Committed.

Next, I will do member_data.exp and member_data_static.exp.

I'm not sure if there is a spot of confusion here.  The new try_catch.exp test
PASSes all its tests with all the compilers I tested (g++ v2 and g++ v3).

In the long run, I'd like to get access to an hpux machine for my testing
project, but that's not even on my TODO list yet.

Re: gdb.c++ testsuite 2.1: try_catch.exp

[Michael Elizabeth Chastain]

There was a cut-and-paste error here (line 122 versus line 118):

  send_gdb "break 122\n"
  gdb_expect {
     -re "Breakpoint \[0-9\]*.*line 118\\.\r\n$gdb_prompt $" {
     ...

I rewrote all the send_gdb/gdb_expect pairs to gdb_test.
This simplifies the test script a lot:

  gdb_test "break 61" "Breakpoint \[0-9\]*.*line 61\\."
  gdb_test "continue" "Continuing\\.\r\n\r\nBreakpoint.*at.*try_catch\\.cc:61\r\n.*" "continue to 61"

As a side note, all test names within a test script must be unique to
facilitate comparing test runs against each other.  That's why gdb_test
"continue" has a third argument, so that I don't get a bunch of tests
all named "continue".  Your original script does this correctly; I'm
just mentioning it.

The actual tests are very simple.  They don't test any of the try/catch
functionality in gdb, just the control flow of the target program.
A simple test is better than no test; someone can add more tests to
this later.

All the tests pass in all the configurations that I tested:

  target  = native
  host    = i686-pc-linux-gnu%rh-7.2
  gdb     = 5.2, gdb_5_2-branch%20020526, HEAD
  gcc     = 2.95.3, 2.96-rh, 3.0.4, 3.1, gcc-3_1-branch%20020526, HEAD%20020526
  glibc   = vendor
  goption = -gdwarf2, -gstabs+

I build all my gcc's with --disable-shared.  So if there is a bug with
shared gcc libraries, then I won't see it.

Here is the revised version of try_catch.exp.  I will commit this shortly.

Looks good, thanks for your additions.

Right. Actually, this has not worked in the past, so I thought it'd be
best to start with the basics.

Great.

Try it using HP'x C++ compiler.  The re-vamped mechanism came in as part 
of the HP merge so should have at least worked there.

If anything still works there.  No one's tested aCC for quite a long
time now, and I still haven't found access to a version of HP/UX that
has aCC and GDB can handle.

gdb.c++ testsuite 2.1: try_catch.exp

[Benjamin Kosnik]

tested x86/linux. This test also current fails for shared builds,
although stepping through it with the static binary seems fine.
