From: Arnaud Charlet Date: Tue, 25 Apr 2017 13:05:10 +0000 (+0200) Subject: [multiple changes] X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1f70c47f8a074151222103aa69b16375584d24a0;p=gcc.git [multiple changes] 2017-04-25 Hristian Kirtchev * sem_util.adb (Is_Post_State): A reference to a generic in out parameter is considered a change in the post-state of a subprogram. 2017-04-25 Ed Schonberg * sem_ch12.adb (Load_Parent_Of_Generic); When retrieving the declaration of a subprogram instance within its wrapper package, skip over null statements that may result from the rewriting of ignored pragmas. 2017-04-25 Ed Schonberg * exp_attr.adb (Expand_Attribute_Reference, case 'Read): If the type is an unchecked_union, replace the attribute with a Raise_Program_Error (rather than inserting such before the attribute reference) to handle properly the case where we are processing a component of a larger record, and we need to prevent further expansion for the unchecked union. (Expand_Attribute_Reference, case 'Write): If the type is an unchecked_union, check whether enclosing scope is a Write subprogram. Replace attribute with a Raise_Program_Error if the discriminants of the unchecked_union type have not default values because such a use is erroneous.. 2017-04-25 Tristan Gingold * exp_ch9.adb (Expand_N_Task_Type_Declaration): Add relative_deadline to task record on edf profile. (Make_Initialize_Protection): Pass deadline_floor value on edf profile. (Make_Task_Create_Call): Pass relative_deadline value. * par-prag.adb (Prag): Handle Pragma_Deadline_Floor. * s-rident.ads (Profile_Name): Add GNAT_Ravenscar_EDF. (Profile_Info): Add info for GNAT_Ravenscar_EDF. * sem_prag.adb (Set_Ravenscar_Profile): Handle GNAT_Ravenscar_EDF (set scheduling policy). (Analyze_Pragma): Handle GNAT_Ravenscar_EDF profile and Deadline_Floor pragma. (Sig_Flags): Add choice for Pragma_Deadline_Floor. * snames.ads-tmpl (Name_Deadline_Floor, Name_Gnat_Ravenscar_EDF): New names. (Pragma_Deadline_Floor): New pragma. * targparm.adb (Get_Target_Parameters): Recognize GNAT_Ravenscar_EDF profile.
