Berkeley SoftFloat is a software implementation of binary floating-point that
|
||||
conforms to the IEEE Standard for Floating-Point Arithmetic.
|
||||
SoftFloat is distributed in the form of C source code.
|
||||
Building the SoftFloat sources generates a library file (typically
|
||||
<CODE>softfloat.a</CODE> or <CODE>libsoftfloat.a</CODE>) containing the
|
||||
floating-point subroutines.

|
||||
|
||||
Berkeley SoftFloat is a software implementation of binary floating-point
|
||||
that conforms to the IEEE Standard for Floating-Point Arithmetic. SoftFloat
|
||||
is distributed in the form of C source code. Building the SoftFloat sources
|
||||
generates a library file (typically "softfloat.a" or "libsoftfloat.a")
|
||||
containing the floating-point subroutines.
|
||||
|
||||
The SoftFloat package is documented in the following files in the "doc"
|
||||
subdirectory:
|
||||
|
||||
SoftFloat.html Documentation for using the SoftFloat functions.
|
||||
SoftFloat-source.html Documentation for building SoftFloat.
|
||||
SoftFloat-history.html History of the major changes to SoftFloat.
|
||||
|
||||
Other files in the package comprise the source code for SoftFloat.

<H1>History of Berkeley SoftFloat, to Release 3e</H1>

|
||||
<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
|
||||
‘<CODE>roundToInt</CODE>’ 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> “half-precision”
|
||||
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>

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><stdbool.h></CODE> and
|
||||
<CODE><stdint.h></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’s dependence on these headers is detailed later in
|
||||
<NOBR>section 5.1</NOBR>, <I>Standard Headers <CODE><stdbool.h></CODE>
|
||||
and <CODE><stdint.h></CODE></I>.

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>
|

Because SoftFloat is targeted to multiple platforms, its source code is

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’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><<I>execution-environment</I>>-<<I>compiler</I>></CODE></NOBR>.
|
||||
For the example targets,
|
||||
<NOBR><CODE><<I>execution-environment</I>></CODE></NOBR> is
|

<NOBR><CODE>Linux-386</CODE></NOBR>, <NOBR><CODE>Linux-386-SSE2</CODE></NOBR>,

<NOBR><CODE><<I>compiler</I>></CODE></NOBR> is <CODE>GCC</CODE>,

</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’
|
||||
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’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.

<H3>5.1. Standard Headers <CODE><stdbool.h></CODE> and <CODE><stdint.h></CODE></H3>
|
||||
|

<P>
|
||||
The SoftFloat sources make use of standard headers
|
||||
<CODE><stdbool.h></CODE> and <CODE><stdint.h></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><stdbool.h></CODE> and <CODE><stdint.h></CODE> may need to be
|
||||
created.
|
||||
SoftFloat depends on these names from <CODE><stdbool.h></CODE>:

<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’s behavior to
|
||||
match that of Intel’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.

<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’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’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.

<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’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’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’s Makefile (or its equivalent).

<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’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’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’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’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 <<I>function-name</I>> <<I>function-name</I>>
|
||||
</PRE>
|
||||
</BLOCKQUOTE>
|
||||
where <NOBR><CODE><<I>function-name</I>></CODE></NOBR> is the name of the
|
||||
function.
|
||||
This technically defines <NOBR><CODE><<I>function-name</I>></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’s internal
|
||||
‘<CODE>countLeadingZeros</CODE>’ 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’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.

<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’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’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.
|
||||
