to src/prep_cif.c. Introduced ffi_prep_cif_machdep().
--- libffi/src/mips -------------------------------------------------------
Tue Feb 17 17:18:07 1998 Anthony Green <green@hoser.cygnus.com>
* o32.S: Fixed typo in comment.
* ffi.c (ffi_prep_cif_machdep): Fixed argument processing.
Thu May 8 16:53:58 1997 Anthony Green <green@hoser.cygnus.com>
* o32.s, n32.s: Wrappers for SGI tool support.
* objects.mak: Removed.
Tue Oct 29 14:37:45 1996 Anthony Green <green@rtl.cygnus.com>
* ffi.c (ffi_prep_args): Changed int z to size_t z.
Tue Oct 15 13:17:25 1996 Anthony Green <green@hoser.cygnus.com>
* n32.S: Fixed bad stack munging.
* ffi.c: Moved prototypes for ffi_call_?32() to here from
ffi_mips.h because extended_cif is not defined in ffi_mips.h.
Mon Oct 14 12:42:02 1996 Anthony Green <green@rtl.cygnus.com>
* ffi.c: Interface changes based on feedback from Jim Blandy.
Thu Oct 10 11:22:16 1996 Anthony Green <green@rtl.cygnus.com>
* n32.S, ffi.c: Lots of changes to support passing and
returning structures with the n32 calling convention.
* n32.S: Fixed fn pointer bug.
* ffi.c (ffi_prep_cif_machdep): Fix for o32 structure
return values.
(ffi_prep_args): Fixed n32 structure passing when structures
partially fit in registers.
Wed Oct 9 13:49:25 1996 Anthony Green <green@rtl.cygnus.com>
* objects.mak: Added n32.o.
* n32.S: Created.
* ffi.c (ffi_prep_args): Added magic to support proper
n32 processing.
Tue Oct 8 10:37:35 1996 Anthony Green <green@rtl.cygnus.com>
* ffi.c: Moved ffi_type definitions to types.c.
(ffi_prep_args): Fixed type promotion bug.
* o32.S: This code is only built for o32 compiles.
A lot of the #define cruft has moved to ffi_mips.h.
* ffi.c (ffi_prep_cif_machdep): Fixed arg flags. Second arg
is only processed if the first is either a float or double.
Mon Oct 7 15:33:59 1996 Anthony Green <green@rtl.cygnus.com>
* o32.S: Modified to compile under each of o32, n32 and n64.
* ffi.c (FFI_*_TYPEDEF): Removed redundant ';'
Fri Oct 4 09:53:25 1996 Anthony Green <green@hoser.cygnus.com>
* ffi.c (ffi_call): Removed FFI_ABI arg, and swapped
remaining args.
Wed Oct 2 17:41:22 1996 Anthony Green <green@rtl.cygnus.com>
* o32.S: Removed crufty definitions.
Wed Oct 2 12:53:42 1996 Anthony Green <green@hoser.cygnus.com>
* ffi.c (ffi_prep_cif): cif->rvalue no longer initialized to NULL.
(ffi_prep_cif_machdep): Moved all machine independent cif processing
to src/prep_cif.c. Introduced ffi_prep_cif_machdep. Return types
of FFI_TYPE_STRUCT are no different than FFI_TYPE_INT.
Tue Oct 1 17:11:02 1996 Anthony Green <green@rtl.cygnus.com>
* ffi.c, o32.S, object.mak: Created
--- libffi/src/sparc ------------------------------------------------------
Tue Feb 24 16:33:18 1998 Anthony Green <green@hoser.cygnus.com>
* ffi.c (ffi_prep_args): Added long double support.
Thu May 8 16:53:58 1997 Anthony Green <green@hoser.cygnus.com>
* objects.mak: Removed.
Thu May 1 16:07:56 1997 Anthony Green <green@hoser.cygnus.com>
* v8.S: Fixed minor portability problem reported by
Russ McManus <mcmanr@eq.gs.com>.
Tue Nov 26 14:12:43 1996 Anthony Green <green@csk3.cygnus.com>
* v8.S: Used STACKFRAME define elsewhere.
* ffi.c (ffi_prep_args): Zero out space when USING_PURIFY
is set.
