There are several things to be concerned about here that might require
different testing approaches:
- compiler's conformance to the C++ ABI specification
- consistency of code and externally visible symbols generated by the
compiler, right or wrong
- interoperability between GCC and proprietary compilers, including
platforms that use a different formal C++ ABI specification
- consistency of libstdc++, for which there is no formal ABI
specification
When will you be able to tell us more about the C++ ABI test suite that
CodeSourcery is developing? If it's possible that it won't be open
then we might want to duplicate some of its coverage in tests that will
be available to all GCC developers.
