- Authentication-results: sourceware.org; auth=none
- References: <20180106002621.21099-1-tom@tromey.com>
This patch unifies new_symbol with new_symbol_full, replacing a
wrapper function with a default parameter.
2018-01-05 Tom Tromey <tom@tromey.com>
* dwarf2read.c (dwarf2_compute_name): Update comment.
(read_func_scope, read_variable): Update.
(new_symbol): Remove.
(new_symbol_full): Rename to new_symbol.
