#### 6.56.1 ARM Pragmas

The ARM target defines pragmas for controlling the default addition of `long_call` and `short_call` attributes to functions. See Function Attributes, for information about the effects of these attributes.

`long_calls`
  Set all subsequent functions to have the `long_call` attribute.
`no_long_calls`
  Set all subsequent functions to have the `short_call` attribute.
`long_calls_off`
  Do not affect the `long_call` or `short_call` attributes of subsequent functions.
