A small testcase to reproduce would be useful to understand what you are
talking about.  Are you using register or asm("register")?  Is this a local
or global?  What target are you compiling for?  What compiler options are
you using?  What debug info format are you using?  Dwarf, stabs?  Why do
you think the debug info is missing?  Can you show some gdb output?  If you
are using stabs, then that is probably why it is failing for you.  Use
dwarf instead.
