Aurelien Jarno 626cd050e2 tcg: remove obsolete jmp op
The TCG jmp operation doesn't really make sense in the QEMU context, it
is unused, it is not implemented by some targets, and it is wrongly
implemented by some others.

This patch simply removes it.

Stefan Weil 6673f47da2 tci: Fix for AREG0 free mode
Support for helper functions with 5 arguments was missing
in the code generator and in the interpreter.

There is no need to pass the constant TCG_AREG0 from the
code generator to the interpreter. Remove that code for
the INDEX_op_qemu_st* opcodes.

Blue Swirl 89c33337fd Remove unused CONFIG_TCG_PASS_AREG0 and dead code
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets,
remove dead code and support for !CONFIG_TCG_PASS_AREG0 case.

Remove dyngen-exec.h and all references to it. Although included by
hw/spapr_hcall.c, it does not seem to use it.

Remove unused HELPER_CFLAGS.

Running the Windows 7 (64 bit) boot process needs INDEX_op_bswap64_i64.
It was already implemented, but untested. Remove the TODO() statement.

Stefan Weil 17904bcfb7 tci: Fix wrong macro name for debug code
Code which is compiled with CONFIG_TCG_DEBUG (set by configure option
--enable-debug-tcg) should not disable the assert macro by
defining NDEBUG.

With the wrong macro name CONFIG_TCG_DEBUG, all assertions in tci.c
were completely useless because NDEBUG was always defined.

Stefan Weil c3ca04679e tci: GETPC() macro must return an uintptr_t
Change the data type of tci_tb_ptr, so GETPC() returns an
uintptr_t now (like for all other TCG targets).

This completes commit 2050396801
and fixes builds with TCI.

Stefan Weil 3b2aba2f13 tci: Support targets with CONFIG_TCG_PASS_AREG0 (fix broken build)
Builds with --enable-tcg-interpreter failed because more and more
targets (currently alpha and sparc) replaced the global env in AREG0
by function parameters.

Convert the TCG interpreter to use the new helper functions and add
defines for those targets which still use AREG0.

Stefan Weil 69784eaec3 w64: Fix data type of next_tb and tcg_qemu_tb_exec
next_tb is the numeric value of a tcg target (= QEMU host) address.

Using tcg_target_ulong instead of unsigned long shows this and makes
the code portable for hosts with an unusual size of long (w64).

The type cast '(long)(next_tb & ~3)' was not needed (casting
unsigned long to long does not change the bits, and nor does
casting long to pointer for most (= all non w64) hosts.
It is removed here.

Macro or function tcg_qemu_tb_exec is used to set next_tb.
The function also returns next_tb. Therefore tcg_qemu_tb_exec
must return a tcg_target_ulong.

Andreas Färber 9349b4f9fd Rename CPUState -> CPUArchState
Scripted conversion:
  for file in *.[hc] hw/*.[hc] hw/kvm/*.[hc] linux-user/*.[hc] linux-user/m68k/*.[hc] bsd-user/*.[hc] darwin-user/*.[hc] tcg/*/*.[hc] target-*/cpu.h; do
    sed -i "s/CPUState/CPUArchState/g" $file
  done

All occurrences of CPUArchState are expected to be replaced by QOM CPUState,
once all targets are QOM'ified and common fields have been extracted.
