Hi all,
Previously there was *TARGET_ALIGNED_ONLY* option that caused all memory
accessed to be aligned, now it seems to be removed.
Is there a way to achieve memory access alignment with QEMU v9.0.0 when I
am building a custom target?

Explicitly add MO_ALIGN to the MemOp argument of tcg_gen_qemu_{ld,st}_{i32,i64,i128}.
