The attached patch fixesgcc/testsuite/g++.dg/debug/dwarf2/template-func-params-7.C.

The problem is that DW_TAG_GNU_formal_parameter_pack DIEs are generatedmultiple times (once for early dwarf and once for late dwarf). Fixed byonly outputting in early dwarf.


Tested with GCC and GDB testsuites.

Committed to branch.
