[RFA] testsuite/gdb.c++/ref-types.exp: use runto

This is Sunday Project Patch #5 (try #2). This is unchanged from
the previous version, submitted 2001-02024, which received no response.
gdb.c++/ref-types.exp has several places with control logic like this:
send_gdb "break marker1\n" ; gdb_expect -re ".*$gdb_prompt $"
send_gdb "cont\n"
gdb_expect {
-re "Break.* marker1 \\(\\) at .*:$decimal.*$gdb_prompt $" {
send_gdb "up\n"
gdb_expect {
-re ".*main.*$gdb_prompt $" {
pass "up from marker1"
}
-re ".*$gdb_prompt $" {
fail "up from marker1"
}
timeout { fail "up from marker1 (timeout)" }
}
}
-re "$gdb_prompt $" { fail "continue to marker1" }
timeout { fail "(timeout) continue to marker1" }
}
With FSF g++ v3, I am getting output like this:
Breakpoint 2, marker1() () at /vittone/fsf/2001-02-21/source-src/gdb/testsuite/gdb.c++/ref-types.cc:6
6 }
(gdb) FAIL: gdb.c++/ref-types.exp: continue to marker1
So the test script never issues the "up" command, the test script goes
off the rails, and every test FAILs.
The "marker1() ()" output is a v3 bug and I have filed PR gdb/34 about it.
This patch changes the test script to:
if ![runto 'marker1'] then {
perror "couldn't run to marker1"
continue
}
gdb_test "up" ".*main.*" "up from marker1"
... which is shorter and cleaner anyways. This enables the test script
to run its real tests, which proceed to PASS. This fixes 60 FAILs,
leaving no FAILs for this test script.
Testing: tested on Red Hat Linux 6.2 native and Solaris 2.6 native with
g++ v2 and g++ v3.
OK to apply?
