Function Documentation

void expand_phi_nodes ( struct ssaexpand sa)
void finish_out_of_ssa ( struct ssaexpand sa)
static gimple get_gimple_for_ssa_name ( )
   If TER decided to forward the definition of SSA name EXP this function
   returns the defining statement, otherwise NULL.  
static rtx get_rtx_for_ssa_name ( )
   Returns the RTX expression representing the storage of the outof-SSA
   partition that the SSA name EXP is a member of.
