This flag adds the standard library/device/BOOPSI functions to the
list of function entries to process. Possible values are \fBnone\fR,

Sets a function name prefix for the local library functions when
generating gatestubs or libproto files.
.IP "\fB\-\-sdi\fR" 8
.IX Item "--sdi"

Generate an old-style \s-1FD\s0 file.
.IP "\fBfunctable\fR" 4
.IX Item "functable"
Generate a list of function names suitable for inclusion in a library

Generate C library stubs suitable to be compiled and archived into
\&\fIlibamiga.a\fR, \fIlibamigastubs.a\fR or
\&\fIlib\fI<module>\fI.a\fR. Using the \fB\f(CB%f\fB\fR escape sequence in the

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIsfdc\fR is an open source replacement for Amiga, Inc.'s \fIsfd\fR tool,
distributed with \fB\s-1NDK 3.9\s0\fR. It is also an replacement for
\&\fIfd2inline\fR from GeekGadgets and the MorphOS team, later improved to
death by Martin Blom. It's now a complete mess and needs a
replacement. \s-1SFD\s0 files and \fIsfdc\fR might to be a good start.
.PP
For developers using \fIgcc\fR, \fIsfdc\fR aims to handle all your needs
when it comes to libraries, devices, datatypes, \s-1BOOPSI\s0 classes or
similar modules. \fIsfdc\fR can also generate \fI\s-1SAS/C\s0\fR, \fI\s-1DICE\s0\fR and
\&\fIStorm C\fR files for end users of such modules.
.PP
The basis for all work performed by \fIsfdc\fR is the \fB\s-1SFD\s0\fR file, which
contains all required information about the module and the functions
provided. From this information, \fIsfdc\fR can:
.IP "\(bu" 4
Generate an old-style \fB\s-1FD\s0\fR file for futher processing with other tools.
.IP "\(bu" 4
Generate a \fBC prototype file\fR, such as those normally found in the
\&\fIInclude/clib/\fR directory.
.IP "\(bu" 4
Generate \fIgcc\fR \fBinlines\fR (actually preprocessor macros) or
\&\fBpragmas\fR for direct library function calls (without going via
library stubs).
.IP "\(bu" 4
Generate the \fIInclude/proto/\fR file, which includes the
\&\fIInclude/clib/\fR file and either the inlines or pragmas.
.IP "\(bu" 4
Generate an \fBassembler \s-1LVO\s0\fR file, which contains the library offset
of all functions in the library.
.IP "\(bu" 4
Generate \fBC stubs\fR, which can be compiled and archived into a stub
library. It can also generate auto-open and auto-close code.
.IP "\(bu" 4
Generate library \fBgateway stubs\fR, which can be used as part of your
module as glue between the module function table and your C functions.
.PP
Additionally, \fIsfdc\fR does all this for several Amiga-like operating
systems: traditional \fBAmigaOS\fR, native \fBAmithlon\fR, \fB\s-1AROS\s0\fR and
\&\fBMorphOS\fR.
.PP
\&\fIsfdc\fR uses \fIautoconf\fR style identifies for the operating systems,
making it easy to generate the correct output. Just make sure
\&\fIconfigure.in\fR contains the \fB\s-1AC_CANONICAL_SYSTEM\s0\fR command and use
\&\fB\f(CB@host\fB@\fR in your \fIMakefile.in\fR. Using \fIautoconf\fR and \fIsfdc\fR, it's
easy to make for example a library that can be compiled or
cross-compiiled for any of the mentioned architectures.

\&\fB1.0 (2003\-07\-27)\fR
.Sp
Initial release.
.IP "\(bu" 4
\&\fB1.1 (2003\-12\-22)\fR
.Sp
Added workaround for workbench.library (base name is \*(L"wb\*(R").
Added AmigaOS 4 support.
Added the \fB\-\-addvectors\fR switch.
.IP "\(bu" 4
\&\fB1.2 (2004\-06\-16)\fR

Generates files for mathieeedoub*, though probably broken. Well they
are the same as fd2inline generates at least.
.IP "\(bu" 4
\&\fB1.2a (2004\-06\-20)\fR
.Sp
Replace \s-1AROS_LP\s0 with \s-1AROS_LD.\s0 Because it is guaranteed to define the
function prototype. [verhaegs]
.IP "\(bu" 4
\&\fB1.3 (2004\-11\-12)\fR
.Sp
Correctly handle the argument \f(CW\*(C`type **arg\*(C'\fR, where there is no
whitespace between the argument type and the argument name.
.IP "\(bu" 4
Correctly handle the prototype \f(CW\*(C`void function (void)\*(C'\fR, were there is
a whitespace between the function name and the parenthesis and \*(L"void\*(R"
is used to indicate no arguments.
.IP "\(bu" 4
Replace \f(CW\*(C`\-\*(C'\fR with \f(CW\*(C`_\*(C'\fR in base/library name.
.IP "\(bu" 4
New special keyword for register specification (in addition to \fBsysv\fR
and \fBbase\fR): \fBautoreg\fR, which automatically allocates m68k registers
for the arguments.
.IP "\(bu" 4
\&\fBsysv\fR now works correctly with varargs functions. \fBsysv\fR combined
with \fBgatestubs\fR work for m68k and i386 only for now. For \s-1AROS\s0
targets in \fBmacros\fR, the correct \s-1AROS\s0 macro is used to fetch the
function to be called.
.IP "\(bu" 4
New \fB\-\-mode\fR: \fBfunctable\fR. For proper code generation in \s-1AROS,\s0 make
sure gateprotos are included before you include the functable.
.IP "\(bu" 4
\&\fBproto\fR files now include \fIInclude/defines/\fR files when used in \s-1AROS.\s0
.IP "\(bu" 4
\&\fB1.4 (2005\-09\-23)\fR
.Sp
Added AmigaOS 4\-style interfaces (\*(C+ only for non\-OS4 targets, and
without implementation).
.IP "\(bu" 4
The library base in the \fBproto\fR file is now defined for AmigaOS 4
too.
.IP "\(bu" 4
AmigaOS 4 \fBclib\fR files now add \fB_\|_attribute_\|_((linearvarargs))\fR to
varargs functions.
.IP "\(bu" 4
Added AmigaOS 4 support for \fBstubs\fR files.
.IP "\(bu" 4
Added support for the 'iptr' gcc attribute.

Added \fB_\|_SFDC_FUNCTABLE_M68K_\|_\fR check in the \fBfunctable\fR mode.
.IP "\(bu" 4
Added m68k stub functions to AmigaOS 4's \fBgatestubs\fR and
\&\fBgateproto\fR.
.IP "\(bu" 4
Added the \fBautoopen\fR mode.
