| /* Atomic built-in C functions for link compatibility with older code that |
| was compiled to emit function calls for atomic built-ins. |
| Notice that if no atomic model has been selected the functions in this |
| file must not be generated, or else they will result in infinite no-op |
| loops. |
| Notice also, that all the generated functions below take three parameters, |
| which is not actually true for some of the built-in functions. However, |
| on SH this does not matter, since the first four parameters are always |
| passed in call clobbered registers. |
| The return type for the sync_bool_compare_and_swap functions is also |
| actually supposed to be a bool, but this also doesn't matter since any |
| int return type <= 32 bit is returned in R0 on SH. */ |
