We are using GCC 3.3.1 and have a requirement imposed upon us by our customer to "...establish that the C++ compiler implements dynamic binding by utilizing static lookup tables..."
The short answer is "yes, GCC uses static lookup tables for dynamic binding". But don't take that as anything more than an educated opinion, and certainly not certification.
Given all this, I posed this question to the gcc mailing list and received a reply that directed me to the C++ ABI (http://codesourcery.com/cxx-abi/), which is more detailed and has the information I'm looking for. However, I need to confirm, in the case of an FAA audit, that GCC 3.3.1 implements dynamic binding in this fashion. Can anyone on the steering committee "officially" confirm that GCC uses static v-tables as described in the ABI?
You should read the GPL license (http://www.gnu.org/copyleft/gpl.html) under which GCC is distributed. In particular see Paragraph 11, under the large heading "NO WARRANTY". I question whether you will find anyone who would be willing to affirm that GCC has any specific behavior if such a certification were intended to provide a guarantee or warranty, or if there was any expectation that there was any assumption of liability for GCC's failure to perform as indicated. -- Michael Eager [EMAIL PROTECTED] 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077
