           Summary: llvm-ld should optimize for the target it is compiling
                    for
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: llvm-ld
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: stein at ir.iit.edu

Currently, if BitCode does not have a target set in it,
llvm-ld -native
will use the default target, and optimize for that,
then compile for its target, which may be different.
Instead, it would make much more sense if it only
used the target it was compiling for, even if that
is different from that specified in the BitCode.

Though, if the BitCode target and llvm-ld target
explicitly disagree, that should probably have a warning.
