/* Helper file for declaring TCG helper functions.
|
|
Used by other helper files.
|
|
|
|
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.
