-Documentation for the `timesoftfloat' Program of SoftFloat Release 2a

-John R. Hauser

-
--------------------------------------------------------------------------------
-Introduction
-
-The `timesoftfloat' program evaluates the speed of SoftFloat's floating-
-point routines. Each routine can be evaluated for every relevant rounding
-mode, tininess mode, and/or rounding precision.

-Legal Notice
-
-The `timesoftfloat' program was written by John R. Hauser.
-
-THIS SOFTWARE IS DISTRIBUTED AS IS, FOR FREE. Although reasonable effort
-has been made to avoid it, THIS SOFTWARE MAY CONTAIN FAULTS THAT WILL AT
-TIMES RESULT IN INCORRECT BEHAVIOR. USE OF THIS SOFTWARE IS RESTRICTED TO
-PERSONS AND ORGANIZATIONS WHO CAN AND WILL TAKE FULL RESPONSIBILITY FOR ANY
-AND ALL LOSSES, COSTS, OR OTHER PROBLEMS ARISING FROM ITS USE.
-
-
--------------------------------------------------------------------------------
-Executing `timesoftfloat'
-
-The `timesoftfloat' program is intended to be invoked from a command line
-interpreter as follows:
-
- timesoftfloat [<option>...] <function>
-
-Here square brackets ([]) indicate optional items, while angled brackets
-(<>) denote parameters to be filled in. The `<function>' argument is
-the name of the SoftFloat routine to evaluate, such as `float32_add' or
-`float64_to_int32'. The allowed options are detailed in the next section,
-_Options_. If `timesoftfloat' is executed without any arguments, a summary
-of usage is written. It is also possible to evaluate all machine functions
-in a single invocation as explained in the section _Function_Sets_ later in
-this document.
-
-Ordinarily, a function's speed will be evaulated separately for each of
-the four rounding modes, one after the other. If the rounding mode is not
-supposed to have any affect on the results of a function--for instance,
-some operations do not require rounding--only the nearest/even rounding mode
-is timed. In the same way, if a function is affected by the way in which
-underflow tininess is detected, `timesoftfloat' times the function both with
-tininess detected before rounding and after rounding. For extended double-
-precision operations affected by rounding precision control, `timesoftfloat'
-also times the function for all three rounding precision modes, one after
-the other. Evaluation of a function can be limited to a single rounding
-mode, a single tininess mode, and/or a single rounding precision with
-appropriate options (see _Options_).
-
-For each function and mode evaluated, `timesoftfloat' reports the speed of
-the function in kops/s, or ``thousands of operations per second''. This
-unit of measure differs from the traditional MFLOPS (``millions of floating-
-point operations per second'') only in being a factor of 1000 smaller.
-(1000 kops/s is exactly 1 MFLOPS.) Speeds are reported in thousands instead
-of millions because software floating-point often executes at less than
-1 MFLOPS.
-
-The speeds reported by `timesoftfloat' may be affected somewhat by other
-programs executing at the same time as `timesoftfloat'.
-
-Note that the remainder operations (`float32_rem', `float64_rem',
-`floatx80_rem' and `float128_rem') will be markedly slower than other
-operations, particularly for extended double precision (`floatx80') and
-quadruple precision (`float128'). This is inherent to the remainder
-function itself and is not a failing of the SoftFloat implementation.
-
-
--------------------------------------------------------------------------------
-Options
-
-The `timesoftfloat' program accepts several command options. If mutually
-contradictory options are given, the last one has priority.
-
-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
--help
-
-The `-help' option causes a summary of program usage to be written, after
-which the program exits.

--precision32, -precision64, -precision80
-
-For extended double-precision functions affected by rounding precision
-control, the `-precision32' option restricts evaluation to only the cases
-in which rounding precision is equivalent to single precision. The other
-rounding precision options are not timed. Likewise, the `-precision64'
-and `-precision80' options fix the rounding precision equivalent to double
-precision or extended double precision, respectively. These options are
-ignored for functions not affected by rounding precision control.
-

--nearesteven, -tozero, -down, -up
-
-The `-nearesteven' option restricts evaluation to only the cases in which
-the rounding mode is nearest/even. The other rounding mode options are not
-timed. Likewise, `-tozero' forces rounding to zero; `-down' forces rounding
-down; and `-up' forces rounding up. These options are ignored for functions
-that are exact and thus do not round.
-
-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
--tininessbefore, -tininessafter
-
-The `-tininessbefore' option restricts evaluation to only the cases
-detecting underflow tininess before rounding. Tininess after rounding
-is not timed. Likewise, `-tininessafter' forces underflow tininess to be
-detected after rounding only. These options are ignored for functions not
-affected by the way in which underflow tininess is detected.

--------------------------------------------------------------------------------
-Function Sets
-
-Just as `timesoftfloat' can test an operation for all four rounding modes in
-sequence, multiple operations can also be tested with a single invocation.
-Three sets are recognized: `-all1', `-all2', and `-all'. The set `-all1'
-comprises all one-operand functions; `-all2' is all two-operand functions;
-and `-all' is all functions. A function set can be used in place of a
-function name in the command line, as in
-
- timesoftfloat [<option>...] -all
