Richard Henderson dea49e20 2014-11-14T13:05:14 x86: Fix typo in ffi_prep_go_closure Used the wrong register for THISCALL and FASTCALL.
Richard Henderson c9f5b664 2014-11-14T13:04:33 testsuite: Add trivial tests for Go closures
Richard Henderson c952a92e 2014-11-14T11:00:14 testsuite: Move complex tests to their own subdirectory It seems a bit silly to isolate them by globbing vs "*complex*" when we can just as easily put them in their own subdirectory.
Richard Henderson f1301a54 2014-11-14T10:50:29 testsuite: Use feature test rather than enumeration for complex
Richard Henderson b5ade2fb 2014-11-13T09:06:10 testsuite: Detect clang Clang doesn't like the -Wno-psabi argument that we want to pass to GCC. Since clang is detected as GCC via __GNUC__, use ax_cv_c_compiler_vendor.
Richard Henderson 5d69d57a 2014-11-13T13:50:39 configure: Move target source selection into configure.host This eliminates the AM_CONDITIONAL ugliness, which eliminates just a bit of extra boilerplate for a new target. At the same time, properly categorize the EXTRA_DIST files into SOURCES and HEADERS, for the generation of ctags.
Anatoly Trosinenko 771fabc6 2014-11-14T14:21:35 Take a float absolute value using fabs() instead of abs(). Replace integer abs() by floating point fabs() in the approximate equality check for float values.
Anatoly Trosinenko 9622ede2 2014-11-14T13:18:04 Fix floating point number comparisons in testsuite/libffi.call/float[123].c. Rewrite the checks for approximate equality of floating point return values to be in the form "fabs(a - b) < EPS" instead of just "a - b < EPS".
Adam e029c70f 2014-11-13T15:08:16 Update i386 & armv7 minimum iOS version to 7.0 iOS 5 (and any below 7.1) is deprecated. Apple doesn't distribute the supporting libraries for this platform anymore as of Xcode 6, so it causes a linker error.
Richard Henderson 57f52484 2014-11-13T12:42:54 configure: Split out configure.host Split out the host case statement to a separate file, so that we don't have to regenerate configure.in for changes therein.
Richard Henderson f8632815 2014-11-13T12:32:35 powerpc: Delete patch output Clearly added by mistake.

Anthony Green 20562ac0 2014-11-12T07:00:59 Fix for AArch64. Release as 3.2.1.
Richard Henderson 0e303c06 2014-11-12T03:58:58 x86: Work around clang bugs http://llvm.org/bugs/show_bug.cgi?21500 http://llvm.org/bugs/show_bug.cgi?21501 http://llvm.org/bugs/show_bug.cgi?21515
Richard Henderson 6eec410f 2014-10-26T15:29:04 sparc: Re-add abi compliant structure support The original code, removed in the "rewrite" patch, was incorrect for large structures, and required dynamic allocation of a trampoline on every ffi_call. Instead, allocate a 4k entry table of all possible structure returns. The table is 80k, but is read-only and dynamically paged, which ought to be better than allocating the trampoline. This is difficult to test with gcc. One can only use -O0 at present. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63668.

Richard Henderson 20da5b41 2014-10-25T16:24:41 sparc: Handle more cases of structure return directly
Richard Henderson 0686c2e7 2014-10-25T14:52:45 sparc: Preprocess float point struct return We can eliminate recursion and speed structure return by flattening a nested structure tree into a bitmask.
Richard Henderson 2b27890b 2014-10-24T16:10:48 sparc: Rewrite everything It's impossible to call between v8 and v9 ABIs, because of the stack bias in the v9 ABI. So let's not pretend it's just not implemented yet. Split the v9 code out to a separate file. The register windows prevent ffi_call from setting up the entire stack frame the assembly, but we needn't make an indirect call back to prep_args.
Richard Henderson 5d7b5445 2014-10-24T11:45:53 sparc: Tidy up symbols Assembly to use local labels, .type annotation, hidden annotation. I do retain the _prefix for the symbols, but given that it wasn't done consistently across all symbols, I doubt it's actually needed.
Richard Henderson fd4f7cc0 2014-10-24T11:11:53 sparc: Eliminate long double ifdefs
Richard Henderson ab83cbb9 2014-10-29T14:38:42 arm: Add support for Go closures
Richard Henderson 6fa617da 2014-10-21T11:27:11 arm: Add argument space for the hidden struct return pointer This should have been failing all along, but it's only exposed by the complex_int test case.
Richard Henderson a529bec2 2014-10-21T11:26:59 arm: Add support for complex types
Richard Henderson 5e88ebe6 2014-10-20T15:10:43 arm: Remove internal FFI_TYPE constants These have been replaced by the contents of internal.h.
Richard Henderson a4b785ea 2014-10-17T02:07:32 arm: Rewrite ffi_closure Move the push of the argument registers into ffi_closure_SYSV, reducing the size of the trampoline.
Richard Henderson e7f15f60 2014-10-17T01:27:16 arm: Rewrite ffi_call Use the trick to allocate the stack frame for ffi_call_SYSV within ffi_call itself.
Richard Henderson a74a3aad 2014-10-17T01:21:22 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.
Richard Henderson 0d39b4bb 2014-10-17T01:02:52 arm: Deref ffi_put_arg arguments

