Some DWARF internals are exposed for the needs of DWARF-based debug formats.
Each DIE attribute has a field specifying the attribute kind, a link to the next attribute in the chain, and an attribute value. Attributes are typically linked below the DIE they modify.

◆ mem_loc_descriptor()
|
extern |
The following routine converts the RTL for a variable or parameter (resident in memory) into an equivalent Dwarf representation of a mechanism for getting the address of that same variable onto the top of a hypothetical "address evaluation" stack. When creating memory location descriptors, we are effectively transforming the RTL for a memory-resident object into its Dwarf postfix expression equivalent. This routine recursively descends an RTL tree, turning it into Dwarf postfix code as it goes. MODE is the mode that should be assumed for the rtl if it is VOIDmode. MEM_MODE is the mode of the memory reference, needed to handle some autoincrement addressing modes. Return 0 if we can't represent the location.
