Bug 1659906 - Upgrade libffi to version 3.3. r=froydnj

Browse Source 
All the patches previously applied, except the one from bug 1279096,
are either irrelevant (as pertaining to changes to the upstream build
system we don't use anymore), were applied upstream, or the issue they
fixed were fixed differently upstream.

Two additional patches, sent upstream as
https://github.com/libffi/libffi/pull/579 and
https://github.com/libffi/libffi/pull/580, are needed to fix our build
with, respectively, mingw-clang and GCC.

Our build system is adjusted according to upstream's configure.ac
and configure.host.

Modifications to upstream libffi needed for the Mozilla build:
* Clear INFO_DEPS so that builds don't fail when makeinfo isn't present.
- This can be removed if https://github.com/atgreen/libffi/issues/111 is fixed.
* Various workarounds for pymake bugs.
- Once pymake support is fully deprecated, hunks 2-4 be safely removed.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

Status
======
libffi-3.1 was released on May 11, 2014. Check the libffi web page
for updates: <URL:http://sourceware.org/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.

Installing libffi
=================
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.
If you're building libffi directly from version control, configure won't
exist yet; run ./autogen.sh first.
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.
It's also possible to build libffi on Windows platforms with
Microsoft's Visual C++ compiler. In this case, use the msvcc.sh
wrapper script during configuration like so:
path/to/configure CC=path/to/msvcc.sh CXX=path/to/msvcc.sh LD=link CPP="cl -nologo -EP"
For 64-bit Windows builds, use CC="path/to/msvcc.sh -m64" and
CXX="path/to/msvcc.sh -m64". You may also need to specify --build
appropriately.
It is also possible to build libffi on Windows platforms with the LLVM
project's clang-cl compiler, like below:
path/to/configure CC="path/to/msvcc.sh -clang-cl" CXX="path/to/msvcc.sh -clang-cl" LD=link CPP="clang-cl -EP"
When building with MSVC under a MingW environment, you may need to
remove the line in configure that sets 'fix_srcfile_path' to a 'cygpath'
command. ('cygpath' is not present in MingW, and is not required when
using MingW-style paths.)
For iOS builds, the 'libffi.xcodeproj' Xcode project is available.
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. You can ftp GNU make from ftp.gnu.org:/pub/gnu/make .
To ensure that libffi is working as advertised, type "make check".
This will require that you have DejaGNU installed.
To install the library and header files, type "make install".

libffi-3.3 was released on November 23, 2019. Check the libffi web
page for updates: <URL:http://sourceware.org/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.

Installing libffi
=================
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. Note that building libffi requires a C99 compatible
compiler.
If you're building libffi directly from git hosted sources, configure
won't exist yet; run ./autogen.sh first. This will require that you
install autoconf, automake and libtool.
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.
If you don't want to build documentation, use the ``--disable-docs``
configure switch.
It's also possible to build libffi on Windows platforms with
Microsoft's Visual C++ compiler. In this case, use the msvcc.sh
wrapper script during configuration like so:
path/to/configure CC=path/to/msvcc.sh CXX=path/to/msvcc.sh LD=link CPP="cl -nologo -EP" CPPFLAGS="-DFFI_BUILDING_DLL"
For 64-bit Windows builds, use ``CC="path/to/msvcc.sh -m64"`` and
``CXX="path/to/msvcc.sh -m64"``. You may also need to specify
``--build`` appropriately.
It is also possible to build libffi on Windows platforms with the LLVM
project's clang-cl compiler, like below:
path/to/configure CC="path/to/msvcc.sh -clang-cl" CXX="path/to/msvcc.sh -clang-cl" LD=link CPP="clang-cl -EP"
When building with MSVC under a MingW environment, you may need to
remove the line in configure that sets 'fix_srcfile_path' to a 'cygpath'
command. ('cygpath' is not present in MingW, and is not required when
using MingW-style paths.)
To build static library for ARM64 with MSVC using visual studio solution, msvc_build folder have
aarch64/Ffi_staticLib.sln
required header files in aarch64/aarch64_include/
SPARC Solaris builds require the use of the GNU assembler and linker.
Point ``AS`` and ``LD`` environment variables at those tool prior to
configuration.
For iOS builds, the ``libffi.xcodeproj`` Xcode project is available.
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. You can ftp GNU make from ftp.gnu.org:/pub/gnu/make .
To ensure that libffi is working as advertised, type "make check".
This will require that you have DejaGNU installed.
To install the library and header files, type ``make install``.

