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.

TCG_TARGET_REG_BITS can be determined by the compiler, so there is no need to declare it for each individual tcg target. This is especially important for new tcg targets which will be supported by the tcg interpreter. Signed-off-by: NStefan Weil <weil@mail.berlios.de> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

By always defining these symbols, we can eliminate a lot of ifdefs. To allow this to be checked reliably, the semantics of the TCG_TARGET_HAS_* macros must be changed from def/undef to true/false. This allows even more ifdefs to be removed, converting them into C if statements. Signed-off-by: NRichard Henderson <rth@twiddle.net> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

Copy propagation introduced in 22613af4 considered only global registers. However, register temps and stack allocated locals must be handled differently because register temps don't survive across brcond. Fix by propagating only within same class of temps.

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>

When compiling with DEBUG_TCGV enabled, make the TCGv_ptr type distinct from TCGv_i32/TCGv_i64. This means that using an i32 or i64 TCG op to manipulate a TCGv_ptr will always be detected at compile time, rather than only if compiling on a host system with the other word size. NB: the tcg_add_ptr and tcg_sub_ptr macros have been removed as they were not used anywhere.

Add support (if CONFIG_DEBUG_TCG is defined) for debugging leakage of temporary variables. Generally any temporaries created by a target while it is translating an instruction should be freed by the end of that instruction; otherwise carefully crafted guest code could cause TCG to run out of temporaries and assert. By calling tcg_check_temp_count() after each instruction we can check that we are not leaking temporaries in this way.

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.

When compiled with CONFIG_DEBUG_TCG, this code looks for missing, duplicate and wrong entries in the op definitions.
