Stefan Weil f038e8f79b Use correct cflags for kvm-kmod when cross compiling
Using $pkgconfig instead of pkg-config will use
${cross_prefix}pkg-config if that is available.

This fix is needed for cross compilations without
modified PATH. Without the fix, PATH must be modified
to find the cross pkg-config before the native
pkg-config.

Richard Henderson fd76e73a10 tcg-hppa: Finish the port.
Delete inline functions from tcg-target.h that don't need to be there,
move the others to tcg-target.c.  Add 'Z', 'I', 'J' constraints for
0, signed 11-bit, and signed 5-bit respectively.  Add GUEST_BASE support
similar to ppc64, with the value stored in a register.  Add missing
registers to reg_alloc_order.  Add support for 12-bit branch relocations.
Add functions for synthetic operations: addi, mtctl, dep, shd, vshd, ori,
andi, shifts, rotates, multiply, branches, setcond.  Split out TLB reads
from qemu_ld and qemu_st; fix argument loading for tlb external calls.
Generate the prologue.

Paul Brook 355b194369 Split TLB addend and target_phys_addr_t
Historically the qemu tlb "addend" field was used for both RAM and IO accesses,
so needed to be able to hold both host addresses (unsigned long) and guest
physical addresses (target_phys_addr_t).  However since the introduction of
the iotlb field it has only been used for RAM accesses.

This means we can change the type of addend to unsigned long, and remove
associated hacks in the big-endian TCG backends.

We can also remove the host dependence from target_phys_addr_t.

Aurelien Jarno 477ba62001 tcg: initial ia64 support
A few words about design choices:
* On IA64, instructions should be grouped by bundle, and dependencies
  between instructions declared. A first version of this code tried to
  schedule instructions automatically, but was very complex and too
  invasive for the current common TCG code (ops not ending at
  instruction boundaries, code retranslation breaking already generated
  code, etc.)  It was also not very efficient, as dependencies between
  TCG ops is not available.
  Instead the option taken by the current implementation does not try
  to fill the bundle by scheduling instructions, but by providing ops
  not available as an ia64 instruction, and by offering 22-bit constant
  loading for most of the instructions. With both options the bundle are
  filled at approximately the same level.

* Up to 128 registers can be affected to a function on IA64, but TCG
  limits this number to 64, which is actually more than enough. The
  register affectation is the following:
  - r0: used to map a constant argument with value 0
  - r1: global pointer
  - r2, r3: internal use
  - r4 to r6: not used to avoid saving them
  - r7: env structure
  - r8 to r11: free for TCG (call clobbered)
  - r12: stack pointer
  - r13: thread pointer
  - r14 to r31: free for TCG (call clobbered)
  - r32: reserved (return address)
  - r33: reserved (PFS)
  - r33 to r63: free for TCG

* The IA64 architecture has only 64-bit registers and no 32-bit
  instructions (the only exception being cmp4). Therefore 64-bit
  registers and instructions are used for 32-bit ops. The adopted
  strategy is the same as the ABI, that is the higher 32 bits are
  undefined. Most ops (and, or, add, shl, etc.) can directly use
  the 64-bit registers, while some others have to sign-extend (sar,
  div, etc.) or zero-extend (shr, divu, etc.) the register first.

Juergen Lock f01576f185 Get bsd-user host page protection code working on FreeBSD hosts
Use kinfo_getvmmap(3) on FeeBSD >= 7.x and /compat/linux/proc on older
FreeBSD.  (kinfo_getvmmap is preferred since /compat/linux/proc is
usually only mounted on hosts also using the Linuxolator.)

This patch is a bit hacky because the includes needed for kinfo_getvmmap
conflict with other definitions in exec.c by default so I had to `trick
around' a little, but I built the result in FreeBSD 6.4-stable and
7.2-stable tbs and on 8-stable on the host so the hacks at least
should be stable.  (If this is a problem maybe we could also move the
kinfo_getvmmap invocations into a seperate source file but that would
be more work...)

1) fixing a typo ($sd_cflags).  The typo has been there since commit
1ac88f2 (remove sdl_static. Just do the right thing if static is yes,
2009-07-27).

2) fixing an erroneous "test `... | grep > /dev/null`" idiom that would
never succeed since grep's output would be empty;

3) checking the status code after executing sdl-config --static --libs;
this is needed for the next patch only.

Juan has contributed a cool Makefile infrastructure that enables us to drop

Move shared obj-y definitions to Makefile.objs, prefixed {common-,hw-,user-},

Replace HWLIB by HWDIR, specifying only the directory.

Drop --whole-archive and ARLIBS in Makefiles and configure.

Drop GENERATED_HEADERS dependency in rules.mak, since this rebuilds all
common objects after generating a target-specific header; add dependency
rules to Makefile and Makefile.target instead.

- Changes to user object paths ("Quickfix for libuser.a drop") were obsoleted

Michael S. Tsirkin be17dc90b5 configure: use correct cflags in compiler checks
linux-user build on fedora 11 breaks because fallocate
is broken on that system if -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64
are specified, which is what QEMU uses.

We do have a configure check to catch this and disable fallocate,
however, it turns out that default QEMU_CFLAGS/LDFLAGS were assigned in
script *after* all compiler checks: so during checks we were not running
compiler with same flags that we used for build later.

Fix this by moving QEMU_CFLAGS to before compiler checks, and using
comple_prog when checking for fallocate.  This also fixes the fact that
we do some compiler checks while assigning the flags, right below a
comment that says "no cc tests beyond this point".

Aurelien Jarno afa05235a5 tcg: initial mips support
Based on a patch from Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org>

A few words about design choices:
* Two registers, at and t0, are reserved for TCG internal use. They are
  useful for bswap and 64-bit ops.
* Most ops supports a constant argument with value 0, which is actually
  mapped to the zero register.
* While the at register is available for constant loading, ops only
  support a limited range of constants. TCG does a better job doing the
  register allocation and constant loading by itself. There are plenty of
  registers available anyway.
