New Revision: 314361
URL: http://llvm.org/viewvc/llvm-project?rev=314361&view=rev
Log:
Reverted r313993.
This patch produces a crash and hexagon_vector_loop_carried_reuse_constant.ll test fails on Windows (llvm-clang-x86_64-expensive-checks-win build bot).
Removed:
llvm/trunk/test/CodeGen/Hexagon/hexagon_vector_loop_carried_reuse_constant.ll
Modified:
