From 029d22004062d6f79918c80bd69cda08d00b7d51 Mon Sep 17 00:00:00 2001 From: Andrew Cagney Date: Fri, 16 Jul 2004 22:21:52 +0000 Subject: [PATCH] 2004-07-16 Andrew Cagney * gdb.base/restore.c: Append "prologue" to comments marking the a function's prologue. * gdb.base/restore.exp: Update copyright, re-indent. (restore_tests): Use gdb_test_multiple. Add "calleeN calls callerN" prefix where needed.
