--- Comment #4 from David Binderman <dcb314 at hotmail dot com> --- Roger makes an interesting comment about test case coverage in the C and C++ testsuite. There are about 45,000 C test cases and about 19,000 C++ test cases. This gives pretty good coverage in practice, with only occasional problems failing to be found. The much stronger test of compiling an entire Linux distribution on x86_64, which I do most weeks, generates about 340,000 object modules, so it is a far bigger and more comprehensive testcase. It would be an obvious extension to compile a Linux distribution on a different architecture. Maybe ARM or PowerPC or another primary gcc target ?
