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.

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.

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.

Fix alignment of FFI_TYPE_FLOAT for Apple's ARM64 ABI

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.