(ffi_prep_cif_machdep): Allocate the correct stack frame
space for functions with < 6 args.
Tue Oct 29 15:08:55 1996 Anthony Green <green@rtl.cygnus.com>
* ffi.c (ffi_prep_args): int z is now size_t z.
Mon Oct 14 13:31:24 1996 Anthony Green <green@rtl.cygnus.com>
* v8.S (ffi_call_V8): Gordon rewrites this again. It looks
great now.
* ffi.c (ffi_call): The comment about hijacked registers
is no longer valid after gordoni hacked v8.S.
* v8.S (ffi_call_V8): Rewrote with gordoni. Much simpler.
* v8.S, ffi.c: ffi_call() had changed to accept more than
two args, so v8.S had to change (because it hijacks incoming
arg registers).
* ffi.c: Interface changes based on feedback from Jim Blandy.
Thu Oct 10 17:48:16 1996 Anthony Green <green@rtl.cygnus.com>
* ffi.c, v8.S, objects.mak: Created.

README for libffi-2.00
libffi-2.00 has not been released yet! This is a development snapshot!
libffi-1.20 was released on [SOME FUTURE DAY]. Check the libffi web
page for updates: <URL:http://sourceware.cygnus.com/libffi/>.
What is libffi?
===============
Compilers for high level languages generate code that follow certain
conventions. These conventions are necessary, in part, for separate
compilation to work. One such convention is the "calling
convention". The "calling convention" is essentially a set of
assumptions made by the compiler about where function arguments will
be found on entry to a function. A "calling convention" also specifies
where the return value for a function is found.
Some programs may not know at the time of compilation what arguments
are to be passed to a function. For instance, an interpreter may be
told at run-time about the number and types of arguments used to call
a given function. Libffi can be used in such programs to provide a
bridge from the interpreter program to compiled code.
The libffi library provides a portable, high level programming
interface to various calling conventions. This allows a programmer to
call any function specified by a call interface description at run
time.
Ffi stands for Foreign Function Interface. A foreign function
interface is the popular name for the interface that allows code
written in one language to call code written in another language. The
libffi library really only provides the lowest, machine dependent
layer of a fully featured foreign function interface. A layer must
exist above libffi that handles type conversions for values passed
between the two languages.
Supported Platforms and Prerequisites
=====================================
Libffi has been ported to:
SunOS 4.1.3 & Solaris 2.x (Sparc v8)
Irix 5.3 & 6.2 (System V/o32 & n32)
Intel x86 - Linux (System V ABI)
Alpha - Linux and OSF/1
m68k - Linux (System V ABI)
PowerPC - Linux (System V ABI)
ARM - Linux (System V ABI)
Libffi has been tested with the egcs 1.0.2 gcc compiler. Chances are
that other versions will work. Libffi has also been built and tested
with the SGI compiler tools.
On PowerPC, the tests failed (see the note below).
You must use GNU make to build libffi. SGI's make will not work.
Sun's probably won't either.
If you port libffi to another platform, please let me know! I assume
that some will be easy (x86 NetBSD), and others will be more difficult
(HP, AIX).
Installing libffi
=================
[Note: before actually performing any of these installation steps,
you may wish to read the "Platform Specific Notes" below.]
First you must configure the distribution for your particular
system. Go to the directory you wish to build libffi in and run the
"configure" program found in the root directory of the libffi source
distribution.
You may want to tell configure where to install the libffi library and
header files. To do that, use the --prefix configure switch. Libffi
will install under /usr/local by default.
If you want to enable extra run-time debugging checks use the the
--enable-debug configure switch. This is useful when your program dies
mysteriously while using libffi.
Another useful configure switch is --enable-purify-safety. Using this
will add some extra code which will suppress certain warnings when you
are using Purify with libffi. Only use this switch when using
Purify, as it will slow down the library.
Configure has many other options. Use "configure --help" to see them all.
Once configure has finished, type "make". Note that you must be using
GNU make. SGI's make will not work. Sun's probably won't either.
You can ftp GNU make from prep.ai.mit.edu:/pub/gnu.
To ensure that libffi is working as advertised, type "make test".
To install the library and header files, type "make install".
Using libffi
============
The Basics
----------
Libffi assumes that you have a pointer to the function you wish to
call and that you know the number and types of arguments to pass it,
as well as the return type of the function.
