How is the debugging information stored in the WHIRL and passed to back end?

The debugging information is stored in the form of DST (for Debug 

Symbol Table), which has its own section in the .B file produced by 

the front-end. You can see this DST section via "ir_b2a -st foo.B". 

This section contains more information when the compilation has -g. 

The backend builds the dwarf debugging information from the DST info, 

which contains cross-references to the WHIRL symbol tables.
