From ff5101bf0dd39a12e9d5a40b2bfafee9248307a4 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 30 Sep 2014 04:10:12 +0000 Subject: [PATCH] Make -Q --help print param defaults and min/max values Make -Q --help print the --param default, min, max values, similar to how it does print the defaults for other flags. This is useful to let a option auto tuner automatically query all needed information abourt gcc params (previously it needed to access the .def file in the source) gcc/: 2014-09-29 Andi Kleen * opts.c (print_filtered_help): Print --param min/max/default with -Q.