In most situations, 'libffi' will handle promotion according to the
ABI. However, for historical reasons, there is a special case with
return values that must be handled by your code. In particular,
for integral (not 'struct') types that are narrower than the system
register size, the return value will be widened by 'libffi'.
'libffi' provides a type, 'ffi_arg', that can be used as the return
type. For example, if the CIF was defined with a return type of
'char', 'libffi' will try to store a full 'ffi_arg' into the return
value.

------------------------
'libffi' will set the 'size' and 'alignment' fields of an 'ffi_type'

You might expect that you can simply read these fields for a type

depending on the chosen ABI.
* The size and alignment of a new structure type will not be set by

* A structure type cannot be shared across ABIs. Instead each ABI
needs its own copy of the structure type.
So, before examining these fields, it is safest to pass the
'ffi_type' object to 'ffi_prep_cif' or 'ffi_get_struct_offsets' first.
This function will do all the needed setup.
ffi_type *desired_type;
ffi_abi desired_abi;
...
ffi_cif cif;
if (ffi_prep_cif (&cif, desired_abi, 0, desired_type, NULL) == FFI_OK)
{
size_t size = desired_type->size;
unsigned short alignment = desired_type->alignment;
}
'libffi' also provides a way to get the offsets of the members of a
structure.
-- Function: ffi_status ffi_get_struct_offsets (ffi_abi abi, ffi_type
*struct_type, size_t *offsets)
Compute the offset of each element of the given structure type.
ABI is the ABI to use; this is needed because in some cases the
layout depends on the ABI.
OFFSETS is an out parameter. The caller is responsible for
providing enough space for all the results to be written - one
element per element type in STRUCT_TYPE. If OFFSETS is 'NULL',
then the type will be laid out but not otherwise modified. This
can be useful for accessing the type's size or layout, as mentioned
above.
This function returns 'FFI_OK' on success; 'FFI_BAD_ABI' if ABI is
invalid; or 'FFI_BAD_TYPEDEF' if STRUCT_TYPE is invalid in some
way. Note that only 'FFI_STRUCT' types are valid here.

2.3.4 Arrays, Unions, and Enumerations
--------------------------------------
2.3.4.1 Arrays
..............
'libffi' does not have direct support for arrays or unions. However,
they can be emulated using structures.
To emulate an array, simply create an 'ffi_type' using
'FFI_TYPE_STRUCT' with as many members as there are elements in the
array.
ffi_type array_type;
ffi_type **elements
int i;
elements = malloc ((n + 1) * sizeof (ffi_type *));
for (i = 0; i < n; ++i)
elements[i] = array_element_type;
elements[n] = NULL;
array_type.size = array_type.alignment = 0;
array_type.type = FFI_TYPE_STRUCT;
array_type.elements = elements;
Note that arrays cannot be passed or returned by value in C -
structure types created like this should only be used to refer to
members of real 'FFI_TYPE_STRUCT' objects.
However, a phony array type like this will not cause any errors from
'libffi' if you use it as an argument or return type. This may be
confusing.
2.3.4.2 Unions
..............
A union can also be emulated using 'FFI_TYPE_STRUCT'. In this case,
however, you must make sure that the size and alignment match the real
requirements of the union.
One simple way to do this is to ensue that each element type is laid
out. Then, give the new structure type a single element; the size of
the largest element; and the largest alignment seen as well.
This example uses the 'ffi_prep_cif' trick to ensure that each
element type is laid out.
ffi_abi desired_abi;
ffi_type union_type;
ffi_type **union_elements;
int i;
ffi_type element_types[2];
element_types[1] = NULL;
union_type.size = union_type.alignment = 0;
union_type.type = FFI_TYPE_STRUCT;
union_type.elements = element_types;
for (i = 0; union_elements[i]; ++i)
{
ffi_cif cif;
if (ffi_prep_cif (&cif, desired_abi, 0, union_elements[i], NULL) == FFI_OK)
{
if (union_elements[i]->size > union_type.size)
{
union_type.size = union_elements[i];
size = union_elements[i]->size;
}
if (union_elements[i]->alignment > union_type.alignment)
union_type.alignment = union_elements[i]->alignment;
}
}
2.3.4.3 Enumerations
....................
'libffi' does not have any special support for C 'enum's. Although any
given 'enum' is implemented using a specific underlying integral type,
exactly which type will be used cannot be determined by 'libffi' - it
may depend on the values in the enumeration or on compiler flags such as
'-fshort-enums'. *Note (gcc)Structures unions enumerations and
bit-fields implementation::, for more information about how GCC handles
enumerations.

