Richard Henderson 18b74ce54a aarch64: Fix non-apple compilation 2014-11-12 09:28:44 +01:00
Richard Henderson 2650f47fe8 x86: Use win32 name mangling for fastcall functions 2014-11-12 09:16:02 +01:00
Richard Henderson f8c64e2486 x86: Add support for Go closures 2014-11-12 09:16:02 +01:00
Richard Henderson 198f469e91 x86: Add support for Complex 2014-11-12 09:16:02 +01:00
Richard Henderson 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.
 2014-11-12 09:15:54 +01:00
Richard Henderson 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.

Richard Henderson 159d3788eb x86: Convert to gas generated unwind info 2014-11-12 09:15:35 +01:00
Richard Henderson 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.
 2014-11-12 09:15:35 +01:00
Richard Henderson 4b2fad8fd5 x86: Remove some conditional compilation 
Removal of ifdefs made possible to due to ffi_abi unification.
 2014-11-12 09:15:35 +01:00
Richard Henderson 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.
 2014-11-12 09:15:35 +01:00
Richard Henderson 7cf841324f testsuite: Add two dg-do run markers 
Caught by clang warning about unused -L parameter.
 2014-11-12 09:15:35 +01:00
Richard Henderson fc501750f4 testsuite: Fix return_complex2 vs excessive precision 
Use the previously computed rc2 to validate, rather than
recomputing a floating point result with excess precision.
 2014-11-12 09:15:35 +01:00
Richard Henderson 610c90bf71 x86_64: Add support for complex types 2014-11-12 09:15:35 +01:00
Richard Henderson 32c5683163 x86_64: Decouple return types from FFI_TYPE constants 
We can better support structure returns, and as prep for
complex types.
 2014-11-12 09:15:35 +01:00
Richard Henderson 2e9dc16556 x86_64: Fixups for x32 2014-11-12 09:15:35 +01:00
Richard Henderson ebd82769de win64: Remove support from ffi.c 2014-11-12 09:15:35 +01:00
Richard Henderson 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.
 2014-11-12 09:15:35 +01:00
Richard Henderson 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.
 2014-11-12 09:15:35 +01:00
Richard Henderson 89bbde8b4e Add ffi_cfi.h 
Have one copy of the HAVE_AS_CFI_PSEUDO_OP code
to share between all backends.
 2014-11-12 09:15:35 +01:00
Richard Henderson 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.

Sebastian Macke 0f316ab7c1 Add OpenRISC support 
This patch adds support for the OpenRISC architecture.
(http://opencores.org/or1k/Main_Page)

This patch has been tested under Linux with QEMU-user emulation support.
- 32 Bit
- big endian
- delayed instructions
This is the only available configuration under Linux.

The description of the ABI can be found on the official website.

Is passes the testsuite except of the unwindtest_ffi_call.cc
testcase, which seems to be a problem of gcc and not libffi.
Some testcases of the gcc testsuite still fail.
