* target/mips: Convert Vr54xx MSA* opcodes to decodetreePhilippe Mathieu-Daudé2021-08-251-0/+4
| | | | | | | | | | | | | Convert the following Integer Multiply-Accumulate opcodes: * MSAC Multiply, negate, accumulate, and move LO * MSACHI Multiply, negate, accumulate, and move HI * MSACHIU Unsigned multiply, negate, accumulate, and move HI * MSACU Unsigned multiply, negate, accumulate, and move LO Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20210808173018.90960-8-f4bug@amsat.org>

* target/mips: Convert Vr54xx MACC* opcodes to decodetreePhilippe Mathieu-Daudé2021-08-251-0/+9
| | | | | | | | | | | | | | | | | Convert the following Integer Multiply-Accumulate opcodes: * MACC Multiply, accumulate, and move LO * MACCHI Multiply, accumulate, and move HI * MACCHIU Unsigned multiply, accumulate, and move HI * MACCU Unsigned multiply, accumulate, and move LO Since all opcodes are generated using the same pattern, we add the gen_helper_mult_acc_t typedef and MULT_ACC() macro to remove boilerplate code.

* target/mips: Introduce decodetree structure for NEC Vr54xx extensionPhilippe Mathieu-Daudé2021-08-251-0/+8
The decoder is called but doesn't decode anything. This will ease reviewing the next commit. Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20210801235926.3178085-3-f4bug@amsat.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
