Simply, clang has an option '--no-integrated-as' so that the compiler invokes apple’s standalone 'as' assembler instead of using clang’s built-in. But, either has its own lost pieces.

  • Without '--no-integrated-as', clang would use its internal assembler. Unfortunately it doesn’t recognize the mnemonic 'ldmltfd'
  • With '--no-integrated-as', apple’s 'as’ assembler reports an error in pesudo instruction '.ios_version_min', which was apparently generated by clang itself.

Therefore I have no choice except for changing 'ldmltfd' to two simple instructions…

  • Replaced ‘ldmltfd’ with 2 iinstructions: ‘beq’ and ‘ldmfd’
