From 59e9bc0b6ff7d00bd56a5b4767014b6529bf820b Mon Sep 17 00:00:00 2001 From: Arnaud Charlet Date: Tue, 6 Jan 2015 11:22:41 +0100 Subject: [multiple changes] 2015-01-06 Ed Schonberg * sem_ch12.adb: Sloc of wrapper is that of instantiation. 2015-01-06 Robert Dewar * sem_ch11.adb: Minor reformatting. 2015-01-06 Ed Schonberg * exp_aggr.adb (Get_Assoc_Expr): New routine internal to Build_Array_Aggr_Code, used to initialized components covered by a box association. If the component type is scalar and has a default aspect, use it to initialize such components. 2015-01-06 Pascal Obry * rtinit.c (__gnat_runtime_initialize): Add a parameter to control the setup of the exception handler. * initialize.c: Remove unused declaration. * bindgen.adb: Always call __gnat_runtime_initialize and pass whether the exeception handler must be set or not.
