To avoid some of the cell size vs. pointer size issues, use 64-bit cells on ppc64. Suggested by Segher.
This involves handling lack of 128-bit type and compiling 64-bit libgcc parts, copied from sparc64.
Hopefully fixes compilation on 64-bit host, too.
I thought ppc64 OpenFirmware uses 32bit cells?
That's what I thought, too... but Segher said otherwise in January, and Tarl said the internal cell size (that I'm trying to change here) were different from the guest-visible 32-bit cell size. Through the use of prog_arg_t the CIF is supposed to remain 32-bit.
Oh, too quick in replying :). You're changing the "cell" type which is used all over the place with sizeof() to figure out the cell size of guest visible (device tree) fields. I don't see how it could not be guest exposed.
