From 3b7ce726258de20be2d65f7b9f51b160dd99638a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Fonseca?= Date: Tue, 4 Dec 2012 16:54:41 +0000 Subject: [PATCH] gallivm: Allow indirection from TEMP registers too. The ADDR file is cumbersome for native integer capable drivers. We should consider deprecating it eventually, but this just adds support for indirection from TEMP registers.
