Martin Storsjö bd6ecbe48a libgcc: Expose the instruction pointer and stack pointer in SEH _Unwind_Backtrace
Previously, the SEH version of _Unwind_Backtrace did unwind
the stack and call the provided callback function as intended,
but there was little the caller could do within the callback to
actually get any info about that particular level in the unwind.

Set the ra and cfa pointers, which are used by _Unwind_GetIP
and _Unwind_GetCFA, to allow using these functions from the
callacb to inspect the state at each stack frame.

	* unwind-seh.c (_Unwind_Backtrace): Set the ra and cfa pointers
	before calling the callback.

Bernd Edlinger 54fde020cc Enable Java on Cygwin-64
Currently it is not possible to build GCC's libjava support on Cygwin-64.

This patch fixes the current build-problems on Cygwin-64 and the most
fundamental bugs on that platform.

Note you must still add --enable-threads=posix to successfully build the
java language support.


boehm-gc/ChangeLog:

2014-05-13  Bernd Edlinger  <bernd.edlinger@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.

        * 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.

libgcc/ChangeLog:

2014-05-13  Bernd Edlinger  <bernd.edlinger@hotmail.de>

        * unwind-seh.c (_Unwind_Backtrace): Uncommented, finished
        implementation.

libjava/ChangeLog:

2014-05-13  Bernd Edlinger  <bernd.edlinger@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.

libjava/classpath/ChangeLog:
