-description = """My application is built with Clang 16 and the option -fsanitize=memtag-stack.
-It means the the MTE protection is activated for the stack.
-The local variables are tagged and the compiler is often using the STGP instruction "Store Allocation Tag and Pair of registers" in order to transfer the value of two 64-bit registers to memory.
-The following instruction was not working as expected:
-   18004: 69000895     \tstgp\tx21, x2, [x4]
-The value of the second register x2 is not transferred to the memory.
-Only x21 is written.
-
-I think that the issue is in trans_STGP().
-We don't call finalize_memop_pair() like we do for in the general trans_STP().
