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