+Subject: [PATCH 2/2] 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)

-AMDGPU: Fix an interaction between WQM and polygon stippling
-
-Summary:
-This fixes a rare bug in polygon stippling with non-monolithic pixel shaders.
-
-The underlying problem is as follows: the prolog part contains the polygon
-stippling sequence, i.e. a kill. The main part then enables WQM based on the
-_reduced_ exec mask, effectively undoing most of the polygon stippling.
-
-Since we cannot know whether polygon stippling will be used, the main part
-of a non-monolithic shader must always return to exact mode to fix this
-problem.
