Subject: Remove a use of is_mi_like_p from tracepoint.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f3c6ababac34f3a291997f8d5ea6a63949b58b87;p=binutils-gdb.git

Remove a use of is_mi_like_p from tracepoint.c

This removes a use of is_mi_like_p and changes a printf_filtered into
a call to ui_out::text.

ChangeLog
2018-04-30  Tom Tromey  <tom@tromey.com>

	* tracepoint.c (tvariables_info_1): Remove use of is_mi_like_p.
