+Subject: [PATCH 1/2] [CUDA] Improve clang's ability to detect recent CUDA
+ versions.
+
+CUDA-11.1 does not carry version.txt which causes clang to assume that it's
+CUDA-7.0, which used to be the only CUDA version w/o version.txt.
+
+In order to tell CUDA-7.0 apart from the new versions, clang now probes for the
+presence of libdevice.10.bc which is not present in the old CUDA versions.
+
+This should keep Clang working for CUDA-11.1.

-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)

+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)
