How to include ppc_intrinsics.h with gcc12?

[barracuda156]

@iains
Some ports expect an arch-specific intrinsics header. With gcc12 I only find ppu_intrinsics.h (for Cell): /opt/local/lib/gcc12/gcc/ppc-apple-darwin10/12.1.0/include/ppu_intrinsics.h. Then there is ppc_intrinsics.h in OS includes, but for gcc-4.2: /usr/include/gcc/darwin/4.2/ppc_intrinsics.h. What should be done about this?

[iains]

the file ppc_intrinsics.h is an Apple-local change:

/* APPLE LOCAL file PPC_INTRINSICS */

However, there is a copy of if in the old Apple branch on the FSF server, so that (in principle, AFAIU the rules) we could import it into master and have it installed. ... another thing for the "TODO" ;)

@iains Is it something publicly available to try it out? Or can it be added into the next subversion of gcc12? :)

@iains Should I open an issue with GCC for that end? It is arguably better to fix this for everyone rather than just for myself by including an OS header.

(I can try working on it myself, and definitely do testing, but I need to have some outline of what is to be done.)

Yes - but please open the issue for upstream GCC (i.e. on bugzilla) since this is not specific to these branches.

Yes, sure. Thank you.
