x86: Add indirect branch tracking support (#540)
Intel Control-flow Enforcement Technology (CET):
https://software.intel.com/en-us/articles/intel-sdm
contains shadow stack (SHSTK) and indirect branch tracking (IBT). When
CET is enabled, ELF object files must be marked with .note.gnu.property
section. When Intel CET is enabled, include <cet.h> in assembly codes
to mark Intel CET support.
Also when IBT is enabled, all indirect branch targets must start with
ENDBR instruction and notrack prefix can be used to disable IBT on
indirect branch. <cet.h> defines _CET_ENDBR which can be used in
assembly codes for ENDBR instruction. If <cet.h> isn't included,
define _CET_ENDBR as empty so that _CET_ENDBR can be used in assembly
codes.
Trampoline must be enlarged to add ENDBR instruction unconditionally,
which is NOP on non-CET processors. This is required regardless if
libffi is enabled with CET since libffi.so will be marked in legacy
bitmap, but trampoline won't. Update library version for larger
FFI_TRAMPOLINE_SIZE.
This fixed:
https://github.com/libffi/libffi/issues/474
Tested with
$ CC="gcc -Wl,-z,cet-report=error -fcf-protection" CXX="g++ -Wl,-z,cet-report=error -fcf-protection" .../configure
on Linux CET machines in i686, x32 and x86-64 modes.

powerpc: fix build failure on power7 and older (#532)
Build failure looks as:

ffi_[go_]closure_STDCALL doesn't adjust too much.

hppa: avoid TEXTREL in .eh_frame section (#447)
Before the change hand-crafted .eh_frame section contained
ABS relocation and caused TEXTREL tag to be emitted:
```
$ ./configure --host=hppa2.0-unknown-linux-gnu LDFLAGS=-Wl,-z,text
$ make
...
/usr/libexec/gcc/hppa2.0-unknown-linux-gnu/ld:
read-only segment has dynamic relocations.
```
Link failure is caused by absolute address of FDEs
encoded into .eh_frame entries.
Fixed TEXTREL by using pcrel (instead of ABS) encoding
for absolute addresses (__PIC__ code) by adding augmentation
information ("zR" CIE type).
All tests still pass on hppa2.0. The specific tests that still pass
and exercise this code path:

PowerPC64 ELFv1 fp arg fixes
The ELFv1 ABI says: "Single precision floating point values are mapped
to the second word in a single doubleword" and also "Floating point
registers f1 through f13 are used consecutively to pass up to 13
floating point values, one member aggregates passed by value
containing a floating point value, and to pass complex floating point
values".
libffi wasn't expecting float args in the second word, and wasn't
passing one member aggregates in fp registers. This patch fixes those
problems, making use of the existing ELFv2 homogeneous aggregate
support since a one element fp struct is a special case of an
homogeneous aggregate.
I've also set a flag when returning pointers that might be used one
day. This is just a tidy since the ppc64 assembly support code
currently doesn't test FLAG_RETURNS_64BITS for integer types..
* src/powerpc/ffi_linux64.c (discover_homogeneous_aggregate):
Compile for ELFv1 too, handling single element aggregates.
(ffi_prep_cif_linux64_core): Call discover_homogeneous_aggregate
for ELFv1. Set FLAG_RETURNS_64BITS for FFI_TYPE_POINTER return.
(ffi_prep_args64): Call discover_homogeneous_aggregate for ELFv1,
and handle single element structs containing float or double
as if the element wasn't wrapped in a struct. Store floats in
second word of doubleword slot when big-endian.
(ffi_closure_helper_LINUX64): Similarly.

Fix two "return" issues in x86/ffi64.c (#431)
Issue #70 pointed out that at least one compiler didn't like:
return ffi_call_efi64(cif, fn, rvalue, avalue);
... where the return type is "void". This patch splits the statement
into two.
I also noticed that ffi_call_go here seems to do a double call. I
suspect a "return" is missing here, so this patch adds it as well.

Various MIPS Fixes (#425)
* mips: simplify closure #defines
This commit should have no visible effect.
* mips: add special handling of variadic functions
MIPS requires special handling of variadic functions which pass floating
point arguments:
* In the o32 ABI, all float arguments are passed in integer registers.
* In the n32/n64 ABIs, float arguments after the ellipsis are passed in
integer registers.
Implement this in libffi. To support this in n32/n64 closures, we need to add
a new mips_nfixedargs field to ffi_cif which will break the libffi ABI.
This fixes the libffi.call/cls_longdouble_va.c test which was failing on
64-bit MIPS.
* mips: align argn for all 64-bit types in o32 closure handler
Ensure that argn is pre-aligned for all 64-bit argument types (including
doubles) and not just integer types.
This fixes closures of the form "f(float, double, <some integer args>)".
Previously the first integer argument would be read from a2 which is garbage
at this point (the float arguments have already "consumed" a0-a3). After
this commit, argn is correctly padded between the "float" and "double"
arguments so that the first integer argument is read from the stack.
Fixes "double f(float,double,int)" test in #371
* mips: do not read from floating point register if returning a struct
In the o32 ABI, the pointer passed in a0 used to return structures
indirectly is treated as the first argument for argument allocation purposes.
This means that it should inhibit floating point registers the same way that
other integer arguments do.
Fixes "Double f(float,Double,double)" test in #371
* mips: fix pointer cast warnings
Fix two pointer cast warnings when compiled on 64-bit mips by casting
through uintptr_t.
Fixes mips64el part of #404

