   1 # test for little endian
   2 #
   3 # This test has been observed to fail on 32-bit architectures (see e.g.
   4 # https://github.com/llvm/llvm-project/issues/62184). Since we're aiming to
   5 # bring up JITLink support for ppc64{le} anyway (see
   6 # https://github.com/llvm/llvm-project/issues/62253) I've opted to just disable
   7 # it on 32-bit architectures for now.
   8 # REQUIRES: llvm-64-bits
