70d705fd46 tcg/ppc/tcg-target.c: Avoid 'set but not used' gcc warnings
Move the declaration and initialisation of some variables in
tcg_out_qemu_ld and tcg_out_qemu_st inside CONFIG_SOFTMMU, to
avoid the "variable set but not used" warning of gcc 4.6.

cea5f9a28f cpu-exec.c: avoid AREG0 use
Make functions take a parameter for CPUState instead of relying
on global env. Pass CPUState pointer to TCG prologue, which moves
it to AREG0.

Thanks to Peter Maydell and Laurent Desnogues for the ARM prologue
change.

Revert the hacks to avoid AREG0 use on Sparc hosts.

Move cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h.

Compile the file without HELPER_CFLAGS.

3b6dac3416 tcg: Add TYPE parameter to tcg_out_mov.
Mirror tcg_out_movi in having a TYPE parameter.  This allows x86_64
to perform the move at the proper width, which may elide a REX prefix.

Introduce a TCG_TYPE_REG enumerator to represent the "native width"
of the host register, and to distinguish the usage from "pointer data"
as represented by the existing TCG_TYPE_PTR.

Update all targets to match.

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.

86feb1c860 tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.
Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operands
sign-extended in 64-bit registers (regardless of the "real" sign
of the operand).  For that, we need to be able to distinguish
between a 32-bit load with a 32-bit result and a 32-bit load with
a given extension to a 64-bit result.  This distinction already
exists for the ld* loads, but not the qemu_ld* loads.

Reserve qemu_ld32u for 64-bit outputs and introduce qemu_ld32 for
32-bit outputs.  Adjust all code generators to match.
