[PATCH 0/1] Handle undnamed template tags in GDB

[Nils-Christian Kempke <nils-christian.kempke@intel.com>]

Hi,

please find attached a patch designed to make GDB recored template tags
like DW_TAG_template_type_parameter and DW_TAG_tempolate_value_parameter
even if they do not have a name in the compiler's DWARF.

According to DWARF 5 unnnamed template TAGs are valid DWARF.  However,
GDB does not record symbols that do not have names and as such, did not
record these template arguments.

This patch adds an artificial naming scheme for unnamed template TAGs.
It fixes a reported bug and improves GDB's handling of templates.


Tested on x86-64 Ubuntu 20 with unix, unix/-m32, native-gdbserver and
native-extended-gdbserver.

Cheers,
Nils
