That's here:
/* Run just enough of rest_of_compilation to get the insns emitted.
There's not really enough bulk here to make other passes such as
instruction scheduling worth while. Note that use_thunk calls
assemble_start_function and assemble_end_function. */
insn = get_insns ();
shorten_branches (insn);
