int get_uncond_jump_length

(

void

)

Return the length of unconditional jump instruction.

void insert_section_boundary_note

(

void

)

Determine which partition the first basic block in the function
   belongs to, then find the first basic block in the current function
   that belongs to a different section, and insert a
   NOTE_INSN_SWITCH_TEXT_SECTIONS note immediately before it in the
   instruction stream.  When writing out the assembly code,
   encountering this note will make the compiler switch between the
   hot and cold text sections.
