History of Major Changes to TestFloat, up to Release 2a

The TestFloat releases parallel those of SoftFloat, on which TestFloat is
|
||
|
|
based. Each TestFloat release also incorporates all bug fixes from the
|
||
|
|
corresponding release of SoftFloat.

Release 2a (1998 December)
|
||
|
|
|
||
|
|
-- Added support for testing conversions between floating-point and 64-bit
|
||
|
|
integers.
|
||
|
|
|
||
|
|
-- Improved the makefiles.

Release 2 (1997 June)
|
||
|
|
|
||
|
|
-- Integrated the generation of test cases and the checking of system
|
||
|
|
results into a single program. (Before they were separate programs,
|
||
|
|
normally joined by explicit command-line pipes.)
|
||
|
|
|
||
|
|
-- Improved the sequence of test cases.
|
||
|
|
|
||
|
|
-- Added support for testing extended double precision and quadruple
|
||
|
|
precision.
|
||
|
|
|
||
|
|
-- Made program output more readable, and added new command arguments.
|
||
|
|
|
||
|
|
-- Reduced dependence on the quality of the standard `random' function for
|
||
|
|
generating test cases. (Previously naively expected `random' to be able
|
||
|
|
to generate good random bits for the entire machine word width.)
|
||
|
|
|
||
|
|
-- Created `testsoftfloat', with its own simpler complete software floating-
|
||
|
|
point (``slowfloat'') for comparison purposes.
|
||
|
|
|
||
|
|
-- Made some changes to the source file structure, including renaming
|
||
|
|
`environment.h' to `milieu.h' (to avoid confusion with environment
|
||
|
|
variables).

Release 1a (1996 July)
|
||
|
|
|
||
|
|
-- Added the `-tininessbefore' and `-tininessafter' options to control
|
||
|
|
whether tininess should be detected before or after rounding.
