<H1>History of Berkeley SoftFloat, to Release 3e</H1>
<P>
John R. Hauser<BR>
2018 January 20<BR>
</P>
<H3>Release 3e (2018 January)</H3>
<UL>
<LI>
Changed the default numeric code for optional rounding mode <CODE>odd</CODE>
(round to odd, also known as <EM>jamming</EM>) from 5 to 6.
<LI>
Modified the behavior of rounding mode <CODE>odd</CODE> when rounding to an
integer value (either conversion to an integer format or a
&lsquo;<CODE>roundToInt</CODE>&rsquo; function).
Previously, for those cases only, rounding mode <CODE>odd</CODE> acted the same
as rounding to minimum magnitude.
Now all operations are rounded consistently.
<LI>
Fixed some errors in the specialization code modeling Intel x86 floating-point,
specifically the integers returned on invalid operations and the propagation of
NaN payloads in a few rare cases.
<LI>
Added specialization code modeling ARM floating-point, conforming to VFPv2 or
later.
<LI>
Added an example target for ARM processors.
<LI>
Fixed a minor bug whereby function <CODE>f16_to_ui64</CODE> might return a
different integer than expected in the case that the floating-point operand is
negative.
<LI>
Added example target-specific optimization for GCC, employing GCC instrinsics
and support for <NOBR>128-bit</NOBR> integer arithmetic.
<LI>
Made other minor improvements.
</UL>
<H3>Release 3d (2017 August)</H3>
<UL>
<LI>
Fixed bugs in the square root functions for <NOBR>64-bit</NOBR>
double-precision, <NOBR>80-bit</NOBR> double-extended-precision, and
<NOBR>128-bit</NOBR> quadruple-precision.
For <NOBR>64-bit</NOBR> double-precision (<CODE>f64_sqrt</CODE>), the result
could sometimes be off by <NOBR>1 unit</NOBR> in the last place
(<NOBR>1 ulp</NOBR>) from what it should be.
For the larger formats, the square root could be wrong in a large portion of
the less-significant bits.
(A bug in <CODE>f128_sqrt</CODE> was first reported by Alexei Sibidanov.)
</UL>
<H3>Release 3c (2017 February)</H3>
<UL>
<LI>
Added optional rounding mode <CODE>odd</CODE> (round to odd, also known as
<EM>jamming</EM>).
<LI>
Corrected the documentation concerning non-canonical representations in
<NOBR>80-bit</NOBR> double-extended-precision.
</UL>
<H3>Release 3b (2016 July)</H3>
<UL>
<LI>
Implemented the common <NOBR>16-bit</NOBR> &ldquo;half-precision&rdquo;
floating-point format (<CODE>float16_t</CODE>).
<LI>
Made the integer values returned on invalid conversions to integer formats
be determined by the port-specific specialization instead of being the same for
all ports.
<LI>
Added preprocessor macro <CODE>THREAD_LOCAL</CODE> to allow the floating-point
state (modes and exception flags) to be made per-thread.
<LI>
Modified the provided Makefiles to allow some options to be overridden from the
<CODE>make</CODE> command.
<LI>
Made other minor improvements.
</UL>
<H3>Release 3a (2015 October)</H3>
<UL>
<LI>
Replaced the license text supplied by the University of California, Berkeley.
</UL>
<H3>Release 3 (2015 February)</H3>
<UL>
<LI>
Complete rewrite, funded by the University of California, Berkeley, and
consequently having a different use license than earlier releases.
Major changes included renaming most types and functions, upgrading some
algorithms, restructuring the source files, and making SoftFloat into a true
library.
<LI>
Added functions to convert between floating-point and unsigned integers, both
<NOBR>32-bit</NOBR> and <NOBR>64-bit</NOBR> (<CODE>uint32_t</CODE> and
<CODE>uint64_t</CODE>).
<LI>
Added functions for fused multiply-add, for all supported floating-point
formats except <NOBR>80-bit</NOBR> double-extended-precision.
<LI>
Added support for a fifth rounding mode, <CODE>near_maxMag</CODE> (round to
nearest, with ties to maximum magnitude, away from zero).
<LI>
Dropped the <CODE>timesoftfloat</CODE> program (now part of the Berkeley
TestFloat package).
</UL>
<H3>Release 2c (2015 January)</H3>
<UL>
<LI>
Fixed mistakes affecting some <NOBR>64-bit</NOBR> processors.
