-Load data at the QEMU CPU address t1 into t0. t1 has the QEMU CPU address
-type. 'flags' contains the QEMU memory index (selects user or kernel access)
-for example.
-
-Note that "qemu_ld32" implies a 32-bit result, while "qemu_ld32u" and
-"qemu_ld32s" imply a 64-bit result appropriately extended from 32 bits.

+
+Load data at the guest address t1 into t0, or store data in t0 at guest
+address t1. The _i32/_i64 size applies to the size of the input/output
+register t0 only. The address t1 is always sized according to the guest,
+and the width of the memory operation is controlled by flags.
+
+Both t0 and t1 may be split into little-endian ordered pairs of registers
+if dealing with 64-bit quantities on a 32-bit host.
+
+The memidx selects the qemu tlb index to use (e.g. user or kernel access).
+The flags are the TCGMemOp bits, selecting the sign, width, and endianness
+of the memory access.
+
+For a 32-bit host, qemu_ld/st_i64 is guaranteed to only be used with a
+64-bit memory access specified in flags.
