cmake_minimum_required(VERSION 3.4)
project(2ine)
# Note that this project doesn't work on Mac OS X because I can't mmap()
# address 0x10000, which is the usual base address for OS/2 binaries.
# It appears the address is already accessible when main() begins, but no
# objects seem to be loaded there. I don't know what it is...maybe some
# thing allocated by the C runtime at startup? Have to solve that somehow or
# give up on Mac support.
#
# Eventually, even on Linux, it might make sense to override malloc and friends
# at the dynamic loader level, so we control all allocations even if they
# happen in glibc. Once we have that, make sure they all sit in the upper
# 2 gigabytes (reserved for system use on OS/2, so this works out), probably
# with them mmap()'d there via a local copy of dlmalloc or something.
#
# Note that 32-bit OS/2 programs only got 512 megabytes of the address space
# (enormous in the days of machines with a couple megabytes of physical RAM!)
# to accomodate thunking to and from 16 bit code. We don't bother with this
# at the moment, though, but maybe we must at some point. I hope not.
#
# Also, it might be nice if we can run as a 64-bit process and thunk around in
# 32-bits as necessary, but I don't know the technical barriers to this yet.
# If we can pull that off, it would allow an OS/2 app to have the full 4
# gigabytes of memory, and we'll just put 2ine's data outside of that range,
# and run the native bits with more registers, etc. Maybe even keep the
# native functions out of low memory and only eat a few bytes of it with
# trampolines. I'm probably getting ahead of myself, though, as it's not like
# any OS/2 apps were _that_ memory hungry, and honestly? Port your software.
