# This file needs to be tidied up
# Note that functions and tests share the same namespace.

# Information about tests are stored in: %results
# $results{$test}{"kind"} is either "fct" or "test" and flags whether this
# is a maximal error of a function or a single test.
# $results{$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
