Can we have a more extensive comment here? What are symbols that begin with ".objc_"? Why should we ignore them? Where can we find more complete documentation for what they mean? (Is there any document that describes how Objective C programs are represented at the assembly/linkage level?) Michael Snyder <msnyder@redhat.com> writes:Adam Fedor wrote:Jim, could you take a quick look at this small change?This patch adds Objective-C language support to gdb based upon a patch provided by Apple Computer Inc from their version of gdb. Note that the patch only contains changes to existing files. New files (objc-lang.h, objc-lang.c, objc-exp.y) and a gdb.objc testsuite directory are located at ftp://ftp.gnustep.org/pub/gnustep/contrib/gdb-objc-patch.tar.gz
