21# This file needs to be tidied up
22# Note that functions and tests share the same namespace.
23
24# Information about tests are stored in: %results
25# $results{$test}{"kind"} is either "fct" or "test" and flags whether this
26# is a maximal error of a function or a single test.
27# $results{$test}{"type"} is the result type, e.g. normal or complex.
28# $results{$test}{"has_ulps"} is set if deltas exist.
29# $results{$test}{"has_fails"} is set if exptected failures exist.
30# In the following description $type and $float are:
31# - $type is either "normal", "real" (for the real part of a complex number)
32# or "imag" (for the imaginary part # of a complex number).
33# - $float is either of float, ifloat, double, idouble, ldouble, ildouble;
34# It represents the underlying floating point type (float, double or long
35# double) and if inline functions (the leading i stands for inline)
36# are used.
37# $results{$test}{$type}{"fail"}{$float} is defined and has a 1 if
38# the test is expected to fail
39# $results{$test}{$type}{"ulp"}{$float} is defined and has a delta as value
