Tim Armstrong updated IMPALA-7658:
----------------------------------
Description: This function uses GetCodegendComputeFnWrapper() to call the
interpreted path but instead we could codegen the Evaluate() function to reduce
the overhead. I think this is likely to be a little involved since there's a
loop to unroll, so the solution might end up looking like IMPALA-5168 (was:
These utility functions use GetCodegendComputeFnWrapper() to call the
interpreted path but instead we could codegen them into efficient code. We
could either use IRBuilder or, if possible, cross-compile the implementation
and substitute in constants.)
