Expand description

We support the z-style augmentation defined by .eh_frame.

Fields§

§lsda: Option<DwEhPe>

A ‘L’ may be present at any position after the first character of the string. This character may only be present if ‘z’ is the first character of the string. If present, it indicates the presence of one argument in the Augmentation Data of the CIE, and a corresponding argument in the Augmentation Data of the FDE. The argument in the Augmentation Data of the CIE is 1-byte and represents the pointer encoding used for the argument in the Augmentation Data of the FDE, which is the address of a language-specific data area (LSDA). The size of the LSDA pointer is specified by the pointer encoding used.

§personality: Option<(DwEhPe, Pointer)>

A ‘P’ may be present at any position after the first character of the string. This character may only be present if ‘z’ is the first character of the string. If present, it indicates the presence of two arguments in the Augmentation Data of the CIE. The first argument is 1-byte and represents the pointer encoding used for the second argument, which is the address of a personality routine handler. The size of the personality routine pointer is specified by the pointer encoding used.

§fde_address_encoding: Option<DwEhPe>

A ‘R’ may be present at any position after the first character of the string. This character may only be present if ‘z’ is the first character of the string. If present, The Augmentation Data shall include a 1 byte argument that represents the pointer encoding for the address pointers used in the FDE.

§is_signal_trampoline: bool

True if this CIE’s FDEs are trampolines for signal handlers.
