+/* As of 2004-01-17 only the 32-bit SPARC ABI has been identified as an
+ ABI suitable for the implementation of a robust extract
+ struct-convention return-value address method (the sparc saves the
+ address in the callers frame). All the other cases so far examined,
+ the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
+ erreneous - the code was incorrectly assuming that the return-value
+ address, stored in a register, was preserved across the entire
+ function call.
+ For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
+ the ABIs that are still to be analyzed - perhaps this should simply
+ be deleted. The commented out extract_returned_value_address method
+ is provided as a starting point for the 32-bit SPARC. It, or
+ something like it, along with changes to both infcmd.c and stack.c
+ will be needed for that case to work. NB: It is passed the callers
+ frame since it is only after the callee has returned that this
+ function is used.
