Module Name: src
Committed By: christos
Date: Thu Apr 12 20:48:42 UTC 2018
Modified Files:
src/sys/sys: exec_elf.h
Log Message:
There have never been binaries with a checksum tag for NetBSD.
These days the equivalent functionality is provided by the build
id tag. It was incorrect in the first place to overload tag #2
(which used to be the emulation name) with a different meaning, so
actually document the meaning that was once used (because binaries
with that tag exist).
Tag existance noticed by kre@
