12.7.1 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: 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) ¶

Return true if statement G has register or memory operands.

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) ¶

Set OPS to be the set of VDEF operands for statement G.

GIMPLE function: bitmap gimple_loaded_syms (gimple g) ¶

Return the set of symbols loaded by statement G. Each element of the set is the DECL_UID of the corresponding symbol.

GIMPLE function: bitmap gimple_stored_syms (gimple g) ¶

Return the set of symbols stored by statement G. Each element of the set is the DECL_UID of the corresponding symbol.

GIMPLE function: bool gimple_modified_p (gimple g) ¶

Return true if statement G has operands and the modified field has been set.

GIMPLE function: bool gimple_has_volatile_ops (gimple stmt) ¶

Return true if statement STMT contains volatile operands.

GIMPLE function: void gimple_set_has_volatile_ops (gimple stmt, bool volatilep) ¶

Return true if statement STMT contains volatile operands.

GIMPLE function: void update_stmt (gimple s) ¶

Mark statement S as modified, and update it.

GIMPLE function: void update_stmt_if_modified (gimple s) ¶
