Hi Artem,

The test "gfx7_asm_all.s" is failing because of a global-buffer-overflow
AddressSanitizer error on our Asan+Ubsan bot at
http://lab.llvm.org:8080/green/job/clang-stage2-cmake-RgSan/. The output of
the failing test that I obtained from
http://lab.llvm.org:8080/green/job/clang-stage2-cmake-RgSan_check/2915/consoleFull
is
shown below:

Command Output (stderr):
