Detailed Description

code == GIMPLE_LABEL

GIMPLE_LABEL <LABEL> represents label statements. LABEL is a LABEL_DECL representing a jump target.

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.

tree gimple_statement_with_ops::op[1]

inherited

[ WORD 1-7 ] : base class [ WORD 8 ] Operand vector. NOTE! This must always be the last field of this structure. In particular, this means that this structure cannot be embedded inside another one.

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().

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.

struct use_optype_d* gimple_statement_with_ops_base::use_ops

inherited

[ WORD 1-6 ] : base class [ WORD 7 ] SSA operand vectors. NOTE: It should be possible to amalgamate these vectors with the operand vector OP. However, the SSA operand vectors are organized differently and contain more information (like immediate use chaining).

Referenced by gimple_in_ssa_p().

unsigned int gimple_statement_base::visited

inherited

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