<LI>
Further improved the documentation and the wording for the legal restrictions
on using SoftFloat releases <NOBR>through 2c</NOBR> (not applicable to
<NOBR>Release 3</NOBR> or later).
</UL>
<H3>Release 2b (2002 May)</H3>
<UL>
<LI>
Made minor updates to the documentation, including improved wording for the
legal restrictions on using SoftFloat.
</UL>
<H3>Release 2a (1998 December)</H3>
<UL>
<LI>
Added functions to convert between <NOBR>64-bit</NOBR> integers
(<CODE>int64</CODE>) and all supported floating-point formats.
<LI>
Fixed a bug in all <NOBR>64-bit</NOBR>-version square root functions except
<CODE>float32_sqrt</CODE> that caused the result sometimes to be off by
<NOBR>1 unit</NOBR> in the last place (<NOBR>1 ulp</NOBR>) from what it should
be.
(Bug discovered by Paul Donahue.)
<LI>
Improved the Makefiles.
</UL>
<H3>Release 2 (1997 June)</H3>
<UL>
<LI>
Created the <NOBR>64-bit</NOBR> (<CODE>bits64</CODE>) version, adding the
<CODE>floatx80</CODE> and <CODE>float128</CODE> formats.
<LI>
Changed the source directory structure, splitting the sources into a
<CODE>bits32</CODE> and a <CODE>bits64</CODE> version.
Renamed <CODE>environment.h</CODE> to <CODE>milieu.h</CODE> to avoid confusion
with environment variables.
<LI>
Fixed a small error that caused <CODE>float64_round_to_int</CODE> often to
round the wrong way in nearest/even mode when the operand was between
2<SUP>20</SUP> and 2<SUP>21</SUP> and halfway between two integers.
</UL>
<H3>Release 1a (1996 July)</H3>
<UL>
<LI>
Corrected a mistake that caused borderline underflow cases not to raise the
underflow flag when they should have.
(Problem reported by Doug Priest.)
<LI>
Added the <CODE>float_detect_tininess</CODE> variable to control whether
tininess is detected before or after rounding.
</UL>
<H3>Release 1 (1996 July)</H3>
<UL>
<LI>
Original release, based on work done for the International Computer Science
Institute (ICSI) in Berkeley, California.
</UL>

<H2>1. Introduction</H2>
<P>
This document gives information needed for compiling and/or porting Berkeley
SoftFloat, a library of C functions implementing binary floating-point
conforming to the IEEE Standard for Floating-Point Arithmetic.
For basic documentation about SoftFloat refer to
<A HREF="SoftFloat.html"><NOBR><CODE>SoftFloat.html</CODE></NOBR></A>.
</P>
<P>
The source code for SoftFloat is intended to be relatively machine-independent
and should be compilable with any ISO-Standard C compiler that also supports
<NOBR>64-bit</NOBR> integers.
SoftFloat has been successfully compiled with the GNU C Compiler
(<CODE>gcc</CODE>) for several platforms.
</P>
<P>
<NOBR>Release 3</NOBR> of SoftFloat was a complete rewrite relative to
<NOBR>Release 2</NOBR> or earlier.
Changes to the interface of SoftFloat functions are documented in
<A HREF="SoftFloat.html"><NOBR><CODE>SoftFloat.html</CODE></NOBR></A>.
The current version of SoftFloat is <NOBR>Release 3e</NOBR>.
</P>
<H2>2. Limitations</H2>
<P>
SoftFloat assumes the computer has an addressable byte size of either 8 or
<NOBR>16 bits</NOBR>.
(Nearly all computers in use today have <NOBR>8-bit</NOBR> bytes.)
</P>
<P>
SoftFloat is written in C and is designed to work with other C code.
The C compiler used must conform at a minimum to the 1989 ANSI standard for the
C language (same as the 1990 ISO standard) and must in addition support basic
arithmetic on <NOBR>64-bit</NOBR> integers.
Earlier releases of SoftFloat included implementations of <NOBR>32-bit</NOBR>
single-precision and <NOBR>64-bit</NOBR> double-precision floating-point that
did not require <NOBR>64-bit</NOBR> integers, but this option is not supported
starting with <NOBR>Release 3</NOBR>.
Since 1999, ISO standards for C have mandated compiler support for
<NOBR>64-bit</NOBR> integers.
