/* 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. */
