— GIMPLE function: gimple gimple_build_switch ( nlabels, tree index, tree default_label, ...)

Build a GIMPLE_SWITCH statement. NLABELS are the number of labels excluding the default label. The default label is passed in DEFAULT_LABEL. The rest of the arguments are trees representing the labels. Each label is a tree of code CASE_LABEL_EXPR.

— GIMPLE function: gimple gimple_build_switch_vec (tree index, tree default_label, VEC(tree,heap) *args)

This function is an alternate way of building GIMPLE_SWITCH statements. INDEX and DEFAULT_LABEL are as in gimple_build_switch. ARGS is a vector of CASE_LABEL_EXPR trees that contain the labels.

— GIMPLE function: unsigned gimple_switch_num_labels (gimple g)

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

— GIMPLE function: void gimple_switch_set_num_labels (gimple g, unsigned nlabels)

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

— GIMPLE function: tree gimple_switch_index (gimple g)

Return the index variable used by the switch statement G.

— GIMPLE function: void gimple_switch_set_index (gimple g, tree index)

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

— GIMPLE function: tree gimple_switch_label (gimple 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 (gimple 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 (gimple g)

Return the default label for a switch statement.

— GIMPLE function: void gimple_switch_set_default_label (gimple g, tree label)

Set the default label for a switch statement.
