fa1040c1	2014-11-10T09:42:31	GO closures for powerpc linux Plus .cfi async unwind info, rearrangement of ffi_call_linux64 and ffi_call_SYSV function params to avoid register copies, tweaks to trampolines. * src/powerpc/ffitarget.h (FFI_GO_CLOSURES): Define. * src/powerpc/ffi.c (ffi_call_int): New function with extra closure param, and args rearranged on ffi_call_linux64 and ffi_call_SYSV calls, extracted from .. (ffi_call): ..here. (ffi_call_go, ffi_prep_go_closure): New functions. * src/powerpc/ffi_linux64.c (ffi_prep_closure_loc_linux64): Make hidden. Only flush insn part of ELFv2 trampoline. Don't shuffle ELFv1 trampoline. (ffi_closure_helper_LINUX64): Replace closure param with cif, fun, user_data params. * src/powerpc/ffi_powerpc.h (ffi_go_closure_sysv): Declare. (ffi_go_closure_linux64): Declare. (ffi_call_SYSV, fi_call_LINUX64): Update. (ffi_prep_closure_loc_sysv, ffi_prep_closure_loc_linux64): Declare. (ffi_closure_helper_SYSV, ffi_closure_helper_LINUX64): Update. * src/powerpc/ffi_sysv.c (ASM_NEEDS_REGISTERS): Increase to 6. (ffi_prep_closure_loc_sysv): Use bcl in trampoline, put data words last, flush just the insn part. (ffi_closure_helper_SYSV): Replace closure param with cif, fun and user_data params. * src/powerpc/linux64.S (ffi_call_LINUX64): Replace hand-written .eh_frame with .cfi directives. Adjust for changed param order. Pass extra "closure" param to user function in static chain. Add .cfi directives to describe epilogue. Don't provide traceback table for ELFv2 or _CALL_LINUX. * src/powerpc/linux64_closure.S (ffi_closure_LINUX64): Replace hand-written .eh_frame with .cfi directives. Adjust for changed ffi_closure_helper_LINUX64 params. Add .cfi directives to describe epilogue. Don't provide traceback table for ELFv2 or _CALL_LINUX. (ffi_go_closure_linux64): New function. * src/powerpc/sysv.S: Remove redundant .globl ffi_prep_args_SYSV. (ffi_call_SYSV): Make hidden. Replace hand-written .eh_frame with .cfi directives. Adjust for changed params. Pass extra "closure" param to user function in static chain. Add .cfi directives to describe epilogue. * src/powerpc/ppc_closure.S (ffi_closure_SYSV): Make hidden. Replace hand-written .eh_frame with .cfi directives. Adjust for changed ffi_closure_helper_SYSV params. Add .cfi directives to describe epilogue. Don't just use nops in the dead __NO_FPRS__ epilogues. (ffi_go_closure_sysv): New function.
ab79d6e2	2013-11-21T06:12:35	This separates the 32-bit sysv/linux/bsd code from the 64-bit linux code, and makes it possible to link code compiled with different options to those used to compile libffi. For example, a -mlong-double-128 libffi can be used with -mlong-double-64 code. Using the return value area as a place to pass parameters wasn't such a good idea, causing a failure of cls_ulonglong.c. I didn't see this when running the mainline gcc libffi testsuite because that version of the test is inferior to the upstreamm libffi test. Using NUM_FPR_ARG_REGISTERS rather than NUM_FPR_ARG_REGISTERS64 meant that a parameter save area could be allocated before it was strictly necessary. Wrong but harmless. Found when splitting apart ffi.c into 32-bit and 64-bit support.

36285137	2013-11-16T06:52:43	Andreas' 2013-02-08 change reverted some breakage for struct return values from 2011-11-12, but in so doing reintroduced string instructions to sysv.S that are not supported on all powerpc variants. This patch properly copies the bounce buffer to destination in C code rather than in asm. I have tested this on powerpc64-linux, powerpc-linux and powerpc-freebsd. Well, the last on powerpc-linux by lying to configure with CC="gcc -m32 -msvr4-struct-return -mlong-double-64" \ CXX="g++ -m32 -msvr4-struct-return -mlong-double-64" \ /src/libffi-current/configure --build=powerpc-freebsd and then make && make CC="gcc -m32" CXX="g++ -m32" \ RUNTESTFLAGS=--target_board=unix/-m32/-msvr4-struct-return/-mlong-double-64\ check
