Hi,

vector types are represented as array types with DW_AT_GNU_vector attribute in 
the debug info and a range [0 .. TYPE_VECTOR_SUBPARTS - 1].  That's obviously 
skewed toward the C family of languages, therefore the attached patch changes 
the lower bound to the default for the language of the CU, if any.

Tested on x86-64/Linux, OK for the mainline?


gcc/
	* dwarf2out.cc (gen_array_type_die): Use the default lower bound of
	the language for vector types.
