12.6 Manipulating GIMPLE statements
This section documents all the functions available to handle each
of the GIMPLE instructions.
12.6.1 Common accessors
The following are common accessors for gimple statements.
— GIMPLE function: enum
gimple_code gimple_code (
gimple g)
Return the code for statement G.
— GIMPLE function: basic_block
gimple_bb (
gimple g)
Return the basic block to which statement G belongs to.
— GIMPLE function: tree
gimple_block (
gimple g)
Return the lexical scope block holding statement G.
— GIMPLE function: tree
gimple_expr_type (
gimple stmt)
Return the type of the main expression computed by STMT. Return
void_type_node if STMT computes nothing. This will only return
something meaningful for GIMPLE_ASSIGN, GIMPLE_COND and
GIMPLE_CALL. For all other tuple codes, it will return
void_type_node.
— GIMPLE function: enum
tree_code gimple_expr_code (
gimple stmt)
Return the tree code for the expression computed by STMT. This
is only meaningful for GIMPLE_CALL, GIMPLE_ASSIGN and
GIMPLE_COND. If STMT is GIMPLE_CALL, it will return CALL_EXPR.
For GIMPLE_COND, it returns the code of the comparison predicate.
For GIMPLE_ASSIGN it returns the code of the operation performed
by the RHS of the assignment.
— GIMPLE function: void
gimple_set_block (
gimple g, tree block)
Set the lexical scope block of G to BLOCK.
— GIMPLE function: location_t
gimple_locus (
gimple g)
Return locus information for statement G.
— GIMPLE function: void
gimple_set_locus (
gimple g, location_t locus)
Set locus information for statement G.
— GIMPLE function: bool
gimple_locus_empty_p (
gimple g)
Return true if G does not have locus information.
— GIMPLE function: bool
gimple_no_warning_p (
gimple stmt)
Return true if no warnings should be emitted for statement STMT.
— GIMPLE function: void
gimple_set_visited (
gimple stmt, bool visited_p)
Set the visited status on statement STMT to VISITED_P.
— GIMPLE function: bool
gimple_visited_p (
gimple stmt)
Return the visited status on statement STMT.
— GIMPLE function: void
gimple_set_plf (
gimple stmt, enum plf_mask plf, bool val_p)
Set pass local flag PLF on statement STMT to VAL_P.
— GIMPLE function: unsigned
int gimple_plf (
gimple stmt, enum plf_mask plf)
Return the value of pass local flag PLF on statement STMT.
— GIMPLE function: bool
gimple_has_ops (
gimple g)

— GIMPLE function: bool
gimple_has_mem_ops (
gimple g)
Return true if statement G has memory operands.
— GIMPLE function: unsigned
gimple_num_ops (
gimple g)
Return the number of operands for statement G.
— GIMPLE function: tree
*gimple_ops (
gimple g)
Return the array of operands for statement G.
— GIMPLE function: tree
gimple_op (
gimple g, unsigned i)
Return operand I for statement G.
— GIMPLE function: tree
*gimple_op_ptr (
gimple g, unsigned i)
Return a pointer to operand I for statement G.
— GIMPLE function: void
gimple_set_op (
gimple g, unsigned i, tree op)
Set operand I of statement G to OP.
— GIMPLE function: bitmap
gimple_addresses_taken (
gimple stmt)
Return the set of symbols that have had their address taken by
STMT.
— GIMPLE function: struct
def_optype_d *gimple_def_ops (
gimple g)
Return the set of DEF operands for statement G.
— GIMPLE function: void
gimple_set_def_ops (
gimple g, struct def_optype_d *def)
Set DEF to be the set of DEF operands for statement G.
— GIMPLE function: struct
use_optype_d *gimple_use_ops (
gimple g)
Return the set of USE operands for statement G.
— GIMPLE function: void
gimple_set_use_ops (
gimple g, struct use_optype_d *use)
Set USE to be the set of USE operands for statement G.
— GIMPLE function: struct
voptype_d *gimple_vuse_ops (
gimple g)
Return the set of VUSE operands for statement G.
— GIMPLE function: void
gimple_set_vuse_ops (
gimple g, struct voptype_d *ops)
Set OPS to be the set of VUSE operands for statement G.
— GIMPLE function: struct
voptype_d *gimple_vdef_ops (
gimple g)
Return the set of VDEF operands for statement G.
— GIMPLE function: void
gimple_set_vdef_ops (
gimple g, struct voptype_d *ops)
