241 Return the pointer to the first instruction of a function given a function pointer.
242 For Itanium CPUs, all function calls are made through a PLABEL, so a pointer to a function
243 is actually a pointer to a PLABEL. The pointer to the first instruction of the function
244 is contained within the PLABEL. This macro may be used to retrieve a pointer to the first
245 instruction of a function independent of the CPU architecture being used. This is very
246 useful when printing function addresses through DEBUG() macros.
248 @param FunctionPointer A pointer to a function.
250 @return The pointer to the first instruction of a function given a function pointer.
