Subject: Use the generic Sparc CPU handling for Linux, FreeBSD and OpenBSD, too.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=cf22e53990915d032047eb0dbd2b7f1bdf966a91;p=clang

Use the generic Sparc CPU handling for Linux, FreeBSD and OpenBSD, too.
This currently changes the default toward the more historic -Av8/-Av9,
but as discussed with James Y Knight, consistency is for now more
important than figuring out which default CPU each OS should be using.
