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.

Russell Keith-Magee bc4fc07aa5 Fixed #181 -- Corrected problems with ARMv7 build under iOS. 
Based on a patch from @fealebenpae, with input from @SolaWing and @rth7680,
and testing from @superdump.

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.

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.

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.
