Subject: [PATCH][RFC] gcc3 arch options
Date: Mon, 27 May 2002 17:00:48 +0200 [thread overview]
Message-ID: <20020527150048.GC6738@werewolf.able.es> (raw)
Hi.
Patch below adds support for newer gcc -march code generation options.
It adds options for pentium-mmx, pentium-pro, pentium2, pentium3 and pentium4.
(note: pII part depends or previous patch).
It just what Luca Barbieri did adding PII.
I have been running a PII optmized kernel on a dual PII@400 box and nothing
has broken for 2 days....
Patch follows:
