Subject: [PATCH] biarch compiler support for i386
Date: Mon, 04 Apr 2005 23:14:16 -0700 [thread overview]
Message-ID: <42522CB8.1010007@zytor.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 267 bytes --]
This allows the i386 architecture to be built on a system with a biarch
compiler that defaults to x86-64, merely by specifying ARCH=i386.
As previously discussed, this uses the equivalent logic to the ppc port.
