From 760732e434d89dcbdedbf74777ad88bd3f5e51f5 Mon Sep 17 00:00:00 2001 From: charlet Date: Fri, 28 Apr 2017 13:29:34 +0000 Subject: 2017-04-28 Hristian Kirtchev * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use New_Copy_Tree instead of Relocate_Node as any subsequent copies of the relocated node will have mangled Parent pointers. * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash tables used in conjunction with entity and itype replication. (Visit_Entity): Rewrite the restriction on which entities require duplication.
