From: Arnaud Charlet Date: Wed, 3 Aug 2011 14:54:24 +0000 (+0200) Subject: [multiple changes] X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1cdfa9be54975f0566d6f261a706dcb8d767601d;p=gcc.git [multiple changes] 2011-08-03 Hristian Kirtchev * exp_ch7.adb (Create_Finalizer): Treat freeze nodes in similar fashion to packages. This ensures that the finalizer body will not end up inside the freeze node. (Process_Declarations): Add code to detect whether a freeze node has a nested finalization collection. 2011-08-03 Pascal Obry * g-awk.adb, g-awk.ads: Make GNAT.AWK API compatible with Ada 2005. (Current_Session): Return a not null access to Session_Type. (Default_Session): Likewise.
