The interface allows control over 29-- the destination of the output, so that this routine can also be used for 30-- debugging purposes. 31 32with Types; use Types; 33 34generic 35 -- The following procedures are used to output text information. The 36 -- destination of the text information is thus under control of the 37 -- particular instantiation. In particular, this procedure is used to 38 -- write output to the ALI file, and also for debugging output. 39 40 with function Write_Info_Col return Positive is <>; 41 -- Return the column in which the next character will be written 42 43 with procedure Write_Info_Char (C : Character) is <>; 44 -- Output one character 45 46 with procedure Write_Info_Initiate (Key : Character) is <>; 47 -- Initiate write of new line to output file, the parameter is the 48 -- keyword character for the line. 49 50 with procedure Write_Info_Nat (N : Nat) is <>; 51 -- Write image of N to output file with no leading or trailing blanks 52 53 with procedure Write_Info_Terminate is <>; 54 -- Terminate current info line and output lines built in Info_Buffer 55 56procedure Put_SPARK_Xrefs; 57-- Read information from SPARK tables (SPARK_Xrefs.SPARK_Xref_Table, 58-- SPARK_Xrefs.SPARK_Scope_Table and SPARK_Xrefs.SPARK_File_Table) and output 59-- corresponding information in ALI format using the Write_Info procedures. 60
