title: Error compiling NEON for iOS 5.1 with clang integrated assembler
body: <p>I try to compile NEON assembly code with LLVM clang integrated macro assembler (the LLVM compiler shipped with XCode 4.3) and get the following error:</p>
  
  <pre><code>vld1.8 {D0}, [R0] - invalid operand for instruction
  </code></pre>
  
  <p>What can be the reason? Why this instruction is successfuly compiled by GAS for Android and can't be compiled by 'clang -integrated-as ...' for iOS? Thanks.</p>
