; Check that the unexpanded accumulator functions and the dummy variables are deleted.
; There doesn't seem to be any way to compute the basename of %s, hence the unfortunate
;   explicit uses of "test_reduce_general_cleanup" below.
; There doesn't seem to be a way to write a CHECK-NOT pattern that matches only at the
;   end of a line (llvm-objdump dumps symbol name at end of line), so sed is employed
;   to add a '<' at the end of each line (symbol name).  This allows us to use (e.g.)
;   "aiAccum<" to match the symbol "aiAccum" but not the symbol "aiAccum.expand".
