544 | For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of | |
545 | the ABIs that are still to be analyzed - perhaps this should simply | |
546 | be deleted. The commented out extract_returned_value_address method | |
547 | is provided as a starting point for the 32-bit SPARC. It, or | |
548 | something like it, along with changes to both infcmd.c and stack.c | |
549 | will be needed for that case to work. NB: It is passed the callers | |
550 | frame since it is only after the callee has returned that this | |
551 | function is used. | |

0f79675b AC |
1007 | |
