Since GNU binutils version 2.44, assembly functions must include the assembler directive .type name, %function. If not a call to these functions fails with the error message 'Unknown destination type (ARM/Thumb)' and the error message 'dangerous relocation: unsupported relocation' at linking.
The macros ENTRY/ENDPROC includes this directive and should be used for all assembly functions.
