	* buildsym.c (end_symtab_1): Split it to ...
	(end_symtab_get_static_block): ... this ...
	(end_symtab_from_static_block): ... and this function.
	(end_symtab, end_expandable_symtab): Call them.
	* buildsym.h (end_symtab_get_static_block)
	(end_symtab_from_static_block): New declarations.
	* dwarf2read.c (process_full_comp_unit): New variable static_block.
	Set its valid CU ranges.

gdb/testsuite/
	* gdb.dwarf2/dw2-minsym-in-cu.S: New file.
