Bug ID: 88894
Summary: [libbacktrace] share abbrevs between units
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libbacktrace
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
CC: ian at gcc dot gnu.org
Target Milestone: ---
For each compilation unit we parse in build_address_map, we call read_abbrevs,
to parse the abbrevs, and store the parsed representation in memory.
However, multiple compilation units can share the same abbrev offset, and in
the current setup we would parse and store such an abbrev twice, which is
inefficient.
