+# 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.
