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.

<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.)
|
||||||
|
|
||||||
|

<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>

|
||||||
|
|
||||||
|
<UL>
|
||||||
|
|
||||||
|
<LI>
|
||||||
|
Implemented the common <NOBR>16-bit</NOBR> “half-precision”
|
||||||
|
floating-point format (<CODE>float16_t</CODE>).
|
||||||
|
|
||||||

<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><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
|
||||||

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.

For the example targets,

All of the supplied target directories are merely examples that may or may not

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,

</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.

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.

<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.
|
||||||
|
<DT><CODE>SOFTFLOAT_FAST_DIV32TO16</CODE>
|

|
<DD>
|
||||||
|
Can be defined to indicate that the target’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’s division operator

dividing a <NOBR>64-bit</NOBR> unsigned integer by a <NOBR>32-bit</NOBR>
|

<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.

<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
|

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.

|
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.
|
||||||
|
</P>

||||||

|
||||||

||||||
|
<H2>8. Contact Information</H2>
|
||||||

||||||
