2021-06-24target/mips: Fix TCG temporary leaks in gen_pool32a5_nanomips_insn()Philippe Mathieu-Daudé
Fix a pair of TCG temporary leak when translating nanoMIPS SHILO opcode. Fixes: 3285a3e4445 ("target/mips: Add emulation of DSP ASE for nanoMIPS") Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20210530094538.1275329-1-f4bug@amsat.org>
2021-06-24target/mips: Fix potential integer overflow (CID 1452921)Philippe Mathieu-Daudé
Use the BIT_ULL() macro to ensure we use 64-bit arithmetic. This fixes the following Coverity issue (OVERFLOW_BEFORE_WIDEN): CID 1452921: Integer handling issues: Potentially overflowing expression "1 << w" with type "int" (32 bits, signed) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "uint64_t" (64 bits, unsigned).

2021-06-24target/arm: Make VMOV scalar <-> gpreg beatwise for MVEPeter Maydell
In a CPU with MVE, the VMOV (vector lane to general-purpose register) and VMOV (general-purpose register to vector lane) insns are not predicated, but they are subject to beatwise execution if they are not in an IT block. Since our implementation always executes all 4 beats in one tick, this means only that we need to handle PSR.ECI: * we must do the usual check for bad ECI state * we must advance ECI state if the insn succeeds * if ECI says we should not be executing the beat corresponding to the lane of the vector register being accessed then we should skip performing the move Note that if PSR.ECI is non-zero then we cannot be in an IT block.

2021-06-21target/arm: Implement MVE VCLZPeter Maydell
Implement the MVE VCLZ insn (and the necessary machinery for MVE 1-input vector ops). Note that for non-load instructions predication is always performed at a byte level granularity regardless of element size (R_ZLSJ), and so the masking logic here differs from that used in the VLDR and VSTR helpers.

2021-06-21target/arm: Implement widening/narrowing MVE VLDR/VSTR insnsPeter Maydell
Implement the variants of MVE VLDR (encodings T1, T2) which perform "widening" loads where bytes or halfwords are loaded from memory and zero or sign-extended into halfword or word length vector elements, and the narrowing MVE VSTR (encodings T1, T2) where bytes or halfwords are stored from halfword or word elements.