A compiler conforming to the 1999 C Standard or later is recommended but not
strictly required.
</P>
<P>
<NOBR>C Standard</NOBR> header files <CODE>&lt;stdbool.h&gt;</CODE> and
<CODE>&lt;stdint.h&gt;</CODE> are required for defining standard Boolean and
integer types.
If these headers are not supplied with the C compiler, minimal substitutes must
be provided.
SoftFloat&rsquo;s dependence on these headers is detailed later in
<NOBR>section 5.1</NOBR>, <I>Standard Headers <CODE>&lt;stdbool.h&gt;</CODE>
and <CODE>&lt;stdint.h&gt;</CODE></I>.
</P>
<H2>3. Acknowledgments and License</H2>
<P>
The SoftFloat package was written by me, <NOBR>John R.</NOBR> Hauser.
<NOBR>Release 3</NOBR> of SoftFloat was a completely new implementation
supplanting earlier releases.
The project to create <NOBR>Release 3</NOBR> (now <NOBR>through 3e</NOBR>) was
done in the employ of the University of California, Berkeley, within the
Department of Electrical Engineering and Computer Sciences, first for the
Parallel Computing Laboratory (Par Lab) and then for the ASPIRE Lab.
The work was officially overseen by Prof. Krste Asanovic, with funding provided

<H2>4. SoftFloat Package Directory Structure</H2>
<P>
Because SoftFloat is targeted to multiple platforms, its source code is
slightly scattered between target-specific and target-independent directories
and files.
The supplied directory structure is as follows:
<BLOCKQUOTE>
<PRE>
doc
source
include
8086
8086-SSE
ARM-VFPv2
ARM-VFPv2-defaultNaN
build
template-FAST_INT64
template-not-FAST_INT64
Linux-386-GCC
Linux-386-SSE2-GCC
Linux-x86_64-GCC
Linux-ARM-VFPv2-GCC
Win32-MinGW
Win32-SSE2-MinGW
Win64-MinGW-w64
</PRE>
</BLOCKQUOTE>
The majority of the SoftFloat sources are provided in the <CODE>source</CODE>
directory.
The <CODE>include</CODE> subdirectory contains several header files
(unsurprisingly), while the other subdirectories of <CODE>source</CODE> contain
source files that specialize the floating-point behavior to match particular
processor families:
<BLOCKQUOTE>
<DL>
<DT><CODE>8086</CODE></DT>
<DD>
Intel&rsquo;s older, 8087-derived floating-point, extended to all supported
floating-point types
</DD>
<DT><CODE>8086-SSE</CODE></DT>
<DD>
Intel&rsquo;s x86 processors with Streaming SIMD Extensions (SSE) and later
compatible extensions, having 8087 behavior for <NOBR>80-bit</NOBR>
double-extended-precision (<CODE>extFloat80_t</CODE>) and SSE behavior for
other floating-point types
</DD>
<DT><CODE>ARM-VFPv2</CODE></DT>
<DD>
ARM&rsquo;s VFPv2 or later floating-point, with NaN payload propagation
</DD>
<DT><CODE>ARM-VFPv2-defaultNaN</CODE></DT>
<DD>
ARM&rsquo;s VFPv2 or later floating-point, with the &ldquo;default NaN&rdquo;
option
</DD>
</DL>
</BLOCKQUOTE>
If other specializations are attempted, these would be expected to be other
subdirectories of <CODE>source</CODE> alongside the ones listed above.
Specialization is covered later, in <NOBR>section 5.2</NOBR>, <I>Specializing
Floating-Point Behavior</I>.
</P>
<P>
The <CODE>build</CODE> directory is intended to contain a subdirectory for each
target platform for which a build of the SoftFloat library may be created.
For each build target, the target&rsquo;s subdirectory is where all derived
object files and the completed SoftFloat library (typically
<CODE>softfloat.a</CODE> or <CODE>libsoftfloat.a</CODE>) are created.
The two <CODE>template</CODE> subdirectories are not actual build targets but
contain sample files for creating new target directories.
(The meaning of <CODE>FAST_INT64</CODE> will be explained later.)
</P>
<P>
Ignoring the <CODE>template</CODE> directories, the supplied target directories
are intended to follow a naming system of
<NOBR><CODE>&lt;<I>execution-environment</I>&gt;-&lt;<I>compiler</I>&gt;</CODE></NOBR>.
