           Summary: llc should warn about invalid target triple
           Product: tools
           Version: 2.8
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: llc
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: llvm at henning-thielemann.de
                CC: llvmbugs at cs.uiuc.edu


When I write an invalid target triple into an LL file,
then llc generates a CPP file without any warning.
It should at least give a warning, but better fail.
The message could also tell how to find out available target-triples.

$ cat invalidtarget.ll
target triple = "invalid"

define i8 @func(i8) {
_L1:
  ret i8 %0
}

$ llc invalidtarget.ll
$ ls -1 invalidtarget.*
invalidtarget.cpp
invalidtarget.ll
