re PR rtl-optimization/34999 (Incorrect FDE entries with hot/cold code section splitting (partition_hot_cold_basic_blocks))
PR rtl-optimization/34999
* dwarf2out.c (struct dw_fde_struct): Add dw_fde_switch_cfi
and dw_fde_switched_cold_to_hot fields.
(output_cfi_p): New function.
(output_call_frame_info): If fde->dw_fde_switched_sections,
output 2 FDEs instead of one with corrupted header.
(dwarf2out_do_cfi_startproc): New function.
(dwarf2out_begin_prologue): Use it. Initialize fde->dw_fde_switch_cfi
and fde->dw_fde_switched_cold_to_hot.
(dwarf2out_switch_text_section): Compute
fde->dw_fde_switched_cold_to_hot. Switch to new text section here.
If dwarf2out_do_cfi_asm, emit .cfi_endproc before it and call
dwarf2out_do_cfi_startproc plus emit again currently active CFI insns.
Otherwise, compute fde->dw_fde_switch_cfi.
