-/* Helper file for declaring TCG helper functions.
- Should be included at the start and end of target-foo/helper.h.
-
- Targets should use DEF_HELPER_N and DEF_HELPER_FLAGS_N to declare helper
- functions. Names should be specified without the helper_ prefix, and
- the return and argument types specified. 3 basic types are understood
- (i32, i64 and ptr). Additional aliases are provided for convenience and
- to match the types used by the C helper implementation.
-
- The target helper.h should be included in all files that use/define
- helper functions. THis will ensure that function prototypes are
- consistent. In addition it should be included an extra two times for
- helper.c, defining:
- GEN_HELPER 1 to produce op generation functions (gen_helper_*)
- GEN_HELPER 2 to do runtime registration helper functions.
