Detailed Description

   A landing pad for a given exception region.  Any transfer of control
   from the EH runtime to the function happens at a landing pad.  

Field Documentation

int eh_landing_pad_d::index
rtx eh_landing_pad_d::landing_pad
     At the rtl level, the location to which the runtime will transfer
     control.  This differs from the post-landing-pad in that the target's
     EXCEPTION_RECEIVER pattern will be expanded here, as well as other
     bookkeeping specific to exceptions.  There must not be normal edges
     into the block containing the landing-pad label.

struct eh_landing_pad_d* eh_landing_pad_d::next_lp
     The linked list of all landing pads associated with the region.  

Referenced by output_eh_try_list(), and record_stmt_eh_region().

tree eh_landing_pad_d::post_landing_pad
     At the gimple level, the location to which control will be transferred
     for this landing pad.  There can be both EH and normal edges into the
     block containing the post-landing-pad label.  

Referenced by do_return_redirection(), execute_lower_eh_dispatch(), lower_eh_constructs(), and make_goto_expr_edges().

struct eh_region_d* eh_landing_pad_d::region
     The region with which this landing pad is associated.
