some of those issues come up even more forcefully when cross compiling from a 64bit to 32 bit architecture :), but you're absolutely right, and It sounds like theres a clear near term concensus
Even more fun is in the case of ghc-ios, where ideally a single build would create the right object code for 64bit + 32bit arm both! I think theres some subtle fun there! :) On Tue, Jan 14, 2014 at 4:12 PM, Sven Panne <svenpa...@gmail.com> wrote: > 2014/1/14 Carter Schonwald <carter.schonw...@gmail.com>: > > I emphatically and forcefully agree with Isaac.
