Detailed Description

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.

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
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.

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.