For the example targets,
<NOBR><CODE>&lt;<I>execution-environment</I>&gt;</CODE></NOBR> is
<NOBR><CODE>Linux-386</CODE></NOBR>, <NOBR><CODE>Linux-386-SSE2</CODE></NOBR>,
<NOBR><CODE>Linux-x86_64</CODE></NOBR>,
<NOBR><CODE>Linux-ARM-VFPv2</CODE></NOBR>, <CODE>Win32</CODE>,
<NOBR><CODE>Win32-SSE2</CODE></NOBR>, or <CODE>Win64</CODE>, and
<NOBR><CODE>&lt;<I>compiler</I>&gt;</CODE></NOBR> is <CODE>GCC</CODE>,
<CODE>MinGW</CODE>, or <NOBR><CODE>MinGW-w64</CODE></NOBR>.
</P>
<P>
All of the supplied target directories are merely examples that may or may not
be correct for compiling on any particular system.
Despite requests, there are currently no plans to include and maintain in the
SoftFloat package the build files needed for a great many users&rsquo;
compilation environments, which can span a huge range of operating systems,
compilers, and other tools.
</P>
<P>
As supplied, each target directory contains two files:
<BLOCKQUOTE>
<PRE>
Makefile
platform.h
</PRE>
</BLOCKQUOTE>
The provided <CODE>Makefile</CODE> is written for GNU <CODE>make</CODE>.
A build of SoftFloat for the specific target is begun by executing the
<CODE>make</CODE> command with the target directory as the current directory.
A completely different build tool can be used if an appropriate
<CODE>Makefile</CODE> equivalent is created.
</P>
<P>
The <CODE>platform.h</CODE> header file exists to provide a location for
additional C declarations specific to the build target.
Every C source file of SoftFloat contains a <CODE>#include</CODE> for
<CODE>platform.h</CODE>.
In many cases, the contents of <CODE>platform.h</CODE> can be as simple as one
or two lines of code.
At the other extreme, to get maximal performance from SoftFloat, it may be
desirable to include in header <CODE>platform.h</CODE> (directly or via
<CODE>#include</CODE>) declarations for numerous target-specific optimizations.
Such possibilities are discussed in the next section, <I>Issues for Porting
SoftFloat to a New Target</I>.
If the target&rsquo;s compiler or library has bugs or other shortcomings,
workarounds for these issues may also be possible with target-specific
declarations in <CODE>platform.h</CODE>, avoiding the need to modify the main
SoftFloat sources.
</P>
<H2>5. Issues for Porting SoftFloat to a New Target</H2>
<H3>5.1. Standard Headers <CODE>&lt;stdbool.h&gt;</CODE> and <CODE>&lt;stdint.h&gt;</CODE></H3>
<P>
The SoftFloat sources make use of standard headers
<CODE>&lt;stdbool.h&gt;</CODE> and <CODE>&lt;stdint.h&gt;</CODE>, which have
been part of the ISO C Standard Library since 1999.
With any recent compiler, these standard headers are likely to be supported,
even if the compiler does not claim complete conformance to the latest ISO C
Standard.
For older or nonstandard compilers, substitutes for
<CODE>&lt;stdbool.h&gt;</CODE> and <CODE>&lt;stdint.h&gt;</CODE> may need to be
created.
SoftFloat depends on these names from <CODE>&lt;stdbool.h&gt;</CODE>:
<BLOCKQUOTE>
<PRE>
bool
true
false
</PRE>
</BLOCKQUOTE>
and on these names from <CODE>&lt;stdint.h&gt;</CODE>:
<BLOCKQUOTE>
<PRE>
uint16_t
uint32_t
uint64_t
int32_t
int64_t
UINT64_C

uint_fast64_t
int_fast8_t

int_fast32_t
int_fast64_t
</PRE>
</BLOCKQUOTE>
</P>
<H3>5.2. Specializing Floating-Point Behavior</H3>
<P>
The IEEE Floating-Point Standard allows for some flexibility in a conforming
implementation, particularly concerning NaNs.
The SoftFloat <CODE>source</CODE> directory is supplied with some
<I>specialization</I> subdirectories containing possible definitions for this
implementation-specific behavior.
For example, the <CODE>8086</CODE> and <NOBR><CODE>8086-SSE</CODE></NOBR>
subdirectories have source files that specialize SoftFloat&rsquo;s behavior to
match that of Intel&rsquo;s x86 line of processors.
