Subject: * linux-proc.c (struct linux_corefile_thread_data): Add num_notes
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8acc2935383b05b6ae4626dac433883c21381cfb;p=binutils-gdb.git

* linux-proc.c (struct linux_corefile_thread_data): Add num_notes
member.
(linux_corefile_thread_callback): Increase args->num_notes.
(linux_make_note_section): Initialize thread_args.num_notes, and
use it to determine whether notes for any threads were created.
