* MFC r326276:Eitan Adler2018-03-051-1/+3
| | | | | | | | | | | | | | | | | | | various: general adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

* Tweak the support for using ldd on 32-bit objects a bit further.John Baldwin2008-08-011-31/+66
| | | | | | | | | | | | | | | | Specifically, build a 32-bit /usr/bin/ldd32 on amd64 which handles 32-bit objects. Since it is a 32-bit binary, it can fork a child process which can dlopen() a 32-bit shared library. The current 32-bit support in ldd can't do this because it does the dlopen() from a 64-bit process. In order to preserve an intuitive interface for users, the ldd binary automatically execs /usr/bin/ldd32 for 32-bit objects. The end result is that ldd on amd64 now transparently handles 32-bit shared libraries in addition to 32-bit binaries. Submitted by: ps (indirectly) Notes: svn path=/head/; revision=181136
