allow the target to label code fragments generated by partitioning.
* target.def (function_switched_text_sections): New Hook.
* doc/tm.texi Regenerated.
* doc/tm.texi.in (TARGET_ASM_FUNCTION_SWITCHED_TEXT_SECTIONS)
New.
* final.c (default_function_switched_text_sections): New.
(final_scan_insn): Call function_switched_text_sections when a mid-function section
change occurs.
* output.h (default_function_switched_text_sections): Declare.
* config/darwin-protos.h (darwin_function_switched_text_sections) : Likewise.
* config/darwin.c (darwin_function_switched_text_sections): New.
