   8 MCORE Function Attributes
   9 ^^^^^^^^^^^^^^^^^^^^^^^^^
  10
  11 These function attributes are supported by the MCORE back end:
  12
  13 .. index:: naked function attribute, MCORE
  14
  15 .. mcore-fn-attr:: naked
  16
  17   This attribute allows the compiler to construct the
  18   requisite function declaration, while allowing the body of the
  19   function to be assembly code. The specified function will not have
  20   prologue/epilogue sequences generated by the compiler. Only basic
  21   ``asm`` statements can safely be included in naked functions
  22   (see :ref:`basic-asm`). While using extended ``asm`` or a mixture of
  23   basic ``asm`` and C code may appear to work, they cannot be
  24   depended upon to work reliably and are not supported.
