dwarf2 loclist question

[Dhananjay R. Deshpande]

Hi,

The third party debugger I am using requires DW_AT_return_addr be generated for subroutines. It uses this for stack trace. The return address location can be specified correctly only by loclist. The return address location before prologue, after prologue and  at epilogue will be different. 

Any idea if recent var tracking pass can be used for this? 

Regards,