ia64: fix small struct return
This change fixes libffi.call/struct10.c failure on ia64:
FAIL: libffi.call/struct10.c -W -Wall -Wno-psabi -O0 execution test
.Lst_small_struct handles returns for structs less than 32 bytes
(following ia64 return value ABI [1]). Subroutine does roughly the
following:
```
mov [sp+0] = r8
mov [sp+8] = r9
mov [sp+16] = r10
mov [sp+24] = r11
memcpy(destination, source=sp, 12);
```
The problem: ia64 ABI guarantees that top 16 bytes of stack are
scratch space for callee function. Thus it can clobber it. [1]
says (7.1 Procedure Frames):
"""
* Scratch area. This 16-byte region is provided as scratch storage
for procedures that are called by the current procedure. Leaf
procedures do not need to allocate this region. A procedure may
use the 16 bytes at the top of its own frame as scratch memory,
but the contents of this area are not preserved by a procedure call.
"""
In our case 16 top bytes are clobbered by a PLT resolver when memcpy()
is called for the first time. As a result memcpy implementation reads
already clobbered data frop top of stack.
The fix is simple: allocate 16 bytes of scrats space prior to memcpy()
call.

```
libffi expects 'doubleArg' to be located in 'f9' (second FP argument) but
gcc placed it to 'r33' (second GR).
ia64 software [1] manual described argument passing ABI in
"8.5.2 Register Parameters" as:
"""
If an actual parameter is known to correspond to a floating-point
formal parameter, the following rules apply:
a) The actual parameter is passed in the next available floating-point
parameter register, if one is available. Floating-point parameter
registers are allocated as needed from the range f8-f15, starting
with f8.
b) If all available floating-point parameter registers have been used,
the actual parameter is passed in the appropriate general register(s).
(This case can occur only as a result of homogeneous floating-point
aggregates, described below.)
If a floating-point actual parameter is known to correspond to
a variable-argument specification in the formal parameter list,
the following rule applies:
c) The actual parameter is passed in the appropriate general
register(s).
If the compiler cannot determine, at the point of call,
whether the corresponding formal parameter is a varargs parameter,
it must generate code that satisfies both of the above conditions.
(The compiler’s determination may be based on prototype declarations,
language standard assumptions, analysis, or other user options or
information.)
"""
We have [c] case here and gcc uses only GR for parameter passing.
The change binds known variadic arguments ro GRs instead of FPs as those
are always expected to be initialized for all variadic call types.
This fixes all 10 failures on ia64-unknown-linux-gnu:

arm: fix a level of indirection issue
Rather than relying on the stack being 0'ed out always, do it manually.
The stack generally happened to be zero, and because the compiler
realizes that the tests are dealing with chars truncates the read value.
However, the top 3 nibbles of the value are undefined and may be
non-zero. The indirection level caused a null-pointer dereference.
Explicitly scribbling on the stack during the allocation causes test
failures without the original zexting behaviour.

src/ia64/unix.S: unbreak small struct handling
commit 6e8a4460833594d5af1b4539178025da0077df19
added FFI_TYPE_COMPLEX value type (comes after FFI_TYPE_POINTER)
ia64 ffi_closure_unix reiles on the ordering of
FFI_ enums as ia64 has ia64-specific FFI types:
small struct and FPU extesions.
As a result all tests handling small structs broke.
The change fixes dispatch table by adding (no-op)
FFI_TYPE_COMPLEX entry
This has positive effect of unbreaking most tests
on ia64:

arm: zext return value parameters
The closure function (invoked as closure->fun in ffi_closure_XXX_inner)
will only populate the actual number of bytes for the true return type,
which may be a character. This leaves garbage on the stack when the
assembly closure function (i.e. ffi_closure_XXX) reads the return value
off of the stack into r0 as a 4-byte value. ffi_closure_XXX always
leaves room for at least 4 bytes here, so we can safely set them to 0.
Otherwise, if there is garbage in any of these bytes, these end up in r0
and in the returned value as well.
