Subject: Make warning usable earlier
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0d2f5c0791fda17ebbc503c5e7716fcb619318fc;p=binutils-gdb.git

Make warning usable earlier

warning will crash if called before the first call to set_width.  This
commit makes the warning usable from the moment gdb_stderr is set up.

gdb/ChangeLog:

	* utils.c (vwarning): Protect calls to target_terminal_ours
	and wrap_here.
