This allows an output operand to match an input operand
only when the input operand needs a register.
Backports commit 17280ff4a5f264e01e55ae514ee6d3586f9577b2 from qemu
This will let us choose how to interpret a given constraint
depending on whether the opcode is 32- or 64-bit. Which will
let us share more constraint combinations between opcodes.
At the same time, change the interface to return the advanced
pointer instead of passing it in/out by reference.
Backports commit 069ea736b50b75fdec99c9b8cc603b97bd98419e from qemu
This will allow the target to tailor the constraints to the
auto-detected ISA extensions.
Backports commit f69d277ece43c42c7ab0144c2ff05ba740f6706b from qemu
A couple of places where it was easy to identify a right-shift
followed by an extract or and-with-immediate, and the obvious
sign-extract from a high byte register.
Backports commit 04fc2f1c8fc030a11e08e81bb926392c0991282a from qemu
Use the new primitives for UBFX and SBFX.
Backports commits 59a71b4c5b4ef2ef6425b9e21c972dd5bf450275 and 86c9ab277615af4e0389eb80a83073873ff96c86 from qemu
Since we can no longer use matching constraints, this does
mean we must handle that data movement by hand.
Backports commit 752b1be94757de906b9c24ebc8f5e6aa54b96b23 from qemu
This lets us expose facilities to TCG_TARGET_HAS_* defines
directly, rather than hiding behind function calls.
Backports commit b2c98d9d392c87c9b9e975d30f79924719d9cbbe from qemu
This allows us to use this detection within the TCG_TARGET_HAS_*
macros, instead of requiring a function call into tcg-target.inc.c.
Backports commit 40b2ccb156534f5d5f1d110a6ce008d87ee10af1 from qemu
While we don't require a new opcode, it is handy to have an expander
that knows the first source is zero.
Backports commit 07cc68d52852bf47dea7c402b46ddd28248d4212 from qemu
Adds tcg_gen_extract_* and tcg_gen_sextract_* for extraction of
fixed position bitfields, much like we already have for deposit.
Backports commit 7ec8bab3deae643b1ce579c2d65a244f30708330 from qemu
This patch introduces a helper to query the iotlb entry for a
possible iova. This will be used by later device IOTLB API to enable
the capability for a dataplane (e.g vhost) to query the IOTLB.

tcg_out_ldst: using a generic ALIAS_PADD to avoid ifdefs
tcg_out_ld: generates LD or LW
tcg_out_st: generates SD or SW
Backports commit 32b69707df3365aadaad1d058044a7704397ec62 from qemu
tcg_out_mov: using OPC_OR as most mips assemblers do;
tcg_out_movi: extended to 64-bit immediate.
Backports commit 2294d05dab503d11664e73712c7f250fd0bf9e3b from qemu
Without the mips32r2 instructions to perform swapping, bswap is quite large,
dominating the size of each reverse-endian qemu_ld/qemu_st operation.
Create two subroutines in the prologue block. The subroutines require extra
reserved registers (TCG_TMP[2, 3]). Using these within qemu_ld means that
we need not place additional restrictions on the qemu_ld outputs.
Backports commit 7f54eaa3b78d71cb57e45a719980f9b5ff06d21c from qemu
Bulk patch adding 64-bit opcodes into tcg_out_op. Note that
mips64 is as yet neither complete nor enabled.
Backports commit 0119b1927d531f3fac22b9b4da01dafc23644973 from qemu
Since the mips manual tables are in octal, reorg all of the opcodes
into that format for clarity. Note that the 64-bit opcodes are as
yet unused.

Also manage word and byte operands and fix the computation of
overflow in the case of M68000 arithmetic shifts.
Backports commit 367790cce8e14131426f5190dfd7d1bdbf656e4d from qemu
Report this properly via exception and, importantly, allow
the disassembler the chance to tell us what insn is not handled.

680x0 movem can load/store words and long words and can use more
addressing modes. Coldfire can only use long words with (Ax) and
(d16,Ax) addressing modes.
Backports commit 7b542eb96d7d5d9266a9c0425f05d49c8e6df2f9 from qemu
Implement CAS using cmpxchg.
Implement CAS2 using helper and either cmpxchg when
the 32bit addresses are consecutive, or with
parallel_cpus+cpu_loop_exit_atomic() otherwise.
