-# Information about tests are stored in: %results
-# $results{$test}{"type"} is the result type, e.g. normal or complex.
-# In the following description $platform, $type and $float are:
-# - $platform is the used platform
-# - $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}{$platform}{$type}{$float} is defined and has a delta
-# or 'fail' as value.
