-# This is for the minispecs files included in the hardened gcc-4.x
-# The specs files for hardenedno*, vanilla and for building the "specs" file.
-# SPECS_VER is expected to be the version of this patch, SPECS_GCC_VER

-# Note [implicitly enabled flags]
-# -------------------------------
-# Usually configure-based packages handle explicit feature requests
-# like
-# ./configure --enable-foo
-# as explicit request to check for support of 'foo' and bail out at
-# configure time.
-#
-# GCC does not follow this pattern and instead overrides autodetection
-# of the feature and enables it unconditionally.
-# See bugs:
-# https://gcc.gnu.org/PR85663 (libsanitizer on mips)
-# https://bugs.gentoo.org/661252 (libvtv on powerpc64)
-#
-# Thus safer way to enable/disable the feature is to rely on implicit
-# enabled-by-default state:
-# econf $(usex foo '' --disable-foo)
