Subject: [patch 04/14] ia64: Remove the __SMALL_ADDR_AREA attribute for per cpu access
Date: Mon, 26 Nov 2007 16:14:11 -0800 [thread overview]
Message-ID: <20071127001430.083503280@sgi.com> (raw)
In-Reply-To: 20071127001407.859743255@sgi.com
[-- Attachment #1: remove_ia64_model_section --]
[-- Type: text/plain, Size: 2586 bytes --]
The model(small) attribute is not supported by gcc 4.X. The tests
will always be negative today.
