From: Arnaldo Carvalho de Melo Date: Thu, 5 Aug 2010 22:28:27 +0000 (-0300) Subject: perf ui: Add search by name/addr to the map__browser X-Git-Tag: firefly_0821_release~9833^2~776^2~8^2~4 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=80d50cae1b9cc958171c36fffc7357a5abad808c;p=firefly-linux-kernel-4.4.55.git perf ui: Add search by name/addr to the map__browser Only in verbose mode so as not to bloat struct symbol too much. The key used is '/', just like in vi, less, etc. More work is needed to allocate space on the symbol in a more clear way. This experiment shows how to do it for the hist_browser, in the main window.
