-AVX instruction VMOVDQU implementation error for YMM registers
-Bug Description
-Hi,
-
-Tested with Qemu 4.2.0, and with git version bddff6f6787c916b0e9d63ef9e4d442114257739.
-
-The x86 AVX instruction VMOVDQU doesn't work properly with YMM registers (32 bytes).
-It works with XMM registers (16 bytes) though.
-
-See the attached test case `ymm.c`: when copying from memory-to-ymm0 and then back from ymm0-to-memory using VMOVDQU, Qemu only copies the first 16 of the total 32 bytes.
-
-```
-user@ubuntu ~/Qemu % gcc -o ymm ymm.c -Wall -Wextra -Werror
-
-user@ubuntu ~/Qemu % ./ymm

-
-This seems to be because in `translate.c > gen_sse()`, the case handling the VMOVDQU instruction calls `gen_ldo_env_A0` which always performs a 16 bytes copy using two 8 bytes load and store operations (with `tcg_gen_qemu_ld_i64` and `tcg_gen_st_i64`).
-
-Instead, the `gen_ldo_env_A0` function should generate a copy with a size corresponding to the used register.
-
-```
-static void gen_sse(CPUX86State *env, DisasContext *s, int b,
-                    target_ulong pc_start, int rex_r)
-{
-        [...]
-        case 0x26f: /* movdqu xmm, ea */
-            if (mod != 3) {
-                gen_lea_modrm(env, s, modrm);
-                gen_ldo_env_A0(s, offsetof(CPUX86State, xmm_regs[reg]));
-            } else {
-        [...]
-```
-
-```
-static inline void gen_ldo_env_A0(DisasContext *s, int offset)
-{
-    int mem_index = s->mem_index;
-    tcg_gen_qemu_ld_i64(s->tmp1_i64, s->A0, mem_index, MO_LEQ);
-    tcg_gen_st_i64(s->tmp1_i64, cpu_env, offset + offsetof(ZMMReg, ZMM_Q(0)));
-    tcg_gen_addi_tl(s->tmp0, s->A0, 8);
-    tcg_gen_qemu_ld_i64(s->tmp1_i64, s->tmp0, mem_index, MO_LEQ);
-    tcg_gen_st_i64(s->tmp1_i64, cpu_env, offset + offsetof(ZMMReg, ZMM_Q(1)));
