From: Ed Schonberg Date: Sun, 21 Jun 2020 16:58:55 +0000 (-0400) Subject: [Ada] Ada_2020: Add aspect Aggregate to standard container units X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fe3463cc9884e422f8d9147d2e8b5ef13e336aa6;p=gcc.git [Ada] Ada_2020: Add aspect Aggregate to standard container units gcc/ada/ * exp_aggr.adb (Expand_N_Aggregate): A record aggregate requires a non-private type. * sem_ch13.adb (Valid_Assign_Indexed): New subprogram local to Resolve_Aspect_Aggregate, to handle the case when the corresponding name appearing in the aspect specification for an indexed aggregate is an overloaded operation. * libgnat/a-convec.ads, libgnat/a-convec.adb, libgnat/a-coinve.ads, libgnat/a-coinve.adb, libgnat/a-cobove.ads, libgnat/a-cobove.adb, libgnat/a-cdlili.ads, libgnat/a-cdlili.adb, libgnat/a-cbdlli.ads, libgnat/a-cbdlli.adb, libgnat/a-cohama.ads, libgnat/a-cihama.ads, libgnat/a-cbhama.ads, libgnat/a-cborma.ads, libgnat/a-ciorma.ads, libgnat/a-coorma.ads, libgnat/a-cihase.ads, libgnat/a-cohase.ads, libgnat/a-cbhase.ads, libgnat/a-cborse.ads, libgnat/a-ciorse.ads, libgnat/a-coorse.ads: Add Ada_2020 aspect Aggregate to types declared in standard containers, as well as new subprograms where required. --- diff --git a/gcc/ada/exp_aggr.adb b/gcc/ada/exp_aggr.adb index 168a5923944..c24588a4ae7 100644 --- a/gcc/ada/exp_aggr.adb +++ b/gcc/ada/exp_aggr.adb @@ -6758,7 +6758,9 @@ package body Exp_Aggr is begin -- Record aggregate case - if Is_Record_Type (Etype (N)) then + if Is_Record_Type (Etype (N)) + and then not Is_Private_Type (Etype (N)) + then Expand_Record_Aggregate (N);
