*  libffi: added ARM64 support for Windows

    1. ported sysv.S to win64_armasm.S for armasm64 assembler
    2. added msvc_build folder for visual studio solution
    3. updated README.md for the same
    4. MSVC solution created with the changes, and below test suites are tested
       with test script written in python.

       libffi.bhaible
       libffi.call
    5. Basic functionality of above test suites are getting passed

Florian Weimer 44a6c28545 aarch64: Flush code mapping in addition to data mapping (#471) 
This needs a new function, ffi_data_to_code_pointer, to translate
from data pointers to code pointers.

Fixes issue #470.

Andreas Schwab e66fd67820 Revert "Fix passing struct by value on aarch64" 
This reverts commit 482b37f004.

That was actually a bug in python, see <https://bugs.python.org/issue30353>.

Ole André Vadla Ravnås 4da814b18a aarch64: Fix handling of aggregates larger than 16 bytes 
Instead of allocating stack space for a pointer we would allocate stack
space for the actual aggregate size.

Yavor Georgiev 536366349c aarch64: implement the trampoline table workaround for ffi closures on Apple systems 
This is a direct copy/paste port of the ARM code, with changes because of Aarch64 pc-relative addressing restrictions.

Richard Henderson c6352b664c aarch64: Add support for Go closures 2014-11-12 09:29:32 +01:00
Richard Henderson 0e41c73b09 aarch64: Move x8 out of call_context 
Reduces stack size.  It was only used by the closure, and there
are available argument registers.
 2014-11-12 09:29:32 +01:00
Richard Henderson a992f8789b aarch64: Add support for complex types 2014-11-12 09:29:31 +01:00
Richard Henderson 658b2b5600 aarch64: Remove aarch64_flags 
This field was useless from the start, since the normal flags
field is available for backend use.

Richard Henderson 4a3cbcaa4f aarch64: Unify scalar fp and hfa handling 
Since an HFA of a single element is exactly the same as scalar,
this tidies things up a bit.

Richard Henderson 12cf89ee04 aarch64: Move return value handling into ffi_closure_SYSV 
As with the change to ffi_call_SYSV, this avoids copying data
into a temporary buffer.
 2014-11-12 09:28:44 +01:00
Richard Henderson 4fe1aea121 aarch64: Move return value handling into ffi_call_SYSV 
This lets us pass return data directly to the caller of ffi_call
in most cases, rather than storing it into temporary storage first.
 2014-11-12 09:28:44 +01:00
Richard Henderson 325471ea6a aarch64: Merge prep_args with ffi_call 
Use the trick to allocate the stack frame for ffi_call_SYSV
within ffi_call itself.

Richard Henderson 8c8161cb62 aarch64: Tidy up abi manipulation 
Avoid false abstraction, like get_x_addr.  Avoid recomputing data
about the type being manipulated.  Use NEON insns for HFA manipulation.

Note that some of the inline assembly will go away in a subsequent patch.

Richard Henderson b55e03665d aarch64: Treat void return as not passed in registers 
This lets us do less post-processing when there's no return value.

Richard Henderson 95a04af134 aarch64: Reduce the size of register_context 
We don't need to store 32 general and vector registers.
Only 8 of each are used for parameter passing.

Richard Henderson 77c4cddca6 aarch64: Simplify AARCH64_STACK_ALIGN 
The iOS abi doesn't require padding between arguments, but
that's not what AARCH64_STACK_ALIGN meant.  The hardware will
in fact trap if the SP register is not 16 byte aligned.

Richard Henderson b5f147d847 aarch64: Always distinguish LONGDOUBLE 
Avoid if-deffery by forcing FFI_TYPE_LONGDOUBLE different
from FFI_TYPE_DOUBLE.  This will simply be unused on hosts
that define them identically.
 2014-11-12 09:28:44 +01:00
Richard Henderson 38b54b9c18 aarch64: Improve is_hfa 
The set of functions get_homogeneous_type, element_count, and is_hfa
are all intertwined and recompute data.  Return a compound quantity
from is_hfa that contains all the data and avoids the recomputation.

Ole André Vadla Ravnås 0f4e09d27d Fix non-variadic CIF initialization for Apple/ARM64 
Turns out `aarch64_nfixedargs` wasn't initialized in the non-variadic
case, resulting in undefined behavior when allocating arguments.
