Hi, I have the following comment.
boehm-gc/ChangeLog: 2014-05-11 Bernd Edlinger <bernd.edlin...@hotmail.de> Fix current cygwin-64 build problems. * include/gc_config_macros.h (GC_PTHREADS): Use __CYGWIN__ instead of __CYGWIN32__ here. * win32_threads.c (GC_push_all_stacks): Push all X86_64 registers. (GC_get_thread_stack_base): Get the stack base for X86_64. That change is ok. Please don't miss to post the changes also to boehm-gc's ML. In general it is better to splitt patches into seprate patches. To put all in one isn't ease review here. libffi/ChangeLog: 2014-05-11 Bernd Edlinger <bernd.edlin...@hotmail.de> Fix current cygwin-64 build problems. * src/java_raw_api.c: Remove if !defined(FFI_NO_RAW_API). * src/x86/ffi.c: Add if defined(__CYGWIN__). * src/x86/win64.S (ffi_closure_win64, ffi_call_win64): Added handling for FFI_TYPE_UINT64, FFI_TYPE_POINTER and FFI_TYPE_INT. Added SEH information. Fixed formatting. Patch is ok IMO. Nevertheless this part shall go also to libffi's ML. libgcc/ChangeLog: 2014-05-11 Bernd Edlinger <bernd.edlin...@hotmail.de> * unwind-seh.c (_Unwind_Backtrace): Uncommented, finished implementation. This part of the patch is ok. Please apply to trunk. libjava/ChangeLog: 2014-05-11 Bernd Edlinger <bernd.edlin...@hotmail.de> Fix current cygwin-64 build problems. * configure.host: Added handling for x86_64-*-cygwin/mingw. * boehm.cc (_Jv_GCAttachThread, _Jv_GCDetachThread): Don't compile if GC_WIN32_THREADS is defined. * java/lang/natClass.cc (_Jv_InterfaceAssignableFrom): Rename interface to source_interface. This part of the patch looks ok too. As here a libjava-maintainer needs to look into too, you should post this part again to ML with prominent marking libjava in subject line. libjava/classpath/ChangeLog: 2014-05-11 Bernd Edlinger <bernd.edlin...@hotmail.de> Fix current cygwin-64 build problems. * native/fdlibm/mprec.c (_REENT_CHECK_MP, _REENT_MP_FREELIST, _REENT_MP_P5S, __ULong, __Long): Undefine previous definitions. Same here. Looks ok to me, too. Nevertheless please post it as separate thread to ML. Thanks, Kai
