+ * trans-io.c (enum iocall): Add IOCALL_X_INTEGER_WRITE,
+ IOCALL_X_LOGICAL_WRITE, IOCALL_X_CHARACTER_WRITE,
+ IOCALL_X_CHARACTER_WIDE_WRIE, IOCALL_X_REAL_WRITE,
+ IOCALL_X_COMPLEX_WRITE and IOCALL_X_ARRAY_WRITE.
+ (gfc_build_io_library_fndecls): Add corresponding function
+ decls.
+ (transfer_expr): If the current transfer is a READ, use
+ the iocall with the original version, otherwise the version
+ with _WRITE.
+ (transfer_array_desc): Likewise.
