From 8d4973a1c01d4b38871fbc6631e1fdd20e6c9e90 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 10 Jan 2017 16:48:03 -0800 Subject: gcc-plugins: add PASS_INFO and build_const_char_string() This updates the GCC plugins gcc-common.h from PaX Team to include more helpers and header files, specifically adds the PASS_INFO() macro to make plugin declarations nicer and a helper for proper const string building.
