Field Documentation

struct phi_arg_d gimple_statement_phi::args[1]

     [ WORD 9 ]  

basic_block gimple_statement_base::bb

inherited

     [ WORD 3 ]
     Basic block holding this statement.  

Referenced by gimple_call_arg_flags().

unsigned gimple_statement_phi::capacity

     [ WORD 1-6 ] : base class 

     [ WORD 7 ]  

unsigned gimple_statement_base::has_volatile_ops

inherited

     Nonzero if this statement contains volatile operands.  

location_t gimple_statement_base::location

inherited

     [ WORD 2 ]
     Locus information for debug info.  

unsigned gimple_statement_base::modified

inherited

     Nonzero if this statement has been modified and needs to have its
     operands rescanned.  

unsigned gimple_statement_phi::nargs

gimple gimple_statement_base::next

inherited

     [ WORD 4-5 ]
     Linked lists of gimple statements.  The next pointers form
     a NULL terminated list, the prev pointers are a cyclic list.
     A gimple statement is hence also a double-ended list of
     statements, with the pointer itself being the first element,
     and the prev pointer being the last.  

Referenced by gsi_insert_seq_nodes_after(), gsi_set_stmt(), and gsi_split_seq_after().

ENUM_BITFIELD (gimple_code) code unsigned int gimple_statement_base::no_warning

inherited

     [ WORD 1 ]
     Main identifying code for a tuple.  

     Nonzero if a warning should not be emitted on this tuple.  

unsigned int gimple_statement_base::nontemporal_move

inherited

     Nonzero if this tuple represents a non-temporal move.  

unsigned gimple_statement_base::num_ops

inherited

     Number of operands in this tuple.  

unsigned int gimple_statement_base::plf

inherited

     Pass local flags.  These flags are free for any pass to use as
     they see fit.  Passes should not assume that these flags contain
     any useful value when the pass starts.  Any initial state that
     the pass requires should be set on entry to the pass.  See
     gimple_set_plf and gimple_plf for usage.  

gimple gimple_statement_base::prev

inherited

Referenced by gsi_insert_seq_before(), gsi_insert_seq_nodes_after(), gsi_set_stmt(), and gsi_split_seq_after().

tree gimple_statement_phi::result

     [ WORD 8 ]  

unsigned int gimple_statement_base::subcode

inherited

     The SUBCODE field can be used for tuple-specific flags for tuples
     that do not require subcodes.  Note that SUBCODE should be at
     least as wide as tree codes, as several tuples store tree codes
     in there.  

Referenced by gimple_build_call_valist().

unsigned gimple_statement_base::uid

inherited

     UID of this statement.  This is used by passes that want to
     assign IDs to statements.  It must be assigned and used by each
     pass.  By default it should be assumed to contain garbage.  

unsigned int gimple_statement_base::visited

inherited

     Nonzero if this tuple has been visited.  Passes are responsible
     for clearing this bit before using it.
