However, ARM is concerned + * that the branch-to-indirect-branch that is implied by using a PLT, + * as required by IFUNC, is too much overhead for smaller cpus. + * + * (3) Statically predicted direct branches. This is the approach that + * is taken here. These functions are linked into every DSO that uses them. + * All of the symbols are hidden, so that the functions are called via a + * direct branch. The choice of LSE vs non-LSE is done via one byte load + * followed by a well-predicted direct branch.
