           Summary: relocation type 10 (R_ALPHA_SREL32) not handled by
                    elfloader.c
           Product: xorg
           Version: 6.7.0
          Platform: DEC
               URL: http://www.freebsd.org/cgi/query-pr.cgi?pr=73257
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Server/general
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: kstailey at yahoo.com


Platform:  DEC AlphaServer 1000A with Matrox Mystique card. 

OS: FreeBSD 5.3-BETA7

When I start the Xorg server I see numerous error messages about relocation type
10 not being handled.  This patch adds the missing support to 6.7.0.  I checked
6.8.1 and HEAD and did not see this code applied.