2.3.6 Complex Types
-------------------
'libffi' supports the complex types defined by the C99 standard
('_Complex float', '_Complex double' and '_Complex long double' with the
built-in type descriptors 'ffi_type_complex_float',
'ffi_type_complex_double' and 'ffi_type_complex_longdouble'.
Custom complex types like '_Complex int' can also be used. An
'ffi_type' object has to be defined to describe the complex type to
'libffi'.
-- Data type: ffi_type
'size_t size'
This must be manually set to the size of the complex type.
'unsigned short alignment'
This must be manually set to the alignment of the complex
type.
'unsigned short type'
For a complex type, this must be set to 'FFI_TYPE_COMPLEX'.
'ffi_type **elements'
This is a 'NULL'-terminated array of pointers to 'ffi_type'
objects. The first element is set to the 'ffi_type' of the
complex's base type. The second element must be set to
'NULL'.
The section *note Complex Type Example:: shows a way to determine the
'size' and 'alignment' members in a platform independent way.
For platforms that have no complex support in 'libffi' yet, the
functions 'ffi_prep_cif' and 'ffi_prep_args' abort the program if they
encounter a complex type.

File: libffi.info, Node: Complex Type Example, Prev: Complex, Up: Types
2.3.7 Complex Type Example
--------------------------
This example demonstrates how to use complex types:
#include <stdio.h>
#include <ffi.h>
#include <complex.h>
void complex_fn(_Complex float cf,
_Complex double cd,
_Complex long double cld)
{
printf("cf=%f+%fi\ncd=%f+%fi\ncld=%f+%fi\n",
(float)creal (cf), (float)cimag (cf),
(float)creal (cd), (float)cimag (cd),
(float)creal (cld), (float)cimag (cld));
}
int main()
{
ffi_cif cif;
ffi_type *args[3];
void *values[3];
_Complex float cf;
_Complex double cd;
_Complex long double cld;
/* Initialize the argument info vectors */
args[0] = &ffi_type_complex_float;
args[1] = &ffi_type_complex_double;
args[2] = &ffi_type_complex_longdouble;
values[0] = &cf;
values[1] = &cd;
values[2] = &cld;
/* Initialize the cif */
if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 3,
&ffi_type_void, args) == FFI_OK)
{
cf = 1.0 + 20.0 * I;
cd = 300.0 + 4000.0 * I;
cld = 50000.0 + 600000.0 * I;
/* Call the function */
ffi_call(&cif, (void (*)(void))complex_fn, 0, values);
}
return 0;
}
This is an example for defining a custom complex type descriptor for
compilers that support them:
/*
* This macro can be used to define new complex type descriptors
* in a platform independent way.
*
* name: Name of the new descriptor is ffi_type_complex_<name>.
* type: The C base type of the complex type.
*/
#define FFI_COMPLEX_TYPEDEF(name, type, ffitype) \
static ffi_type *ffi_elements_complex_##name [2] = { \
(ffi_type *)(&ffitype), NULL \
}; \
struct struct_align_complex_##name { \
char c; \
_Complex type x; \
}; \
ffi_type ffi_type_complex_##name = { \
sizeof(_Complex type), \
offsetof(struct struct_align_complex_##name, x), \
FFI_TYPE_COMPLEX, \
(ffi_type **)ffi_elements_complex_##name \
}
/* Define new complex type descriptors using the macro: */
/* ffi_type_complex_sint */
FFI_COMPLEX_TYPEDEF(sint, int, ffi_type_sint);
/* ffi_type_complex_uchar */
FFI_COMPLEX_TYPEDEF(uchar, unsigned char, ffi_type_uint8);
The new type descriptors can then be used like one of the built-in
type descriptors in the previous example.

=================
'libffi' is not completely thread-safe. However, many parts are, and if
you follow some simple rules, you can use it safely in a multi-threaded
program.
* 'ffi_prep_cif' may modify the 'ffi_type' objects passed to it. It
is best to ensure that only a single thread prepares a given
'ffi_cif' at a time.
* On some platforms, 'ffi_prep_cif' may modify the size and alignment
of some types, depending on the chosen ABI. On these platforms, if
you switch between ABIs, you must ensure that there is only one
call to 'ffi_prep_cif' at a time.
Currently the only affected platform is PowerPC and the only
affected type is 'long double'.

