Re: [Dwarf-Discuss] Segment selectors for the range list table.

Anyone know of any existing DWARF producers that use segmented addressing? Might be interesting to see how they're using the features. On Thu, Jul 16, 2020 at 9:30 AM Michael Eager wrote: > On 7/15/20 9:49 PM, David Blaikie wrote: > > > > > > On Wed, Jul 15, 2020 at 7:07 PM Michael Eager via Dwa

Re: [Dwarf-Discuss] Segment selectors for the range list table.

Perhaps it's more like Paul was postulating - that the spec assumes code is in a code segment/doesn't need to be clarified. (but that gets a bit confused in debug_aranges - if it only is meant to contain code (not data), why does it need a segment selector - and also in the DIEs - if code is al

Re: [Dwarf-Discuss] Segment selectors for the range list table.

Segmented addresses have been in the DWARF specification since Version 2 and AFAIK have not been changed since that time. DWARF V5 did not add any functionality to segmented addresses that was not present in DWARF V2/3. At least, there was no intention to do so. Segmented addresses are desc

Looking at how segment selectors work: DW_AT_segment: Applies to a DIE subtree, including any ranges, high/low pc, locations, labels, etc debug_range/loc (v4 and below): Doesn't seem to allow specifying segment variation - inherits from the segment given on the nearest parent DIE that refers to th
