REGCONFLICT

Message        Conflicting required uses of register(s):  <text>

Description    The special linkage associated with a function has
               specified that one of the standard calling convention
               registers be used in a nonstandard way without also
               replacing its standard use with another register.  An
               example would be a function that returns an int value
               using a special linkage that states R0 is not used,
               and does not specify another register to hold the
               return value.

User Action    Correct the #pragma linkage directive that specifies
               the special linkage.