The files in a specialization subdirectory must determine:
<UL>
<LI>
whether tininess for underflow is detected before or after rounding by default;
<LI>
how signaling NaNs are distinguished from quiet NaNs;
<LI>
what (if anything) special happens when exceptions are raised;
<LI>
the default generated quiet NaNs;
<LI>
how NaNs are propagated from function inputs to output; and
<LI>
the integer results returned when conversions to integer type raise the
<I>invalid</I> exception.
</UL>
</P>
<P>
As provided, the build process for a target expects to involve exactly
<EM>one</EM> specialization directory that defines <EM>all</EM> of these
implementation-specific details for the target.
A specialization directory such as <CODE>8086</CODE> is expected to contain a
header file called <CODE>specialize.h</CODE>, together with whatever other
source files are needed to complete the specialization.
</P>
<P>
A new build target may use an existing specialization, such as the ones
provided by the <CODE>8086</CODE> and <NOBR><CODE>8086-SSE</CODE></NOBR>
subdirectories.
If a build target needs a new specialization, different from any existing ones,
it is recommended that a new specialization directory be created for this
purpose.
The <CODE>specialize.h</CODE> header file from any of the provided
specialization subdirectories can be used as a model for what definitions are
needed.
</P>
<H3>5.3. Macros for Build Options</H3>
<P>
The SoftFloat source files adapt the floating-point implementation according to
several C preprocessor macros:
<BLOCKQUOTE>
<DL>
<DT><CODE>LITTLEENDIAN</CODE>
<DD>
Must be defined for little-endian machines; must not be defined for big-endian
machines.
<DT><CODE>INLINE</CODE>
<DD>
Specifies the sequence of tokens used to indicate that a C function should be
inlined.
If macro <CODE>INLINE_LEVEL</CODE> is defined with a value of 1 or higher, this
macro must be defined; otherwise, this macro is ignored and need not be
defined.
For compilers that conform to the C Standard&rsquo;s rules for inline
functions, this macro can be defined as the single keyword <CODE>inline</CODE>.
For other compilers that follow a convention pre-dating the standardization of
<CODE>inline</CODE>, this macro may need to be defined to <CODE>extern</CODE>
<CODE>inline</CODE>.
<DT><CODE>THREAD_LOCAL</CODE>
<DD>
Can be defined to a sequence of tokens that, when appearing at the start of a
variable declaration, indicates to the C compiler that the variable is
<I>per-thread</I>, meaning that each execution thread gets its own separate
instance of the variable.
This macro is used in header <CODE>softfloat.h</CODE> in the declarations of
variables <CODE>softfloat_roundingMode</CODE>,
<CODE>softfloat_detectTininess</CODE>, <CODE>extF80_roundingPrecision</CODE>,
and <CODE>softfloat_exceptionFlags</CODE>.
If macro <CODE>THREAD_LOCAL</CODE> is left undefined, these variables will
default to being ordinary global variables.
Depending on the compiler, possible valid definitions of this macro include
<CODE>_Thread_local</CODE> and <CODE>__thread</CODE>.
</DL>
<DL>
<DT><CODE>SOFTFLOAT_ROUND_ODD</CODE>
<DD>
Can be defined to enable support for optional rounding mode
<CODE>softfloat_round_odd</CODE>.
</DL>
<DL>
<DT><CODE>INLINE_LEVEL</CODE>
<DD>
Can be defined to an integer to determine the degree of inlining requested of
the compiler.
Larger numbers request that more inlining be done.
If this macro is not defined or is defined to a value less <NOBR>than 1</NOBR>
(zero or negative), no inlining is requested.
The maximum effective value is no higher <NOBR>than 5</NOBR>.
Defining this macro to a value greater than 5 is the same as defining it
<NOBR>to 5</NOBR>.
<DT><CODE>SOFTFLOAT_FAST_INT64</CODE>
<DD>
Can be defined to indicate that the build target&rsquo;s implementation of
<NOBR>64-bit</NOBR> arithmetic is efficient.
For newer <NOBR>64-bit</NOBR> processors, this macro should usually be defined.
For very small microprocessors whose buses and registers are <NOBR>8-bit</NOBR>
or <NOBR>16-bit</NOBR> in size, this macro should usually not be defined.
