From d0567dc0dbf92258aaea727b7b93a7d8bc954e33 Mon Sep 17 00:00:00 2001 From: Pierre-Marie de Rodat Date: Thu, 9 Nov 2017 10:24:45 +0000 Subject: [PATCH] [multiple changes] 2017-11-09 Jerome Lambourg * sigtramp-qnx.c: Fix obvious typo. 2017-11-09 Doug Rupp * libgnarl/s-taprop__linux.adb (Monotonic_Clock): Minor reformatting. 2017-11-09 Ed Schonberg * sem_res.adb (Resolve): If expression is an entity whose type has implicit dereference, generate reference to it, because no reference is generated for an overloaded entity during analysis, given that its identity may not be known. 2017-11-09 Javier Miranda * exp_disp.adb (Expand_Interface_Thunk): Replace substraction of offset-to-top field by addition. (Make_Secondary_DT): Initialize the offset-to-top field with a negative offset. * exp_ch3.adb (Build_Offset_To_Top_Function): Build functions that return a negative offset-to-top value. (Initialize_Tag): Invoke runtime services Set_Dynamic_Offset_To_Top and Set_Static_Offset_To_Top passing a negative offet-to-top value; initialize also the offset-to-top field with a negative offset. * libgnat/a-tags.adb (Base_Address): Displace the pointer by means of an addition since the offset-to-top field is now a negative value. (Displace): Displace the pointer to the object means of a substraction since it is now a negative value. (Set_Dynamic_Offset_to_top): Displace the pointer to the object by means of a substraction since it is now a negative value. 2017-11-09 Eric Botcazou * gnat1drv.adb (Gnat1drv): Call Errout.Finalize (Last_Call => True) before Errout.Output_Messages also in the case of compilation errors. 2017-11-09 Javier Miranda * doc/gnat_ugn/the_gnat_compilation_model.rst (Interfacing with C++ at the Class Level): Fix error interfacing with C strings. * gnat_ugn.texi: Regenerate. 2017-11-09 Jerome Lambourg * system-qnx-aarch64.ads: Fix the priority constants. * s-osinte__qnx.ads: Fix constants for handling the locking protocols and scheduling. * s-osinte__qnx.adb: New file , prevents the use of priority 0 that corresponds to an idle priority on QNX. 2017-11-09 Piotr Trojanek * sem_prag.adb, sem_util.adb, sem_elab.adb: Fix minor typos in comments.
