/* Each architecture that supports SFrame may need to define several
|
|
macros to handle exceptional cases during stack backtracing.
|
|
|
|
MD_DECODE_SIGNAL_FRAME(frame) should recover frame information when
|
|
a signal-related exception occurs. The input frame must contain a
|
|
valid program counter (PC) field. On success, the macro should
|
|
return _URC_NO_REASON.
|
|
|
|
MD_DETECT_OUTERMOST_FRAME(frame) is used to detect the outermost
|
|
stack frame. It returns _URC_NO_REASON upon successful
|
|
detection.
|
|
|
|
The FRAME structure is defined in sysdeps/generic/sframe.h */
