I noticed a different address space layout for an app (i.e. vi) on different platforms (see below). is ELF allowing for what I notice on T1000/T2000 platforms (.text segment "split") and 2 extra "anon" pages? may I know the rationale behind (i.e. is that machine-specific)? is there in OpenSolaris.com, same source code that I can walk to better understand?
