Details:

Good evening to everyone.

We are facing problems for building octave 4.1+ with jit.
The version of LLVM in use is 3.3.
The file that is been modifyed is jit-typeinfo.cc.

The compiler fails because is not confident to decide between two alternative
functions; one setting the arg as double and the other setting the arg as
octave_idx_type.

This function is responsible of returning the result for an invalid index.

If the parameter -1 that sets this behaviour is cast to double, the
compilation succeds.


---------------

extern "C" void
octave_jit_ginvalid_index (void)
{
  // FIXME: 0-argument form of err_invalid_index removed in cset dd6345fd8a97
  //        Report -1 as the bad index for all occurrences.
  err_invalid_index ((double)-1);
}
-----------------
