/* 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. */
