From f84f68b2deb89b8be9247d9a6e18eab38708fe23 Mon Sep 17 00:00:00 2001 From: msebor Date: Mon, 30 Jan 2017 23:15:40 +0000 Subject: [PATCH] gcc/ChangeLog: * gimple-ssa-sprintf.c (fmtresult::adjust_for_width_or_precision): Move constant to the right of a relational operator. (get_mpfr_format_length, format_character, format_string): Ditto.
