Thanks for finding this. I agree the fix is required, but I think I'd
prefer it if the thumb code for this case handled it in the same way
the disas_arm_insn() code does:
loaded_base = 0;
TCGV_UNUSED(loaded_var);
[...]
tmp = gen_ld32(addr, IS_USER(s));
if (i == 15) {
gen_bx(s, tmp);
} else if (i == rn) {
loaded_var = tmp;
loaded_base = 1;
} else {
store_reg(s, i, tmp);
}
[...]
if (loaded_base) {
store_reg(s, rn, loaded_var);
}
