title: I'm missing methods in Mach-O 64bit disassembly, why?
body: <p>I'm curious why when I disassemble my own program which is a fat binary (using otx), once for the i386 arch, and again for the x86_64 arch - I cannot find certain methods which are contained in the i386?</p>
  
  <p>For instance the disassembly for a method isAvailable would appear in its entirety under the i386 disasm but not under the x64...?  Ideas why?  Am I missing a basic understanding of Mach-O structure?</p>
  
  <p>Thanks!</p>
