Bug ID: 28058
Summary: 300x performance regression in strip
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: mail at nh2 dot me
Target Milestone: ---
Dear maintainer,
I found a performance regression between binutils 2.34 and 2.35.1 that makes
stripping a 50 MB `.a` take 300 seconds instead of 1 second.
Original investigation, including `.a` file for testing:
https://github.com/NixOS/nixpkgs/issues/129467
I bisected the issue to this commit:
a8e14f4cc2badfcf959f5e2cc57a941dc43f72d4 is the first bad commit
commit a8e14f4cc2badfcf959f5e2cc57a941dc43f72d4

Add support for ELF files which contain multiple reloc sections which
all target the same section.
Note that this is the same commit that introduced the performance regression in
`as` in this bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=26406
However, the commit that fixed `as` in there does not fix this regression.
I would appreciate if you could have a look!
Niklas
