- before they are used in idecode tables.
+ * sim_calls.c (zfree): Call free correctly.
- * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
- idecode_crack_insn): Add is_inline_function argument to code
- printing cracker functions which indicates if STATIC_IDECODE or
- STATIC_INLINE_IDECODE should be used for definition. For
- idecode_crack_insn (which implies not duplicating/expanding) don't
- declare function as inline - we assume that the only time this is
- code is generated is when things are being tested. For
- idecode_crack_leaf, make static (instead of INLINE) if the

- should be output. Depending on situtation call accordingly:
- functions (not instruction semantic routines) are always inline;
- Semantic routines are made inline when there is no icache (cache
- will contain the function address) and are duplicating (see above)
- and the parent of the instruction is a switch statement.
