This reverts commit 62e77f56f0.
(except for ChangeLog and a bugfix in minimal_symbol_reader::install)
As agreed on the mailing list, now that GDB 9 has branched, this patch
reverts the change to set worker-threads to zero. After this patch,
multithreaded minsym demangling will be enabled again by default.
gdb/ChangeLog:
2019-12-13 Christian Biesinger <cbiesinger@google.com>
* maint.c (n_worker_threads): Default to -1.
(worker_threads_disabled): Remove function.
* maint.h (worker_threads_disabled): Remove function.
* minsyms.c (minimal_symbol_reader::record_full): Don't call
symbol_set_names here if worker_threads_disabled () is true.
