            Bug ID: 87071
           Summary: LLVM triggered Diagnostic Handler: unsupported call to
                    function S2KItSaltedSHA1Generator in gpg
           Product: Mesa
           Version: 10.3
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: devurandom@gmx.net

Mesa 10.3.4 / LLVM 3.5.0 / libclc 0.0.1_pre20141027 seems to be unable to
compile the OpenCL function S2KItSaltedSHA1Generator from current
John-The-Ripper Git [1].

The function is too long to quote here, but the signature is:
inline void S2KItSaltedSHA1Generator(__global const uchar *password, int
password_length, __global const uchar *salt, int count, __global uchar *key,
int length)

My hardware as reported by JTR is:
