helper-head.h (4606B)

      1/* Helper file for declaring TCG helper functions.
      2   Used by other helper files.
      3
      4   Targets should use DEF_HELPER_N and DEF_HELPER_FLAGS_N to declare helper
      5   functions.  Names should be specified without the helper_ prefix, and
      6   the return and argument types specified.  3 basic types are understood
      7   (i32, i64 and ptr).  Additional aliases are provided for convenience and
      8   to match the types used by the C helper implementation.
      9
     10   The target helper.h should be included in all files that use/define
     11   helper functions.  THis will ensure that function prototypes are
     12   consistent.  In addition it should be included an extra two times for
     13   helper.c, defining:
     14    GEN_HELPER 1 to produce op generation functions (gen_helper_*)
     15    GEN_HELPER 2 to do runtime registration helper functions.
