From ebe48ba0856dcccaa7a60d873c61e6f1f96f5887 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Thu, 21 Sep 2017 14:09:33 +0200 Subject: microblaze-tdep: Add ATTRIBUTE_PRINTF to microblaze_debug I am getting this warning with clang: /home/emaisin/src/binutils-gdb/gdb/microblaze-tdep.c:94:28: error: format string is not a string literal [-Werror,-Wformat-nonliteral] vprintf_unfiltered (fmt, args); ^~~ Adding ATTRIBUTE_PRINTF to microblaze_debug gets rid of it. Strangely, gcc doesn't warn about non-literal format strings when calling vprintf (or a vprintf-style function, like vprintf_unfiltered).
