From 041ab88cf047ecfa2c5c7421ab3976c9dcb6646a Mon Sep 17 00:00:00 2001 From: Michael Chastain Date: Fri, 9 Jan 2004 09:48:52 +0000 Subject: [PATCH] 2004-01-09 Michael Chastain * gdb.cp/exception.cc: Change to . * gdb.cp/exception.exp: Use gdb test, gdb_test_multiple. Use gdb_compile. Remove restriction on gcc. Add some patterns for recent version of gdb. Delete second half, which was a copy of the first half with different build flags.
