tcg_out_label is always called with a third argument of pointer type which was casted to tcg_target_long. These casts can be avoided by changing the prototype of tcg_out_label. There was also a cast to long. For most hosts with sizeof(long) == sizeof(tcg_target_long) == sizeof(void *) this did not matter, but for w64 it was wrong. This is fixed now.

x86 cannot provide an optimized generic deposit implementation. But at least for a few special cases, namely for writing bits 0..7, 8..15, and 0..15, versions using only a single instruction are feasible. Introducing such limited support improves emulating 16-bit x86 code on x86, but also rarer cases where 32-bit or 64-bit code accesses bytes or words.

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. Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

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. Signed-off-by: NRichard Henderson <rth@twiddle.net> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

Add more OPC values, and tgen_arithr. Use the later throughout. Note that normal reg/reg arithmetic now uses the Gv,Ev opcode form instead of the Ev,Gv opcode form used previously. Both forms disassemble properly, and so there's no visible change when diffing log files before and after the change. This change makes the operand ordering within the output routines more natural, and avoids the need to define an OPC_ARITH_EvGv since a read-modify-write with memory is not needed within TCG.
