newlib is broken for spu target since 2.5.0.20170623

[Michał Dec]

Hello,

I wanted to make a crosscompiler for the SPU on my PS3 with the newest 
newlib 3.3.0 but it failed. I've reported this issue to my distribution 
here https://bugs.gentoo.org/732206 and my investigations turned out 
this has been broken for some time now. I've also made a diff of the 
last working version and the first broken version here 
https://github.com/grepwood/newlib/commit/831b6666af1f83ac173b491a5c191246203ddc37 
and I can see there's something wrong POSIX threads but I'm not entirely 
sure. Could anyone assist please? I know the SPU target is pretty much 
dead, but there are also plans to bring the open-source PS3 SDK PSL1GHT 
up to speed with new networking code from newlib, and they will also be 
blocked if they can't get a compiler for the SPU.

Best regards,

Michał Dec

Well the SPU back-end for GCC was removed in GCC 10.x and gdb release
this year.  So I am thinking we should remove support for spu from the
newlib too.  I am shocked it was removed from binutils though.

Thanks,

I meant I am shocked, it has NOT been removed from binutils yet.
I once worked on the SPU back-end but it has been over 10 years since
I last worked on it and had the ability to do such too.
