Hi, I am facing some trouble in G++'s Exception Handling(EH) implementation of GCC CR16C port . During branching to the called function, the return address of the next instruction right shifted by 1 is stored in the RA(Return Address) register. This is a hardware implementation. The DWARF information generated for EH has found to be storing this right shifted return value appropriately. To my knowledge , debugging information for variables and stack pushed registers was generated correctly. How can I communicate to DWARF EH regarding the right shifted value of return address. How can I do this in backend code? I am using the 'stack unwinder' mechanism to restore the register values. I have taken reference of following wiki link to verify EH implementation: http://gcc.gnu.org/wiki/Dwarf2EHNewbiesHowto Gcc Version: 4.5.1 Any pointers on this issue are highly appreciated. Regards, Sumanth