@samp{libffi}. @samp{libffi} provides a type, @code{ffi_arg}, that

@node Size and Alignment
@subsection Size and Alignment
@code{libffi} will set the @code{size} and @code{alignment} fields of
an @code{ffi_type} object for you. It does so using its knowledge of
the ABI.
You might expect that you can simply read these fields for a type that
has been laid out by @code{libffi}. However, there are some caveats.
@itemize @bullet
@item
The size or alignment of some of the built-in types may vary depending
on the chosen ABI.
@item
The size and alignment of a new structure type will not be set by
@code{libffi} until it has been passed to @code{ffi_prep_cif} or
@code{ffi_get_struct_offsets}.
@item
A structure type cannot be shared across ABIs. Instead each ABI needs
its own copy of the structure type.
@end itemize
So, before examining these fields, it is safest to pass the
@code{ffi_type} object to @code{ffi_prep_cif} or
@code{ffi_get_struct_offsets} first. This function will do all the
needed setup.
@example
ffi_type *desired_type;
ffi_abi desired_abi;
@dots{}
ffi_cif cif;

a structure.
@findex ffi_get_struct_offsets
@defun ffi_status ffi_get_struct_offsets (ffi_abi abi, ffi_type *struct_type, size_t *offsets)
Compute the offset of each element of the given structure type.
@var{abi} is the ABI to use; this is needed because in some cases the
layout depends on the ABI.
@var{offsets} is an out parameter. The caller is responsible for
providing enough space for all the results to be written -- one
element per element type in @var{struct_type}. If @var{offsets} is
@code{NULL}, then the type will be laid out but not otherwise
modified. This can be useful for accessing the type's size or layout,
as mentioned above.
This function returns @code{FFI_OK} on success; @code{FFI_BAD_ABI} if
@var{abi} is invalid; or @code{FFI_BAD_TYPEDEF} if @var{struct_type}
is invalid in some way. Note that only @code{FFI_STRUCT} types are

for (i = 0; i < n; ++i)
elements[i] = array_element_type;
elements[n] = NULL;
array_type.size = array_type.alignment = 0;
array_type.type = FFI_TYPE_STRUCT;
array_type.elements = elements;
@end example
Note that arrays cannot be passed or returned by value in C --
structure types created like this should only be used to refer to
members of real @code{FFI_TYPE_STRUCT} objects.
However, a phony array type like this will not cause any errors from
@samp{libffi} if you use it as an argument or return type. This may
be confusing.
@subsubsection Unions
A union can also be emulated using @code{FFI_TYPE_STRUCT}. In this
case, however, you must make sure that the size and alignment match
the real requirements of the union.
One simple way to do this is to ensue that each element type is laid
out. Then, give the new structure type a single element; the size of
the largest element; and the largest alignment seen as well.
This example uses the @code{ffi_prep_cif} trick to ensure that each
element type is laid out.
@example
ffi_abi desired_abi;
ffi_type union_type;
ffi_type **union_elements;
int i;
ffi_type element_types[2];
element_types[1] = NULL;
union_type.size = union_type.alignment = 0;
union_type.type = FFI_TYPE_STRUCT;
union_type.elements = element_types;
for (i = 0; union_elements[i]; ++i)
@{
ffi_cif cif;
if (ffi_prep_cif (&cif, desired_abi, 0, union_elements[i], NULL) == FFI_OK)
@{
if (union_elements[i]->size > union_type.size)
@{
union_type.size = union_elements[i];
size = union_elements[i]->size;
@}
if (union_elements[i]->alignment > union_type.alignment)
union_type.alignment = union_elements[i]->alignment;
@}
@}
@end example
@subsubsection Enumerations
@code{libffi} does not have any special support for C @code{enum}s.
Although any given @code{enum} is implemented using a specific
underlying integral type, exactly which type will be used cannot be
determined by @code{libffi} -- it may depend on the values in the
enumeration or on compiler flags such as @option{-fshort-enums}.

