This is a linux-user only port, emulating a 32-bit only version of a
pa-2.0 cpu. This is good enough to do well with both the gcc and glibc
testsuites. Helge Deller has provided invaluable assistance testing
with a more complete debian chroot.
What's missing:
* Space registers. Since Linux sets them all equal (for a flat
address space) and uses them like address-space identifiers,
we can simply set them all to 0 and ignore them.
* Architecture subsets. There's no markup for running a pure pa1.0
or pa1.1 cpu. I happily accept everything up to pa2.0 at the moment.
* Wide mode. While I have pa2.0 instructions, I don't support running
in 64-bit mode. Since neither the linux kernel nor glibc support a
64-bit userland, it would be a lot more work than just adding the insns.
* Multimedia instructions. These are tied to wide mode, so...
When squashing the patches down from my development tree, I wanted to
preserve Helge's contributions, so the linux-user part is more patches
than I would normally have preserved.