Richard Henderson 5f917371 2014-10-17T13:47:26 alpha: Clean up conversion of float values Don't use "real" conversion to double, lest we raise exceptions when passing signalling nans.
Richard Henderson 32a26b75 2014-10-17T12:33:53 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.
Richard Henderson c6352b66 2014-10-23T00:26:14 aarch64: Add support for Go closures
Richard Henderson 0e41c73b 2014-10-22T23:48:12 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 a992f878 2014-10-22T22:58:09 aarch64: Add support for complex types
Richard Henderson 658b2b56 2014-10-22T22:36:07 aarch64: Remove aarch64_flags This field was useless from the start, since the normal flags field is available for backend use.
Richard Henderson 4a3cbcaa 2014-10-22T22:32:13 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 12cf89ee 2014-10-22T21:53:30 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 4fe1aea1 2014-10-22T17:06:19 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 325471ea 2014-10-22T13:58:59 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 8c8161cb 2014-10-22T12:52:07 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 b55e0366 2014-10-22T12:33:59 aarch64: Treat void return as not passed in registers This lets us do less post-processing when there's no return value.
Richard Henderson 2e32f9bf 2014-10-21T22:49:05 aarch64: Use correct return registers There are fewer return registers than argument registers.
Richard Henderson 95a04af1 2014-10-21T22:41:07 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 77c4cddc 2014-10-21T13:30:40 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 b5f147d8 2014-10-21T13:27:57 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 38b54b9c 2014-10-21T13:17:39 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.
Richard Henderson 18b74ce5 2014-10-21T13:00:34 aarch64: Fix non-apple compilation
Richard Henderson 2650f47f 2014-11-06T10:57:04 x86: Use win32 name mangling for fastcall functions
Richard Henderson f8c64e24 2014-11-05T17:04:29 x86: Add support for Go closures
Richard Henderson 198f469e 2014-11-05T16:34:41 x86: Add support for Complex
Richard Henderson b21ec1ce 2014-11-05T10:15:25 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.
Richard Henderson 159d3788 2014-10-31T12:07:02 x86: Convert to gas generated unwind info
Richard Henderson e7b0056d 2014-10-30T13:57:39 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.
Richard Henderson 4b2fad8f 2014-10-30T12:41:31 x86: Remove some conditional compilation Removal of ifdefs made possible to due to ffi_abi unification.
Richard Henderson ef762056 2014-10-30T12:13:31 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.
Richard Henderson 7cf84132 2014-11-07T06:56:55 testsuite: Add two dg-do run markers Caught by clang warning about unused -L parameter.
Richard Henderson fc501750 2014-11-05T16:33:44 testsuite: Fix return_complex2 vs excessive precision Use the previously computed rc2 to validate, rather than recomputing a floating point result with excess precision.
Richard Henderson 610c90bf 2014-10-28T11:21:50 x86_64: Add support for complex types
Richard Henderson 32c56831 2014-10-28T11:17:35 x86_64: Decouple return types from FFI_TYPE constants We can better support structure returns, and as prep for complex types.
Richard Henderson 2e9dc165 2014-10-27T13:41:39 x86_64: Fixups for x32
Richard Henderson ebd82769 2014-10-23T23:57:06 win64: Remove support from ffi.c
Richard Henderson 99db4d42 2014-10-23T14:12:18 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.
Richard Henderson 6b62fb4a 2014-10-17T11:11:58 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.
Richard Henderson 89bbde8b 2014-10-17T10:55:11 Add ffi_cfi.h Have one copy of the HAVE_AS_CFI_PSEUDO_OP code to share between all backends.
Richard Henderson e951d64c 2014-10-17T10:12:25 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.
Richard Henderson b9ac94f3 2014-11-01T15:10:34 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.

Sebastian Macke 0f316ab7 2014-09-27T00:19:15 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. Signed-off-by: Sebastian Macke <sebastian@macke.de>