@subsection Complex Types
@samp{libffi} supports the complex types defined by the C99
standard (@code{_Complex float}, @code{_Complex double} and
@code{_Complex long double} with the built-in type descriptors
@code{ffi_type_complex_float}, @code{ffi_type_complex_double} and
@code{ffi_type_complex_longdouble}.
Custom complex types like @code{_Complex int} can also be used.
An @code{ffi_type} object has to be defined to describe the
complex type to @samp{libffi}.
@tindex ffi_type
@deftp {Data type} ffi_type
@table @code
@item size_t size
This must be manually set to the size of the complex type.
@item unsigned short alignment
This must be manually set to the alignment of the complex type.
@item unsigned short type
For a complex type, this must be set to @code{FFI_TYPE_COMPLEX}.
@item ffi_type **elements
This is a @samp{NULL}-terminated array of pointers to
@code{ffi_type} objects. The first element is set to the
@code{ffi_type} of the complex's base type. The second element
must be set to @code{NULL}.
@end table
@end deftp
The section @ref{Complex Type Example} shows a way to determine
the @code{size} and @code{alignment} members in a platform
independent way.
For platforms that have no complex support in @code{libffi} yet,
the functions @code{ffi_prep_cif} and @code{ffi_prep_args} abort
the program if they encounter a complex type.

values[0] = &cf;
values[1] = &cd;
values[2] = &cld;
/* Initialize the cif */
if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 3,
&ffi_type_void, args) == FFI_OK)
@{
cf = 1.0 + 20.0 * I;
cd = 300.0 + 4000.0 * I;
cld = 50000.0 + 600000.0 * I;

ffi_call(&cif, (void (*)(void))complex_fn, 0, values);

@end example
This is an example for defining a custom complex type descriptor
for compilers that support them:
@example
/*
* This macro can be used to define new complex type descriptors
* in a platform independent way.
*
* name: Name of the new descriptor is ffi_type_complex_<name>.
* type: The C base type of the complex type.
*/
#define FFI_COMPLEX_TYPEDEF(name, type, ffitype) \
static ffi_type *ffi_elements_complex_##name [2] = @{ \
(ffi_type *)(&ffitype), NULL \
@}; \
struct struct_align_complex_##name @{ \
char c; \
_Complex type x; \
@}; \
ffi_type ffi_type_complex_##name = @{ \
sizeof(_Complex type), \
offsetof(struct struct_align_complex_##name, x), \
FFI_TYPE_COMPLEX, \
(ffi_type **)ffi_elements_complex_##name \
@}
/* Define new complex type descriptors using the macro: */
/* ffi_type_complex_sint */
FFI_COMPLEX_TYPEDEF(sint, int, ffi_type_sint);
/* ffi_type_complex_uchar */
FFI_COMPLEX_TYPEDEF(uchar, unsigned char, ffi_type_uint8);
@end example
The new type descriptors can then be used like one of the built-in
type descriptors in the previous example.

The basic API is described in the README file.
Most of the API is documented in doc/libffi.texi.
The raw API is designed to bypass some of the argument packing
and unpacking on architectures for which it can be avoided.
The raw API is designed to bypass some of the argument packing and
unpacking on architectures for which it can be avoided. Routines
are provided to emulate the raw API if the underlying platform
doesn't allow faster implementation.
The closure API allows interpreted functions to be packaged up
inside a C function pointer, so that they can be called as C functions,
with no understanding on the client side that they are interpreted.
It can also be used in other cases in which it is necessary to package
up a user specified parameter and a function pointer as a single
function pointer.
The closure API must be implemented in order to get its functionality,
e.g. for use by gij. Routines are provided to emulate the raw API
if the underlying platform doesn't allow faster implementation.
More details on the raw and cloure API can be found in:

# AX_GCC_X86_CPUID(OP)
# AX_GCC_X86_CPUID_COUNT(OP, COUNT)
#
# DESCRIPTION
#
# On Pentium and later x86 processors, with gcc or a compiler that has a
# compatible syntax for inline assembly instructions, run a small program
# that executes the cpuid instruction with input OP. This can be used to
# detect the CPU type.
# detect the CPU type. AX_GCC_X86_CPUID_COUNT takes an additional COUNT
# parameter that gets passed into register ECX before calling cpuid.
#
# On output, the values of the eax, ebx, ecx, and edx registers are stored
# as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable

#
# SYNOPSIS
#
# AX_REQUIRE_DEFINED(MACRO)
#
# DESCRIPTION
#
# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
# been defined and thus are available for use. This avoids random issues
# where a macro isn't expanded. Instead the configure script emits a
# non-fatal:
#
# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
#
# It's like AC_REQUIRE except it doesn't expand the required macro.
#
# Here's an example:
#
# AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

The maximum required argument stack size is provided,
ffi_call_SYSV() allocates that stack space then calls the
prepare_fn to populate register context and stack. The
argument passing registers are loaded from the register
context and the callee called, on return the register passing
register are saved back to the context. Our caller will
extract the return value from the final state of the saved
