New Revision: 46434
URL: https://svnweb.freebsd.org/changeset/doc/46434
Log:
custom-gcc: modernize
- use pkg instead of directly installing from ports
- reduce references to old versions of gcc, and make the article more
future-proof
- now that we either have a modern version of gcc or clang in base / as
the package building compiler, the impact of binary perf is no longer
relevant.
really, this article should either move into the handbook or be removed.
