Missing glue/v4-powerpc64/ipc.h?

[vmlemon]

Hi,

I've recently been trying to build Pistachio, using the POWER4 configuration, on a little-endian POWER9 machine (I'm trying to do a baseline build, so I can start porting the kernel to Cell, and POWER9), using GCC 9.2.1 (which isn't obviously a supported configuration), and despite making reasonable progress (was necessary to change

 cmp 

, to

 cmpd

, in kernel/src/platform/ofpower4/head.S, and patch up some other source files), I'm getting stuck with a missing tcb_layout.h, and asmsyms.h, to build more of the kernel, but I can't generate these, since ipc.h seems to be missing, for some reason.

Is this intentional? If not, is it safe to copy the 32-bit version, if I want to continue on with my project? (Documenting my adventures, in vmlemon/Orion#1, at the moment).

Thanks in advance...
