For Linux systems is the first global variable allocated at 0x10000

Hello,

I was looking over the dataflow sanitizer and though the method with which it allocates memory is quite clever I find it somewhat unappealing in certain cases since it seems to convert the move the addr values from the original locations using a runtime mask calculation from the old value. I am wondering if in my use case for generating a fast shadow if I could allocate something as the first global in the global table and if that would be guaranteed to map to the bottom of memory. Is this the case?

Thanks in advance,

Carter.
