Searching for info on ia64 turned up this interesting thread: https://www.postgresql.org/message-id/21563.1289064886%40sss.pgh.pa.us >From that discussion it seems we should probably run these tests with -O0 because the stack usage can be substantially higher without optimizations. And it doesn't sound like ia64 uses much more *normal* stack, just that there's the additional register stack. It might not be unreasonable to commit the pmap hack, gather the data from the build farm then later add an #ifdef around it. (or just make it #ifdef USE_ASSERTIONS which I assume most build farm members are running with anyways). Alternatively it wouldn't be very hard to use mincore(2) to implement it natively. I believe mincore is nonstandard but present in Linux and BSD. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
