1279 | + Create a stack frame, setup an argument context, call the callee | ||
1280 | + and extract the result. | ||
1281 | + | ||
1282 | + The maximum required argument stack size is provided, | ||
1283 | + ffi_call_SYSV() allocates that stack space then calls the | ||
1284 | + prepare_fn to populate register context and stack. The | ||
1285 | + argument passing registers are loaded from the register | ||
1286 | + context and the callee called, on return the register passing | ||
1287 | + register are saved back to the context. Our caller will | ||
1288 | + extract the return value from the final state of the saved | ||
1289 | + register context. | ||
