Hi,
The attached patch adds preliminary HPPA (PA-RISC) Linux host support.
It is currently capable of running the 'mips-test-0.2' test image, and
it can run simple programs under qemu-i386.
The 'use spinlock_t for interrupt_lock' patch should be applied first.
I have tried to avoid any invasive changes that could affect other
hosts, but please tell me if there's anything that can be improved.
I am not yet sure that the 'stack-grows-up' handling that I have added
to tcg_reg_alloc_call() is correct -- however, HPPA is almost alone[1]
in using a stack that grows upwards, so this should not be a problem.
Many thanks to Randolph Chung for much of the work on the earlier
version of this patch[2], which applies to QEMU 0.9.1.
I've attached hppa-dis.c separately (as it's 2834 lines taken from
GNU binutils) to make it easier to review the rest of the changes.
hppa-dis.c was retrieved prior to the switch to the GPL v3.
Here's a diffstat of the changes, excluding hppa-dis.c:
Makefile.target | 8

cpu-all.h | 11

[1] IA64 also has a register stack, similar to SPARC's register windows,
which grows upwards.
