Can you elaborate on why MCJIT TLS support needs code in the low 2 GB? What piece of data do you need to be reachable? It sounds like this was discussed on IRC, but I'm curious. Does the MCJIT even have the reachability problems of the old JIT? If you build an object file in memory, presumably you can measure it and then allocate +x memory for it all at once, instead of the old model of

Hi David, I believe that assertion indicates that something didn't get loaded into the lower 2GB of address space. That is, the memory manager isn't allocating memory in that range. I'm sure there must be a way to allocate memory in that range on FreeBSD. The system loader has to do it, right? I just don't know what makes it happen. -Andy -----Original Message----- From: Dr
