From 62253a61473764b0d084b01eff06a93fb38bb2e3 Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Thu, 11 Apr 2019 23:51:48 +0100 Subject: gdb: Remove LANG_MAGIC The language_defn structure has an la_magic field, this used to be used as a basic check that the language_defn structure had the expected layout - at least the end of the structure was where we expected it to be. This feature only really makes sense if we imagine GDB dynamically loading language support from dynamic libraries, where a version mismatch might cause problems. However, in current GDB language support is statically built into GDB, and since this commit: commit 47e77640be31fc1a4eb3718f594ed5fd0faff065 Date: Thu Jul 20 18:28:01 2017 +0100 Make language_def O(1) the existing (if pointless) check of the la_magic field was removed. There now appears to be no use of the la_magic field, and I propose that we delete it. There should be no user visible changes after this commit. gdb/ChangeLog: * ada-lang.c (ada_language_defn): Remove use of LANG_MAGIC. * c-lang.c (c_language_defn): Likewise.
