12.8.27 GIMPLE_SWITCH ¶

GIMPLE function: gswitch *gimple_build_switch (tree index, tree default_label, vec<tree> *args) ¶

Build a GIMPLE_SWITCH statement. INDEX is the index variable to switch on, and DEFAULT_LABEL represents the default label. ARGS is a vector of CASE_LABEL_EXPR trees that contain the non-default case labels. Each label is a tree of code CASE_LABEL_EXPR.

GIMPLE function: unsigned gimple_switch_num_labels ( const gswitch *g) ¶

Return the number of labels associated with the switch statement G.

GIMPLE function: void gimple_switch_set_num_labels (gswitch *g, unsigned nlabels) ¶

Set NLABELS to be the number of labels for the switch statement G.

GIMPLE function: tree gimple_switch_index (const gswitch *g) ¶

Return the index variable used by the switch statement G.

GIMPLE function: void gimple_switch_set_index (gswitch *g, tree index) ¶

Set INDEX to be the index variable for switch statement G.

GIMPLE function: tree gimple_switch_label (const gswitch *g, unsigned index) ¶

Return the label numbered INDEX. The default label is 0, followed by any labels in a switch statement.

GIMPLE function: void gimple_switch_set_label (gswitch *g, unsigned index, tree label) ¶

Set the label number INDEX to LABEL. 0 is always the default label.

GIMPLE function: tree gimple_switch_default_label ( const gswitch *g) ¶

Return the default label for a switch statement.

GIMPLE function: void gimple_switch_set_default_label (gswitch *g, tree label) ¶

Set the default label for a switch statement.
