Field Documentation

eh_region leh_state::cur_region

     What's "current" while constructing the eh region tree.  These
     correspond to variables of the same name in cfun->eh, which we
     don't have easy access to.  

eh_region leh_state::ehp_region

     What's "current" for the purposes of __builtin_eh_pointer.  For
     a CATCH, this is the associated TRY.  For an EH_FILTER, this is
     the associated ALLOWED_EXCEPTIONS, etc.  

struct leh_tf_state* leh_state::tf

     Processing of TRY_FINALLY requires a bit more state.  This is
     split out into a separate structure so that we don't have to
     copy so much when processing other nodes.
