@cindex @code{cfi_fde_data} directive
|

@code{cfi_fde_data} is used to describe the compact unwind opcodes to be
|
||||
used for the current function. These are emitted inline in the

@code{.eh_frame_entry} section if small enough and there is no LSDA, or

@code{.cfi_lsda} defines LSDA and its encoding.

@var{encoding} must be a constant determining how the LSDA

should be encoded. If it is 255 (@code{DW_EH_PE_omit}), second

The table header and unwinding opcodes will be generated at this point,
