Bug ID: 25132
Summary: Calculate die_ref_hash lazily
Product: dwz
Version: unspecified
Status: NEW
Severity: enhancement
Priority: P2
Component: default
Assignee: nobody at sourceware dot org
Reporter: vries at gcc dot gnu.org
CC: dwz at sourceware dot org
Target Milestone: ---
Idea for optimization.
We compare dies for equality if the die_ref_hash matches.
However, it may not be necessary to calculate the die_ref_hash for all dies.
If the die_hash for two dies doesn't match, we don't need to calculate the
die_ref_hash for those.
This won't work when f.i. collapsing dies, since we need to keep the dies
around.
