All you need is to make sure that gdb_target_obs is the same list of objects before and after the patch. So you could drop this script in gdb/ , and call it for each for the triplets above, before and after the patch, and diff the output. ~~~ $ cat test-configure.tgt set -e targ=$1 if [ $targ == "" ]; then echo "no target specified" exit 1 fi source ./configure.tgt echo "target: $targ" objs=$(echo $gdb_target_obs | sort -u) echo "gdb_target_obs: $objs" ~~~ $ ./test-configure.tgt i686-unknown-linux-gnu target: i686-unknown-linux-gnu gdb_target_obs: i386-tdep.o i386.o i386-linux-tdep.o glibc-tdep.o i387-tdep.o solib-svr4.o symfile-mem.o linux-tdep.o linux-record.o That's going to be way faster... Might be worth it to add something like this to the tree. Thanks, Pedro Alves
