/*
 * Contains SOFTMMU macros expansion for ldx_user and stx_user routines used
 * outside of JIT. The issue is that regular implementation of these routines
 * assumes that pointer to CPU environment is stored in ebp register, which
 * is true for calls made inside JIT, but is not necessarily true for calls
 * made outside of JIT. The way SOFTMMU macros are expanded in this header
 * enforces ldx/stx routines to use CPU environment stored in cpu_single_env
 * variable.
