[Qemu-devel] [PULL 00/26] New hppa-linux target support

[Richard Henderson]

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.
