Detailed Description

Field Documentation

basic_block gimple_statement_base::bb
inherited

[ WORD 3 ] Basic block holding this statement.

Referenced by gimple_call_arg_flags().

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.

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
int gimple_statement_eh_ctrl::region

[ WORD 1-6 ] : base class [ WORD 7 ] Exception region number.

Referenced by gimple_build_eh_else(), and gimple_build_resx().

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.
