@ -113,14 +137,20 @@ 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 --enable-shared --enable-static \
CC=path/to/msvcc.sh LD=link \
CPP=\"cl -nologo -EP\"
path/to/configure CC=path/to/msvcc.sh LD=link CPP=\"cl -nologo -EP\"
For 64-bit Windows builds, use CC="path/to/msvcc.sh -m64".
You may also need to specify --build appropriately. 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 prep.ai.mit.edu:/pub/gnu.
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.

# SYNOPSIS
#
# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
#
# DESCRIPTION
#
# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
# added in between.
#
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
# FLAG.
#
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

#
# SYNOPSIS
#
# AX_CC_MAXOPT
#
# DESCRIPTION
#
# Try to turn on "good" C optimization flags for various compilers and
# architectures, for some definition of "good". (In our case, good for
# FFTW and hopefully for other scientific codes. Modify as needed.)
#
# The user can override the flags by setting the CFLAGS environment
# variable. The user can also specify --enable-portable-binary in order to
# disable any optimization flags that might result in a binary that only
# runs on the host architecture.
#
# Note also that the flags assume that ANSI C aliasing rules are followed
# by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
# computations can be re-ordered as needed.
#
# Requires macros: AX_CHECK_COMPILE_FLAG, AX_COMPILER_VENDOR,
# AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

# SYNOPSIS
#
# AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
# AX_CXXFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
# AX_FCFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
#
# DESCRIPTION
#
# Try to find a compiler option that enables most reasonable warnings.
#
# For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
# is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
#
# Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
# HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
# Intel compilers. For a given compiler, the Fortran flags are much more
# experimental than their C equivalents.
#
# - $1 shell-variable-to-add-to : CFLAGS, CXXFLAGS, or FCFLAGS
# - $2 add-value-if-not-found : nothing
# - $3 action-if-found : add value to shellvariable
# - $4 action-if-not-found : nothing
#
# NOTE: These macros depend on AX_APPEND_FLAG.

# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
#
# DESCRIPTION
#
# Check whether the given FLAG works with the current language's compiler
# or gives an error. (Warnings, however, are ignored)
#
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
# success/failure.
#
# If EXTRA-FLAGS is defined, it is added to the current language's default
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
# force the compiler to issue an error when a bad flag is given.
#
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

# AX_CONFIGURE_ARGS
#
# DESCRIPTION
#
# Helper macro for AX_ENABLE_BUILDDIR.
#
# The traditional way of starting a subdir-configure is running the script
# with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
# to rely on eval'ing $ac_configure_args however some old autoconf
# versions do not provide that. To ensure maximum portability of autoconf
# extension macros this helper can be AC_REQUIRE'd so that
# $ac_configure_args will alsways be present.
#
# Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
# spoiled now and must be replaced by "eval + exit $?".
#
# Example:
#
# AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
# AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
# eval $SHELL $ac_configure_args || exit $?
# ...])

# SYNOPSIS
#
# AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
#
# DESCRIPTION
#
# If the current configure was run within the srcdir then we move all
# configure-files into a subdir and let the configure steps continue
# there. We provide an option --disable-builddir to suppress the move into
# a separate builddir.
#
# Defaults:
#
# $1 = $host (overridden with $HOST)
# $2 = Makefile.mk
# $3 = -all
#
# This macro must be called before AM_INIT_AUTOMAKE. It creates a default
# toplevel srcdir Makefile from the information found in the created
# toplevel builddir Makefile. It just copies the variables and
# rule-targets, each extended with a default rule-execution that recurses
# into the build directory of the current "HOST". You can override the
# auto-dection through `config.guess` and build-time of course, as in
#
# make HOST=i386-mingw-cross
#
# which can of course set at configure time as well using
#
# configure --host=i386-mingw-cross
#
# After the default has been created, additional rules can be appended
# that will not just recurse into the subdirectories and only ever exist
# in the srcdir toplevel makefile - these parts are read from the $2 =
# Makefile.mk file
#
# The automatic rules are usually scanning the toplevel Makefile for lines
# like '#### $host |$builddir' to recognize the place where to recurse
# into. Usually, the last one is the only one used. However, almost all
# targets have an additional "*-all" rule which makes the script to
# recurse into _all_ variants of the current HOST (!!) setting. The "-all"
# suffix can be overriden for the macro as well.
#
# a special rule is only given for things like "dist" that will copy the
# tarball from the builddir to the sourcedir (or $(PUB)) for reason of
# convenience.

# SYNOPSIS
#
# AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
#
# DESCRIPTION
#
# This macro tries to guess the "native" arch corresponding to the target
# architecture for use with gcc's -march=arch or -mtune=arch flags. If
# found, the cache variable $ax_cv_gcc_archflag is set to this flag and
# ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is set to
# "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
# to add $ax_cv_gcc_archflag to the end of $CFLAGS.
#
# PORTABLE? should be either [yes] (default) or [no]. In the former case,
# the flag is set to -mtune (or equivalent) so that the architecture is
# only used for tuning, but the instruction set used is still portable. In
# the latter case, the flag is set to -march (or equivalent) so that
# architecture-specific instructions are enabled.
#
# The user can specify --with-gcc-arch=<arch> in order to override the
# macro's choice of architecture, or --without-gcc-arch to disable this.
#
# When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
# called unless the user specified --with-gcc-arch manually.
#
# Requires macros: AX_CHECK_COMPILE_FLAG, AX_GCC_X86_CPUID
#
# (The main emphasis here is on recent CPUs, on the principle that doing
# high-performance computing on old hardware is uncommon.)

# SYNOPSIS
#
# AX_GCC_X86_CPUID(OP)
#
# 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.
#
# 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
# ax_cv_gcc_x86_cpuid_OP.
#
# If the cpuid instruction fails (because you are running a
# cross-compiler, or because you are not using gcc, or because you are on
# a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
# is set to the string "unknown".
#
# This macro mainly exists to be used in AX_GCC_ARCHFLAG.

/* ffi_call_SYSV()
Create a stack frame, setup an argument context, call the callee
and extract the result.
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
register context.
Prototype:
extern unsigned
ffi_call_SYSV (void (*)(struct call_context *context, unsigned char *,
extended_cif *),
struct call_context *context,
extended_cif *,
unsigned required_stack_size,
void (*fn)(void));

x1 &context
x2 &ecif