The first thing you must do is create an ffi_cif object that matches
the signature of the function you wish to call. The cif in ffi_cif
stands for Call InterFace. To prepare a call interface object, use the
following function:
ffi_status ffi_prep_cif(ffi_cif *cif, ffi_abi abi,
unsigned int nargs,
ffi_type *rtype, ffi_type **atypes);
CIF is a pointer to the call interface object you wish
to initialize.
ABI is an enum that specifies the calling convention
to use for the call. FFI_DEFAULT_ABI defaults
to the system's native calling convention. Other
ABI's may be used with care. They are system
specific.
NARGS is the number of arguments this function accepts.
libffi does not yet support vararg functions.
RTYPE is a pointer to an ffi_type structure that represents
the return type of the function. Ffi_type objects
describe the types of values. libffi provides
ffi_type objects for many of the native C types:
signed int, unsigned int, signed char, unsigned char,
etc. There is also a pointer ffi_type object and
a void ffi_type. Use &ffi_type_void for functions that
don't return values.
ATYPES is a vector of ffi_type pointers. ARGS must be NARGS long.
If NARGS is 0, this is ignored.
ffi_prep_cif will return a status code that you are responsible
for checking. It will be one of the following:
FFI_OK - All is good.
FFI_BAD_TYPEDEF - One of the ffi_type objects that ffi_prep_cif
came across is bad.
Before making the call, the VALUES vector should be initialized
with pointers to the appropriate argument values.
To call the the function using the initialized ffi_cif, use the
ffi_call function:
void ffi_call(ffi_cif *cif, void *fn, void *rvalue, void **avalues);
CIF is a pointer to the ffi_cif initialized specifically
for this function.
FN is a pointer to the function you want to call.
RVALUE is a pointer to a chunk of memory that is to hold the
result of the function call. Currently, it must be
at least one word in size (except for the n32 version
under Irix 6.x, which must be a pointer to an 8 byte
aligned value (a long long). It must also be at least
word aligned (depending on the return type, and the
system's alignment requirements). If RTYPE is
&ffi_type_void, this is ignored. If RVALUE is NULL,
the return value is discarded.
AVALUES is a vector of void* that point to the memory locations
holding the argument values for a call.
If NARGS is 0, this is ignored.
If you are expecting a return value from FN it will have been stored
at RVALUE.
An Example
----------
Here is a trivial example that calls puts() a few times.
#include <stdio.h>
#include <ffi.h>
int main()
{
ffi_cif cif;
ffi_type *args[1];
void *values[1];
char *s;
int rc;
/* Initialize the argument info vectors */
args[0] = &ffi_type_uint;
values[0] = &s;
/* Initialize the cif */
if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1,
&ffi_type_uint, args) == FFI_OK)
{
s = "Hello World!";
ffi_call(&cif, puts, &rc, values);
/* rc now holds the result of the call to puts */
/* values holds a pointer to the function's arg, so to
call puts() again all we need to do is change the
value of s */
s = "This is cool!";
ffi_call(&cif, puts, &rc, values);
}
return 0;
}
Aggregate Types
---------------
Although libffi has no special support for unions or bit-fields, it is
perfectly happy passing structures back and forth. You must first
describe the structure to libffi by creating a new ffi_type object
for it. Here is the definition of ffi_type:
typedef struct _ffi_type
{
unsigned size;
short alignment;
short type;
struct _ffi_type **elements;
} ffi_type;
All structures must have type set to FFI_TYPE_STRUCT. You may set
size and alignment to 0. These will be calculated and reset to the
appropriate values by ffi_prep_cif().
elements is a NULL terminated array of pointers to ffi_type objects
that describe the type of the structure elements. These may, in turn,
be structure elements.
