GIMPLE_PHI#

unsigned gimple_phi_capacity(gimple g)#: Return the maximum number of arguments supported by GIMPLE_PHI G.

unsigned gimple_phi_num_args(gimple g)#: Return the number of arguments in GIMPLE_PHI G. This must always be exactly the number of incoming edges for the basic block holding G.

tree gimple_phi_result(gimple g)#: Return the SSA name created by GIMPLE_PHI G.

tree *gimple_phi_result_ptr(gimple g)#: Return a pointer to the SSA name created by GIMPLE_PHI G.

void gimple_phi_set_result(gphi *g, tree result)#: Set RESULT to be the SSA name created by GIMPLE_PHI G.

struct phi_arg_d *gimple_phi_arg(gimple g, index)#: Return the PHI argument corresponding to incoming edge INDEX for GIMPLE_PHI G.

void gimple_phi_set_arg(gphi *g, index, struct phi_arg_d *phiarg)#: Set PHIARG to be the argument corresponding to incoming edge INDEX for GIMPLE_PHI G.
