... done as below ...

It should be possible for Rainer to define  
TARGET_ASM_TM_CLONE_TABLE_SECTION_NAME to NULL, and have varasm use  
the normal data section for tm_clone_table sections.    One might wish  
to re-adjust testsuite/gcc.dg/tm/20100615.c if that is done.


OK for trunk?

gcc:

	* target.def (tm_clone_table_section_name): New hook.
	* doc/tm.texi.in (TARGET_ASM_TM_CLONE_TABLE_SECTION_NAME): Define.
	* doc/tm.texi: Regenerate.
	* varasm.c (dump_tm_clone_pairs): Use target  
tm_clone_table_section_name if
	available, if that is NULL fall back to the data section.
	* config/darwin.h (TARGET_ASM_TM_CLONE_TABLE_SECTION_NAME): New.


gcc/testsuite:

	* gcc.dg/tm/20100615.c: Adjust for Darwin tm_clone_table section name.
