[fpc-devel] Compiler limitations
Hi Folks, according the documentation Arrays are limited to 2 GBytes in size in the default processor mode. Is there another mode allowing bigger arrays? Cheers, miklos ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
Re: [fpc-devel] Compiler limitations
What about iterators, linked lists ? You can use them some of them. You can also create a temporary file that built in a way that you understand it as an array. there are many ways to do work around over this issues. I yet found a good reason to have such a big data for array. It's bed practice. you should use either iterators or linked list (while many times iterators are better).

Things like type ta = array[0..$f] of byte; var p : ^ta; begin new(p); end. should work e.g. on linux. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

Has sb meanwhile crafted an executable on win64 that actually uses 2GB ? ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
