Yes and no:
* the DWARF standard itself does not specify any calling conventions other than DW_CC_normal (ABI default), DW_CC_program (Fortran-specific) and DW_CC_nocall (e.g. for interrupt handlers)
* however, the DWARF standard allows implementation-defined specific calling conventions to be added. I'm not aware of many that have been defined like that already, but a couple of them have been. E.g., search for DW_CC_ in . You need tool chain support (usually compiler support) to be able to generate such custom attributes though.
