5e88ebe627 arm: Remove internal FFI_TYPE constants 
These have been replaced by the contents of internal.h.

a4b785ea69 arm: Rewrite ffi_closure 
Move the push of the argument registers into ffi_closure_SYSV,
reducing the size of the trampoline.

e7f15f60e8 arm: Rewrite ffi_call 
Use the trick to allocate the stack frame for ffi_call_SYSV
within ffi_call itself.

a74a3aaddb arm: Rewrite vfp_type_p 
Do not modify the ffi_type.  Rearrange the tests so that we
quickly eliminate structures that cannot match.  Return an
encoded value of element count and base type.

5f917371af alpha: Clean up conversion of float values 
Don't use "real" conversion to double, lest we raise
exceptions when passing signalling nans.

32a26b75ba alpha: Reorganize cif flags 
Unties the backend from changes to FFI_TYPE_* constants, and allows
compilation to succeed after the addition of FFI_TYPE_COMPLEX.

Delete the hand-written unwind info.

0e41c73b09 aarch64: Move x8 out of call_context 
Reduces stack size.  It was only used by the closure, and there
are available argument registers.

658b2b5600 aarch64: Remove aarch64_flags 
This field was useless from the start, since the normal flags
field is available for backend use.

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.

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.

325471ea6a aarch64: Merge prep_args with ffi_call

within ffi_call itself.

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.

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

2e32f9bf6f aarch64: Use correct return registers 
There are fewer return registers than argument registers.

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.

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.

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.

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.

b21ec1ce78 x86: Rewrite closures 
Move everything into sysv.S, removing win32.S and freebsd.S.
Handle all abis with a single ffi_closure_inner function.
Move complexity of the raw THISCALL trampoline into assembly
instead of the trampoline itself.
Only push the context for the REGISTER abi; let the rest
receive it in a register.

b9ac94f3af x86: Rewrite ffi_call 
Decouple the assembly from FFI_TYPE_*.  Merge prep_args with ffi_call,
passing the frame and the stack to the assembly.

Note that this patch isn't really standalone, as this breaks closures.

e7b0056d60 x86: Force FFI_TYPE_LONGDOUBLE different from FFI_TYPE_DOUBLE 
There are few abis that set double = long double.  Eliminate the
conditional compilation and let this code simply be unused there.

4b2fad8fd5 x86: Remove some conditional compilation 
Removal of ifdefs made possible to due to ffi_abi unification.

ef76205647 x86: Tidy ffi_abi 
The x86_64 unix port only handles one ABI; don't define all of the
other symbols.  The UNIX64 symbol retains the same value.

The i386 ports ought to have the same symbols, even if we can't yet
unify the values without incrementing the libffi soname.

fc501750f4 testsuite: Fix return_complex2 vs excessive precision

recomputing a floating point result with excess precision.

99db4d42ac win64: Rewrite 
It's way too different from the 32-bit ABIs with which it is
currently associated. As seen from all of the existing XFAILs.

6b62fb4a26 x86-64: Support go closures 
Dumps all of the hand-coded unwind info for gas generated.  Move jump
table data into .rodata.  Adjust ffi_call_unix64 to load the static
chain.  Split out sse portions of ffi_closure_unix64 to
ffi_closure_unix64_sse rather than test cif->flags at runtime.

89bbde8b4e Add ffi_cfi.h

e951d64c08 Add entry points for interacting with Go 
A "ffi_go_closure" is intended to be compatible with the
function descriptors used by Go, and ffi_call_go sets up
the static chain parameter for calling a Go function.

The entry points are disabled when a backend has not been
updated, much like we do for "normal" closures.
