+# Information about tests are stored in: %results
+# $results{$test}{"kind"} is either "fct" or "test" and flags whether this

+# $results{$test}{"type"} is the result type, e.g. normal or complex.
+# $results{$test}{"has_ulps"} is set if deltas exist.
+# $results{$test}{"has_fails"} is set if exptected failures exist.
+# In the following description $type and $float are:
+# - $type is either "normal", "real" (for the real part of a complex number)
+#   or "imag" (for the imaginary part # of a complex number).
+# - $float is either of float, ifloat, double, idouble, ldouble, ildouble;
+#   It represents the underlying floating point type (float, double or long
+#   double) and if inline functions (the leading i stands for inline)
+#   are used.
+# $results{$test}{$type}{"fail"}{$float} is defined and has a 1 if
+# the test is expected to fail
+# $results{$test}{$type}{"ulp"}{$float} is defined and has a delta as value
