           Summary: constant pools out of range
           Product: libraries
           Version: trunk
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Backend: ARM
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: bob.wilson at apple.com

A number of the MultiSource tests are failing on ARM because the constant pools
are too far away from the loads that reference them.  Most of the offsets are
only slightly too large.  For example:

/Volumes/LocalHD/bwilson/nightly/test/llvm/Release/bin/llc -O3
-relocation-model=pic -mcpu=arm1136jf-s -f Output/treecc.llvm.bc -o
gcc Output/treecc.llc.s -o Output/treecc.llc  -lm  -arch armv6 -isysroot
Output/treecc.llc.s:9173:bad immediate value for offset (4112)
Output/treecc.llc.s:9084:bad immediate value for offset (4104)
Output/treecc.llc.s:9056:bad immediate value for offset (4108)
Output/treecc.llc.s:9037:bad immediate value for offset (4108)
Output/treecc.llc.s:8971:bad immediate value for offset (4104)
Output/treecc.llc.s:8948:bad immediate value for offset (4104)
Output/treecc.llc.s:8898:bad immediate value for offset (4100)
Output/treecc.llc.s:8647:bad immediate value for offset (4104)
make[3]: [Output/treecc.llc] Error 1 (ignored)
