+Subject: [PATCH] Enable SSP and PIE by default
+
+This is a minimal set of changes needed to make clang use SSP and PIE by
+default on Arch Linux. Tests that were easy to adjust have been changed
+accordingly; only test/Driver/linux-ld.c has been marked as "expected
+failure" due to the number of changes it would require (mostly replacing
+crtbegin.o with crtbeginS.o).
+
+Doing so is needed in order to align clang with the new default GCC
+behavior in Arch which generates PIE executables by default and also
+defaults to -fstack-protector-strong. It is not meant to be a long term
+solution, but a simple temporary fix.
+
+Hopefully these changes will be obsoleted by the introduction upstream
+of a compile-time option (https://bugs.llvm.org/show_bug.cgi?id=13410)
