| /* 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. */ |