The following example initializes a ffi_type object representing the
tm struct from Linux's time.h:
struct tm {
int tm_sec;
int tm_min;
int tm_hour;
int tm_mday;
int tm_mon;
int tm_year;
int tm_wday;
int tm_yday;
int tm_isdst;
/* Those are for future use. */
long int __tm_gmtoff__;
__const char *__tm_zone__;
};
{
ffi_type tm_type;
ffi_type *tm_type_elements[12];
int i;
tm_type.size = tm_type.alignment = 0;
tm_type.elements = &tm_type_elements;
for (i = 0; i < 9; i++)
tm_type_elements[i] = &ffi_type_sint;
tm_type_elements[9] = &ffi_type_slong;
tm_type_elements[10] = &ffi_type_pointer;
tm_type_elements[11] = NULL;
/* tm_type can now be used to represent tm argument types and
return types for ffi_prep_cif() */
}
Platform Specific Notes
=======================
Intel x86
---------
There are no known problems with the x86 port.
Sun Sparc - SunOS 4.1.3 & Solaris 2.x
-------------------------------------
There's a bug in the structure passing code for sparc processors.
Struct arguments that are passed in value actually end up being passed
by reference. This will be fixed Real Soon Now.
"long long" values are not supported yet.
You must use GNU Make to build libffi on Sun platforms.
MIPS - Irix 5.3 & 6.x
---------------------
Irix 6.2 and better supports three different calling conventions: o32,
n32 and n64. Currently, libffi only supports both o32 and n32 under
Irix 6.x, but only o32 under Irix 5.3. Libffi will automatically be
configured for whichever calling convention it was built for.
By default, the configure script will try to build libffi with the GNU
development tools. To build libffi with the SGI development tools, set
the environment variable CC to either "cc -32" or "cc -n32" before
running configure under Irix 6.x (depending on whether you want an o32
or n32 library), or just "cc" for Irix 5.3.
With the n32 calling convention, when returning structures smaller
than 16 bytes, be sure to provide an RVALUE that is 8 byte aligned.
Here's one way of forcing this:
double struct_storage[2];
my_small_struct *s = (my_small_struct *) struct_storage;
/* Use s for RVALUE */
If you don't do this you are liable to get spurious bus errors.
"long long" values are not supported yet.
You must use GNU Make to build libffi on SGI platforms.
ARM - System V ABI
------------------
The ARM port was performed on a NetWinder running ARM Linux ELF
(2.0.31) and gcc 2.8.1. config.sub still does not recognize the
machine name sa110-unknown-linux-gnu (currently returned by
NetWinder). In the mean time the package can be configured by running
'configure arm-linux'.
PowerPC System V ABI
--------------------
There are two `System V ABI's which libffi implements for PowerPC.
They differ only in how small structures are returned from functions.
In the FFI_SYSV version, structures that are 8 bytes or smaller are
returned in registers. This is what GCC does when it is configured
for solaris, and is what the System V ABI I have (dated September
1995) says.
In the FFI_GCC_SYSV version, all structures are returned the same way:
by passing a pointer as the first argument to the function. This is
what GCC does when it is configured for linux or a generic sysv
target.
EGCS 1.0.1 (and probably other versions of EGCS/GCC) also has a
inconsistency with the SysV ABI: When a procedure is called with many
floating-point arguments, some of them get put on the stack. They are
all supposed to be stored in double-precision format, even if they are
only single-precision, but EGCS stores single-precision arguments as
single-precision anyway. This causes one test to fail (the `many
arguments' test).
What's With The Crazy Comments?
===============================
You might notice a number of cryptic comments in the code, delimited
by /*@ and @*/. These are annotations read by the program LCLint, a
tool for statically checking C programs. You can read all about it at
<http://larch-www.lcs.mit.edu:8001/larch/lclint/index.html>.

Usage: $progname [OPTION]... [HOST [LTMAIN]]
Generate a system-specific libtool script.
--debug enable verbose shell tracing
--disable-shared do not build shared libraries
--disable-static do not build static libraries
--disable-fast-install do not optimize for fast installation
--enable-dlopen enable dlopen support
--enable-dlopen-self enable support for dlopening programs
--help display this help and exit
--no-verify do not verify that HOST is a valid host type
-o, --output=FILE specify the output file [default=$default_ofile]
--quiet same as \`--silent'
--silent do not print informational messages
--srcdir=DIR find \`config.guess' in DIR
--version output version information and exit
--with-gcc assume that the GNU C compiler will be used
--with-gnu-ld assume that the C compiler uses the GNU linker
--disable-lock disable file locking
--cache-file=FILE configure cache file
LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
that provides basic libtool functionality.
HOST is the canonical host system name [default=guessed].
