From 94ce49419aef75f3414edcaeba89e63c6c3be320 Mon Sep 17 00:00:00 2001 From: Hristian Kirtchev Date: Thu, 11 Jan 2018 08:51:13 +0000 Subject: [Ada] Encoding of with clauses in ALI files This patch modifies the encodings of with clauses in ALI files to adhere to the existing API. The encodigs are as follows: * Explicit with clauses are encoded on a 'W' line (same as before). * Implicit with clauses for ancestor units are encoded on a 'W' line (same as before). * Limited_with clauses are encoded on a 'Y' line (same as before). * ABE and RTSfind-related with clauses are encoded on a 'Z' line. ------------ -- Source -- ------------ -- case_10_func.adb function Case_10_Func return Boolean is begin return True; end Case_10_Func; -- case_10_gen_func.ads generic function Case_10_Gen_Func return Boolean; -- case_10_gen_func.adb function Case_10_Gen_Func return Boolean is begin return True; end Case_10_Gen_Func; -- case_10_tasks.ads package Case_10_Tasks is task type Task_Typ is end Task_Typ; end Case_10_Tasks; -- case_10_tasks.adb package body Case_10_Tasks is task body Task_Typ is begin null; end Task_Typ; end Case_10_Tasks; -- case_10_gen.ads with Case_10_Func; with Case_10_Gen_Func; with Case_10_Tasks; generic package Case_10_Gen is Val : constant Boolean := Case_10_Func; function Inst is new Case_10_Gen_Func; Tsk : Case_10_Tasks.Task_Typ; end Case_10_Gen; -- case_10.ads with Case_10_Gen; package Case_10 is package Inst is new Case_10_Gen; end Case_10; ---------------------------- -- Compilation and output -- ---------------------------- $ gcc -c case_10.ads $ grep "W " case_10.ali | sort $ grep "Z " case_10.ali | sort W case_10_gen%s case_10_gen.ads case_10_gen.ali Z case_10_func%b case_10_func.adb case_10_func.ali Z case_10_gen_func%s case_10_gen_func.adb case_10_gen_func.ali ED Z case_10_tasks%s case_10_tasks.adb case_10_tasks.ali AD Z system.soft_links%s s-soflin.adb s-soflin.ali Z system.tasking%s s-taskin.adb s-taskin.ali Z system.tasking.stages%s s-tassta.adb s-tassta.ali 2018-01-11 Hristian Kirtchev gcc/ada/ * ali.adb: Document the remaining letters available for ALI lines.

Add field Implicit_With. * csinfo.adb (CSinfo): Remove the setup for attribute Implicit_With_From_Instantiation. * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as either implicitly or explicitly withed. (Is_Implicit_With_Clause): New routine. (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid confusion with the with clause attribute by the same name. (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers. * rtsfind.adb (Maybe_Add_With): Code cleanup. * sem_ch8.adb (Present_System_Aux): Code cleanup. * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated for a parent unit. (Implicit_With_On_Parent): Mark the with clause as generated for a parent unit. * sem_ch12.adb (Inherit_Context): With clauses inherited by an instantiation are no longer marked as Implicit_With_From_Instantiation because they are already marked as implicit. * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge which marks implicit with clauses as related to an instantiation. * sinfo.adb (Implicit_With_From_Instantiation): Removed. (Parent_With): New routine. (Set_Implicit_With_From_Instantiation): Removed. (Set_Parent_With): New routine. * sinfo.ads: Update the documentation of attribute Implicit_With. Remove attribute Implicit_With_From_Instantiation along with occurrences in nodes. Add attribute Parent_With along with occurrences in nodes. (Implicit_With_From_Instantiation): Removed along with pragma Inline. (Parent_With): New routine along with pragma Inline. (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline. (Set_Parent_With): New routine along with pragma Inline.
