           Summary: Invalid transformation for vaargs functions.
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: llvm-gcc
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: asl at math.spbu.ru


Consider the attached C source (from gcc testsuite).

The call to function f is converted to LLVM IR incorrectly: i8/16 args will be
extended to 32 bits, but args handling logic in f() itself assumes, that they
are all in place.
