get_uncond_jump_length()

int get_uncond_jump_length ( void )

extern

Return the length of unconditional jump instruction.   

References emit_jump_insn(), emit_label(), end_sequence(), gcc_assert, gen_label_rtx(), get_attr_min_length(), INT_MAX, trace::length, start_sequence(), and targetm.

Referenced by duplicate_computed_gotos(), reorder_basic_blocks_software_trace_cache(), and try_shrink_wrapping().

insert_section_boundary_note()

void insert_section_boundary_note ( void )

extern

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.
