+/* This file declares various DWARF-related constants using a set of
+ macros which can be redefined by the including file.
+
+ The macros are in sections. Each section corresponds to a single
+ set of DWARF constants and has a corresponding key. The key is
+ used in all the macro names.
+
+ The sections are TAG (for DW_TAG_ constants), FORM (DW_FORM_), AT
+ (DW_AT_), OP (DW_OP_), ATE (DW_ATE_), and CFA (DW_CFA_).
+
+ Using TAG as an example, the following macros may be used for each
+ key:
+
+ DW_FIRST_TAG(name, value) - Introduce the first DW_TAG constant.
+
+ DW_TAG(name, value) - Define a subsequent constant.
+
+ DW_TAG_DUP(name, value) - Define a subsequent constant whose value
+ is a duplicate of some other constant. Not all keys use the _DUP
+ macro form. If more than one name shares a value, then the base
+ (DW_TAG) form will be the preferred name and DW_TAG_DUP will hold
+ any alternate names.
+
+ DW_END_TAG - Invoked at the end of the DW_TAG constants. */

+/* This file implements the md_fallback_frame_state_for routine for
+ Windows, triggered when the GCC table based unwinding process hits a
+ frame for which no unwind info has been registered. This typically
+ occurs when raising an exception from a signal handler, because the
+ handler is actually called from the OS kernel.
+
+ The basic idea is to detect that we are indeed trying to unwind past a
+ signal handler and to fill out the GCC internal unwinding structures for
+ the OS kernel frame as if it had been directly called from the
+ interrupted context.
+
+ This is all assuming that the code to set the handler asked the kernel
+ to pass a pointer to such context information.
+
+ There is three main parts.
+
+ 1) The first thing to do is to check if we are in a signal context. If
+ not we can just return as there is nothing to do. We are probably on
+ some foreign code for which no unwind frame can be found. If this is
+ a call from the Windows signal handler, then:
+
+ 2) We must get the signal context information.
+
+ * With the standard exception filter:
+
+ This is on Windows pointed to by an EXCEPTION_POINTERS. We know that
+ the signal handle will call an UnhandledExceptionFilter with this
+ parameter. The spec for this routine is:
+
+ LONG WINAPI UnhandledExceptionFilter(struct _EXCEPTION_POINTERS*);
+
+ So the pointer to struct _EXCEPTION_POINTERS must be somewhere on the
+ stack.
+
+ This was found experimentally to always be at offset 0 of the context
+ frame in all cases handled by this implementation.
+
+ * With the SEH exception handler:
+
+ In this case the signal context is directly on the stack as the SEH
+ exception handler has the following prototype:
+
+ DWORD
+ SEH_error_handler (PEXCEPTION_RECORD ExceptionRecord,
+ PVOID EstablisherFrame,
+ PCONTEXT ContextRecord,
+ PVOID DispatcherContext)
+
+ This was found experimentally to always be at offset 56 of the
+ context frame in all cases handled by this implementation.
+
+ 3) When we have the signal context we just have to save some registers
+ and set the return address based on the program counter (Eip).
+
+ Note that this implementation follows closely the same principles as the
+ GNU/Linux and OSF ones. */
