Makefile: enable target overridings. (#661)
This patch allows target to provide extra files enabling the
override of Makefile rules.
This patch is not needed for libffi itself but only for GCC on AIX. The
t-aix file which is here empty will be replaced in GCC repository. We cannot
include GCC version directly here because it has no sense for a standalone
libffi.

Fix .cfi pseudo-ops test.
The existing tests were failing because the GCC was wrapping the test
asm in cfi directives, which gas doesn't like. So now we test if the
compiler emits them first, and assume that the assembler will accept
them. If that doesn't work, then we test if the assembler will accept
them assuming the compiler doesn't emit them.

configure.ac: use grep -E instead of egrep if possible (#720)
Upstream will start to emit a warning if egrep is invoked in the next
grep release. Stop invoking it explicitly. Use AC_PROG_EGREP to try
"grep -E" first, and fallback to egrep if "grep -E" does not work. We
need this fallback for some non-GNU grep implementations (like Solaris).

configure.ac: add --disable-exec-static-tramp flag (#647)
Some projects like GHC (Glasgow Haskell Compiler) and
gobject-introspection use `ffi_closure_alloc()` as a way
to allocate executable memory. exec static tramp
interferes with it (unclear how exactly yet).

configure.ac: allow user to specify READELF (#646)
Before the change with x86_64-pc-linux-gnu cross-compiler
installed the configure was not able to find cross-readelf:
```
$ ./configure --host=x86_64-pc-linux-gnu
...
checking whether .eh_frame section should be read-only... .././configure: line 19540: readelf: command not found
yes
...
```
The change uses AC_CHECK_TOOL to automatically seatch for ${host}-readelf,
readelf. And as a bonus it also allows user to override readelf with
something like READELF=llvm-readelf.

testsuite: fix compiler vendor detection on dash as /bin/sh (#594)
In https://bugs.gentoo.org/753299 Paolo Pedroni reported
a single test failure out of all libffi. Here is the minimal
reproducer:
```
$ ./autogen
$ CONFIG_SHELL=/bin/dash ./configure --host=x86_64-pc-linux-gnu
$ make check RUNTESTFLAGS='complex.exp'
...
FAIL: libffi.complex/cls_align_complex_float.c (test for excess errors)
```
This happens because under 'dash' shell autoconf generates slightly
different style of string quotation in `config.log`:
- on bash: `ax_cv_c_compiler_vendor=gnu`
- on dash: `ax_cv_c_compiler_vendor='gnu'`
To avoid shell quotation parsing the change just embeds
`compiler_vendor` into `local.exp` at configure time.

Static tramp v5 (#624)
* Static Trampolines
Closure Trampoline Security Issue
=================================
Currently, the trampoline code used in libffi is not statically defined in
a source file (except for MACH). The trampoline is either pre-defined
machine code in a data buffer. Or, it is generated at runtime. In order to
execute a trampoline, it needs to be placed in a page with executable
permissions.
Executable data pages are attack surfaces for attackers who may try to
inject their own code into the page and contrive to have it executed. The
security settings in a system may prevent various tricks used in user land
to write code into a page and to have it executed somehow. On such systems,
libffi trampolines would not be able to run.
Static Trampoline
=================
To solve this problem, the trampoline code needs to be defined statically
in a source file, compiled and placed in the text segment so it can be
mapped and executed naturally without any tricks. However, the trampoline
needs to be able to access the closure pointer at runtime.
PC-relative data referencing
============================
The solution implemented in this patch set uses PC-relative data references.
The trampoline is mapped in a code page. Adjacent to the code page, a data
page is mapped that contains the parameters of the trampoline:
- the closure pointer
- pointer to the ABI handler to jump to
The trampoline code uses an offset relative to its current PC to access its
data.
Some architectures support PC-relative data references in the ISA itself.
E.g., X64 supports RIP-relative references. For others, the PC has to
somehow be loaded into a general purpose register to do PC-relative data
referencing. To do this, we need to define a get_pc() kind of function and
call it to load the PC in a desired register.
There are two cases:
1. The call instruction pushes the return address on the stack.
In this case, get_pc() will extract the return address from the stack
and load it in the desired register and return.
2. The call instruction stores the return address in a designated register.
In this case, get_pc() will copy the return address to the desired
register and return.
Either way, the PC next to the call instruction is obtained.
Scratch register
================
In order to do its job, the trampoline code would need to use a scratch
register. Depending on the ABI, there may not be a register available for
scratch. This problem needs to be solved so that all ABIs will work.
The trampoline will save two values on the stack:
- the closure pointer
- the original value of the scratch register
This is what the stack will look like:
sp before trampoline ------> --------------------
| closure pointer |
--------------------
| scratch register |
sp after trampoline -------> --------------------
The ABI handler can do the following as needed by the ABI:
- the closure pointer can be loaded in a desired register
- the scratch register can be restored to its original value
- the stack pointer can be restored to its original value
(the value when the trampoline was invoked)
To do this, I have defined prolog code for each ABI handler. The legacy
trampoline jumps to the ABI handler directly. But the static trampoline
defined in this patch jumps tp the prolog code which performs the above
actions before jumping to the ABI handler.
Trampoline Table
================
In order to reduce the trampoline memory footprint, the trampoline code
would be defined as a code array in the text segment. This array would be
mapped into the address space of the caller. The mapping would, therefore,
contain a trampoline table.
Adjacent to the trampoline table mapping, there will be a data mapping that
contains a parameter table, one parameter block for each trampoline. The
parameter block will contain:
- a pointer to the closure
- a pointer to the ABI handler
The static trampoline code would finally look like this:
- Make space on the stack for the closure and the scratch register
by moving the stack pointer down
- Store the original value of the scratch register on the stack
- Using PC-relative reference, get the closure pointer
- Store the closure pointer on the stack
- Using PC-relative reference, get the ABI handler pointer
- Jump to the ABI handler
Mapping size
============
The size of the code mapping that contains the trampoline table needs to be
determined on a per architecture basis. If a particular architecture
supports multiple base page sizes, then the largest supported base page size
needs to be chosen. E.g., we choose 16K for ARM64.
Trampoline allocation and free
==============================
Static trampolines are allocated in ffi_closure_alloc() and freed in
ffi_closure_free().
Normally, applications use these functions. But there are some cases out
there where the user of libffi allocates and manages its own closure
memory. In such cases, static trampolines cannot be used. These will
fall back to using legacy trampolines. The user has to make sure that
the memory is executable.
ffi_closure structure
=====================
I did not want to make any changes to the size of the closure structure for
this feature to guarantee compatibility. But the opaque static trampoline
handle needs to be stored in the closure. I have defined it as follows:
- char tramp[FFI_TRAMPOLINE_SIZE];
+ union {
+ char tramp[FFI_TRAMPOLINE_SIZE];
+ void *ftramp;
+ };
If static trampolines are used, then tramp[] is not needed to store a
dynamic trampoline. That space can be reused to store the handle. Hence,
the union.
Architecture Support
====================
Support has been added for x64, i386, aarch64 and arm. Support for other
architectures can be added very easily in the future.
OS Support
==========
Support has been added for Linux. Support for other OSes can be added very
easily.

Support -ios triple
Autoconf hasn’t had an update since 2014, and it doesn’t look like it will soon[1]
This updates config.{guess,sub}
It adds support for e.g. `-ios`, which allows to have targets like `aarch64-apple-ios`.
It basically does exactly what the config.guess script says:
> It is advised that you download the most up to date version of the config scripts from
The configure.ac script has been updated to relax `*-apple-darwin*` to `*-apple-*`.
Similarly the `.gitignore` and `autogen.sh` needed to be updated to respect the
newer `config.{sub,guess}`

fix documentation building
An earlier patch added --disable-docs, but went too far, making it
impossible to build the docs.
It turns out that Automake seemingly has a bug preventing the
conditional build of an info file. So, this patch works around the
bug by putting the info_TEXINFOS rule into a new doc/Makefile.am.
Tested by building with and without --disable-docs and looking for the
existence of doc/libffi.info.

This is the only available configuration under Linux.
The description of the ABI can be found on the official website.
Is passes the testsuite except of the unwindtest_ffi_call.cc
testcase, which seems to be a problem of gcc and not libffi.
Some testcases of the gcc testsuite still fail.

Always use configure to detect whether global symbols need underscores
64-bit Windows already used this check; make it universal, and use it in
place of an ifdef on X86_WIN32, to handle non-Windows platforms that use
the underscore, such as Darwin.

This separates the 32-bit sysv/linux/bsd code from the 64-bit linux
code, and makes it possible to link code compiled with different
options to those used to compile libffi. For example, a
-mlong-double-128 libffi can be used with -mlong-double-64 code.
Using the return value area as a place to pass parameters wasn't such
a good idea, causing a failure of cls_ulonglong.c. I didn't see this
when running the mainline gcc libffi testsuite because that version of
the test is inferior to the upstreamm libffi test.
Using NUM_FPR_ARG_REGISTERS rather than NUM_FPR_ARG_REGISTERS64 meant
that a parameter save area could be allocated before it was strictly
necessary. Wrong but harmless. Found when splitting apart ffi.c
into 32-bit and 64-bit support.
