GIMPLE_SWITCH#

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.

unsigned gimple_switch_num_labels(const gswitch *g)#: Return the number of labels associated with the switch statement G.

void gimple_switch_set_num_labels(gswitch *g, unsigned nlabels)#: Set NLABELS to be the number of labels for the switch statement G.

tree gimple_switch_index(const gswitch *g)#: Return the index variable used by the switch statement G.

void gimple_switch_set_index(gswitch *g, tree index)#: Set INDEX to be the index variable for switch statement G.

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.

void gimple_switch_set_label(gswitch *g, unsigned index, tree label)#: Set the label number INDEX to LABEL. 0 is always the default label.

tree gimple_switch_default_label(const gswitch *g)#: Return the default label for a switch statement.

void gimple_switch_set_default_label(gswitch *g, tree label)#: Set the default label for a switch statement.
