Subject: gdb: extra debug output in thread.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=58fd1204aa0f66dd2df30f673c9441e0265b8515;p=binutils-gdb.git

gdb: extra debug output in thread.c

Add some extra 'threads' debug in a couple of places in thread.c.
I've also added an additional gdb_assert in one case.
