2023-05-06libffi: fix handling of homogeneous float128 structs (#689)Dan Horák1-1/+1
If there is a homogeneous struct with float128 members, they should be copied to vector register save area. The current code incorrectly copies only the value of the first member, not increasing the pointer with each iteration. Fix this.

2023-01-07Always define `WIN32_LEAN_AND_MEAN` before <windows.h>LIU Hao1-0/+1
Recently, mingw-w64 has got updated <msxml.h> from Wine which is included indirectly by <windows.h> if `WIN32_LEAN_AND_MEAN` is not defined. The `IXMLDOMDocument` class has a member function named `abort()`, which gets affected by our `abort()` macro in "system.h". `WIN32_LEAN_AND_MEAN` should, nevertheless, always be defined. This can exclude 'APIs such as Cryptography, DDE, RPC, Shell, and Windows Sockets' [1], and speed up compilation of these files a bit.

2022-12-21libffi: Fix X86 32b Darwin build and EH frames.Iain Sandoe1-38/+83
This addresses a number of issues in the X86 Darwin 32b port for libffi. 1. The pic symbol stubs are weak definitions; the correct section placement for these depends on the linker version in use. We do not have access to that information, but we can use the target OS version (assumes that the user has installed the latest version of xcode available). When a coalesced section is in use (OS versions earlier than Darwin12 / OSX 10.8), its name must differ from __TEXT,__text since otherwise that would correspond to altering the attributes of the .text section (which produces a diagnostic from the assembler). Here we use __TEXT, __textcoal_nt for this which is what GCC emits for these stubs. For later versions than Darwin 12 (OS X 10.8) we can place the stubs in the .text section (if we do not we get a diagnostic from clang -cc1as saying that the use of coalesced sections for this is deprecated). 2. The EH frame is specified manually, since there is no support for .cfi_ directives in 'cctools' assemblers. The implementation needs to provide offsets for CFA advance, code size and to the CIE as signed values rather than relocations. However the cctools assembler will produce a relocation for expressions like ' .long Lxx-Lyy' which then leads to a link-time error. We correct this by forming the offset values using ' .set' directives and then assigning the results of them. 3. The register numbering used by m32 X86 Darwin EH frames is not the same as the DWARF debug numbering (the Frame and Stack pointer numbers are swapped). 4. The FDE address encoding used by the system tools is '0x10' (PCrel + abs) where the value provided was PCrel + sdata4. 5. GCC does not use compact unwind at present, and it was not implemented until Darwin10 / OSX 10.6. There were some issues with function location in 10.6 so that the solution here suppresses emitting the compact unwind section until Darwin11 / OSX 10.7. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> libffi/ChangeLog: * src/x86/sysv.S (COMDAT): Amend section use for Darwin, accounting cases where coalesced is needed. (eh_frame): Rework to avoid relocs that cause builf fails on earlier Darwin. Adjust register numbers to account for X86 m32 Darwin differences between EH and debug.

2020-09-24[RS6000] Power10 libffi fixesAlan Modra2-1/+19
Power10 pc-relative code doesn't use or preserve r2 as a TOC pointer. That means calling between pc-relative and TOC using code can't be done without intervening linker stubs, and a call from TOC code to pc-relative code must have a nop after the bl in order to restore r2. Now the PowerPC libffi assembly code doesn't use r2 except for the implicit use when making calls back to C, ffi_closure_helper_LINUX64 and ffi_prep_args64. So changing the assembly to interoperate with pc-relative code without stubs is easily done. * src/powerpc/linux64.S (ffi_call_LINUX64): Don't emit global entry when __PCREL__. Call using @notoc. Add nops. * src/powerpc/linux64_closure.S (ffi_closure_LINUX64): Likewise. (ffi_go_closure_linux64): Likewise.

2018-05-04libffi PowerPC64 ELFv1 fp arg fixesAlan Modra1-16/+45
The ELFv1 ABI says: "Single precision floating point values are mapped to the second word in a single doubleword" and also "Floating point registers f1 through f13 are used consecutively to pass up to 13 floating point values, one member aggregates passed by value containing a floating point value, and to pass complex floating point values". libffi wasn't expecting float args in the second word, and wasn't passing one member aggregates in fp registers. This patch fixes those problems, making use of the existing ELFv2 homogeneous aggregate support since a one element fp struct is a special case of an homogeneous aggregate. I've also set a flag when returning pointers that might be used one day. This is just a tidy since the ppc64 assembly support code currently doesn't test FLAG_RETURNS_64BITS for integer types.. * src/powerpc/ffi_linux64.c (discover_homogeneous_aggregate): Compile for ELFv1 too, handling single element aggregates.

2015-10-01[RS6000] Correct powerpc sysv stack argument accountingAlan Modra1-109/+98
ppc32 starts using the stack for integer arg passing when we run out of integer arg passing registers. Similarly, we start using the stack for floating point args when we run out of floating point registers. The decision on where an integer arg goes does not depend on number of floating point args, nor does the decision on where a floating point arg goes depend on number of integer args. Alignment of stack args also simply depends on number of stack args. This patch untangles the horrible mess we had, with intarg_count being wrongly used to count both integer args and stack words. * src/powerpc/ffi_sysv.c (ffi_prep_cif_sysv_core): Count fprs, gprs, and stack words separately.
