Bug ID: 25753
Summary: Add note to add/removed functions that are in comdat
sections
Product: libabigail
Version: unspecified
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: default
Assignee: dodji at redhat dot com
Reporter: jwakely.gcc at gmail dot com
CC: libabigail at sourceware dot org
Target Milestone: ---
For C++ libraries a small code change or a slightly different compiler version
can alter inlining decisions, causing previously emitted functions to be
inlined and disappear from the generated code, causing abigail to report
removed functions. The opposite can also happen where previously inlined
functions start to be emitted, and abigail reports added functions.
If an added/removed symbol is in a comdat section, it probably means it's
inline and not actually a part of the library's ABI. The fact a symbol is in
comdat is already in the metadata, so it would be useful to add a note about
comdat when showing added/removed functions.
