separate tarball with GPL v2 licensing. Hopefully we can
avoid having to figure that out. :-)
I believe it is theoretically possible (the usual FSF copyright arrangements
involve the original authors giving the copyright to the FSF but being
granted back a right to distribute their work under other licenses).
However it is definitely a "check with your lawyers" kind of question
and I entirely appreciate the desire to avoid having to go down that
route :-)
For me, the main feature of kernel disassembly implementation is almost
the same as the feature of binutils disassembly implementation. And all
of related code are not quite much (only several thousand lines),
So at present, I guess, we needn't consider more about the related
license.
Thanks
