Validating a C++ back-end

[Vasanth <geekvasanth at gmail dot com>]

Hi,

I am working on a fresh C++ port and I am filling in all the machine
specific hooks.

How do I run the C++ testsuite on my compiler? I am familiar with the
GCC torture/execute tests and have my backend passing those tests
reasonably well. Now, I am looking for something similar for C++ to
test my support for the language's features.

I am a bit confused by how the Deja Gnu tests are organized. I see
that the testsuite contains a lot of different tests of which, some
are compile only tests, some are pre-processor tests etc. Aren't the
"runnable" tests the main kind that I should be interested in? Given a
compiler version of 3.x.x shouldn't I be able to rely on test results
run on the generic portions by the GCC maintainers themselves and
worry about only the runnable tests?

Is there a specific/sufficient list of tests that I need to validate...?

Please let me know if I am missing something...

thanks,
Vasanth