Whether this macro should be defined for a <NOBR>32-bit</NOBR> processor may
depend on the target machine and the applications that will use SoftFloat.
<DT><CODE>SOFTFLOAT_FAST_DIV32TO16</CODE>
<DD>
Can be defined to indicate that the target&rsquo;s division operator
<NOBR>in C</NOBR> (written as <CODE>/</CODE>) is reasonably efficient for
dividing a <NOBR>32-bit</NOBR> unsigned integer by a <NOBR>16-bit</NOBR>
unsigned integer.
Setting this macro may affect the performance of function <CODE>f16_div</CODE>.
<DT><CODE>SOFTFLOAT_FAST_DIV64TO32</CODE>
<DD>
Can be defined to indicate that the target&rsquo;s division operator
<NOBR>in C</NOBR> (written as <CODE>/</CODE>) is reasonably efficient for
dividing a <NOBR>64-bit</NOBR> unsigned integer by a <NOBR>32-bit</NOBR>
unsigned integer.
Setting this macro may affect the performance of division, remainder, and
square root operations other than <CODE>f16_div</CODE>.
</DL>
</BLOCKQUOTE>
</P>
<P>
Following the usual custom <NOBR>for C</NOBR>, for most of these macros (all
except <CODE>INLINE</CODE>, <CODE>THREAD_LOCAL</CODE>, and
<CODE>INLINE_LEVEL</CODE>), the content of any definition is irrelevant;
what matters is a macro&rsquo;s effect on <CODE>#ifdef</CODE> directives.
</P>
<P>
It is recommended that any definitions of macros <CODE>LITTLEENDIAN</CODE>,
<CODE>INLINE</CODE>, and <CODE>THREAD_LOCAL</CODE> be made in a build
target&rsquo;s <CODE>platform.h</CODE> header file, because these macros are
expected to be determined inflexibly by the target machine and compiler.
The other five macros select options and control optimization, and thus might
be better located in the target&rsquo;s Makefile (or its equivalent).
</P>
<H3>5.4. Adapting a Template Target Directory</H3>
<P>
In the <CODE>build</CODE> directory, two <CODE>template</CODE> subdirectories
provide models for new target directories.
Two different templates exist because different functions are needed in the
SoftFloat library depending on whether macro <CODE>SOFTFLOAT_FAST_INT64</CODE>
is defined.
If macro <CODE>SOFTFLOAT_FAST_INT64</CODE> will be defined,
<NOBR><CODE>template-FAST_INT64</CODE></NOBR> is the template to use;
otherwise, <NOBR><CODE>template-not-FAST_INT64</CODE></NOBR> is the appropriate
template.
A new target directory can be created by copying the correct template directory
and editing the files inside.
To avoid confusion, it would be wise to refrain from editing the files within a
template directory directly.
</P>
<H3>5.5. Target-Specific Optimization of Primitive Functions</H3>
<P>
Header file <CODE>primitives.h</CODE> (in directory
<CODE>source/include</CODE>) declares macros and functions for numerous
underlying arithmetic operations upon which many of SoftFloat&rsquo;s
floating-point functions are ultimately built.
The SoftFloat sources include implementations of all of these functions/macros,
written as standard C code, so a complete and correct SoftFloat library can be
created using only the supplied code for all functions.
However, for many targets, SoftFloat&rsquo;s performance can be improved by
substituting target-specific implementations of some of the functions/macros
declared in <CODE>primitives.h</CODE>.
</P>
<P>
For example, <CODE>primitives.h</CODE> declares a function called
<CODE>softfloat_countLeadingZeros32</CODE> that takes an unsigned
<NOBR>32-bit</NOBR> integer as an argument and returns the number of the
integer&rsquo;s most-significant bits that are zeros.
While the SoftFloat sources include an implementation of this function written
in <NOBR>standard C</NOBR>, many processors can perform this same function
directly in only one or two machine instructions.
An alternative, target-specific implementation that maps to those instructions
is likely to be more efficient than the generic C code from the SoftFloat
package.
</P>
<P>
A build target can replace the supplied version of any function or macro of
<CODE>primitives.h</CODE> by defining a macro with the same name in the
target&rsquo;s <CODE>platform.h</CODE> header file.
For this purpose, it may be helpful for <CODE>platform.h</CODE> to
<CODE>#include</CODE> header file <CODE>primitiveTypes.h</CODE>, which defines
types used for arguments and results of functions declared in
<CODE>primitives.h</CODE>.
