When MIPS_DEBUG_DISAS is defined the gen_logic_imm, gen_slt_imm,
gen_cond_move, gen_logic and gen_slt functions cause errors because ctx

The microMIPS SWP and SDP instructions do not modify GPRs. So their
behavior is well defined when RD equals BASE. The MIPS Architecture
Verification Programs (AVPs) check that they work as expected. This
is required for AVPs to pass.

These functions are defined in the tcg target specific file
tcg-target.c.
The forward declarations assert that every tcg target uses
the same function prototype.

Unlike other tcg target code generators, this one does not generate
machine code for some cpu. It generates machine independent bytecode
which is interpreted later.
This allows running QEMU on any host.
Interpreted bytecode is slower than direct execution of generated
machine code.

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.

Hello,
these patches add a new code generator (TCG target) to qemu.
Unlike other tcg target code generators, this one does not generate
machine code for some cpu. It generates machine independent bytecode
which is interpreted later. That's why I called it TCI (tiny code
interpreter).

The number of registers needed for the return value of TCG opcode
INDEX_op_call is calculated in function tcg_gen_callN (nb_rets).
It can be 0 or 1, for 32 bit hosts also 2 (return 64 bit value in
two 32 bit registers).
Some TCG implementations reserve
It was introduced with commit 54936004fddc52c321cb3f9a9a51140e782bed5d