When a desired replacement implementation is a function, not a macro, it is
sufficient for <CODE>platform.h</CODE> to include the line
<BLOCKQUOTE>
<PRE>
#define &lt;<I>function-name</I>&gt; &lt;<I>function-name</I>&gt;
</PRE>
</BLOCKQUOTE>
where <NOBR><CODE>&lt;<I>function-name</I>&gt;</CODE></NOBR> is the name of the
function.
This technically defines <NOBR><CODE>&lt;<I>function-name</I>&gt;</CODE></NOBR>
as a macro, but one that resolves to the same name, which may then be a
function.
(A preprocessor that conforms to the C Standard is required to limit recursive
macro expansion from being applied more than once.)
</P>
<P>
The supplied header file <CODE>opts-GCC.h</CODE> (in directory
<CODE>source/include</CODE>) provides an example of target-specific
optimization for the GCC compiler.
Each GCC target example in the <CODE>build</CODE> directory has
<BLOCKQUOTE>
<CODE>#include "opts-GCC.h"</CODE>
</BLOCKQUOTE>
in its <CODE>platform.h</CODE> header file.
Before <CODE>opts-GCC.h</CODE> is included, the following macros must be
defined (or not) to control which features are invoked:
<BLOCKQUOTE>
<DL>
<DT><CODE>SOFTFLOAT_BUILTIN_CLZ</CODE></DT>
<DD>
If defined, SoftFloat&rsquo;s internal
&lsquo;<CODE>countLeadingZeros</CODE>&rsquo; functions use intrinsics
<CODE>__builtin_clz</CODE> and <CODE>__builtin_clzll</CODE>.
</DD>
<DT><CODE>SOFTFLOAT_INTRINSIC_INT128</CODE></DT>
<DD>
If defined, SoftFloat makes use of GCC&rsquo;s nonstandard <NOBR>128-bit</NOBR>
integer type <CODE>__int128</CODE>.
</DD>
</DL>
</BLOCKQUOTE>
On some machines, these improvements are observed to increase the speeds of
<CODE>f64_mul</CODE> and <CODE>f128_mul</CODE> by around 20 to 25%, although
other functions receive less dramatic boosts, or none at all.
Results can vary greatly across different platforms.
</P>
<H2>6. Testing SoftFloat</H2>
<P>
SoftFloat can be tested using the <CODE>testsoftfloat</CODE> program by the
same author.
This program is part of the Berkeley TestFloat package available at the Web
page
<A HREF="http://www.jhauser.us/arithmetic/TestFloat.html"><NOBR><CODE>http://www.jhauser.us/arithmetic/TestFloat.html</CODE></NOBR></A>.
The TestFloat package also has a program called <CODE>timesoftfloat</CODE> that
measures the speed of SoftFloat&rsquo;s floating-point functions.
</P>
<H2>7. Providing SoftFloat as a Common Library for Applications</H2>
<P>
Header file <CODE>softfloat.h</CODE> defines the SoftFloat interface as seen by
clients.
If the SoftFloat library will be made a common library for programs on a
system, the supplied <CODE>softfloat.h</CODE> has a couple of deficiencies for
this purpose:
<UL>
<LI>
As supplied, <CODE>softfloat.h</CODE> depends on another header,
<CODE>softfloat_types.h</CODE>, that is not intended for public use but which
must also be visible to the programmer&rsquo;s compiler.
<LI>
More troubling, at the time <CODE>softfloat.h</CODE> is included in a C source
file, macros <CODE>SOFTFLOAT_FAST_INT64</CODE> and <CODE>THREAD_LOCAL</CODE>
must be defined, or not defined, consistent with how these macro were defined
when the SoftFloat library was built.
</UL>
In the situation that new programs may regularly <CODE>#include</CODE> header
file <CODE>softfloat.h</CODE>, it is recommended that a custom, self-contained
version of this header file be created that eliminates these issues.
</P>
<H2>8. Contact Information</H2>
<P>
At the time of this writing, the most up-to-date information about SoftFloat
and the latest release can be found at the Web page
<A HREF="http://www.jhauser.us/arithmetic/SoftFloat.html"><NOBR><CODE>http://www.jhauser.us/arithmetic/SoftFloat.html</CODE></NOBR></A>.
