Bug#892426: pocl: FTBFS on most non-x86 architectures: 12-16% of tests pass

Source: pocl
Version: 1.1~rc2-1
Severity: normal
Tags: upstream
User: [email protected]
Usertags: mips mips64el mipsel

Builds of pocl for most non-x86 architectures, including several
release architectures, failed with heavy test suite errors: between
12% and 16% of tests passed, depending on the architecture [1].  The
only exceptions are arm64, which succeeded, and armhf, on which 43% of
tests passed [2] -- still not great, but better.

More specifically, the failures in question occurred on armel, mips,
mips64el, mipsel, ppc64el, s390x, and the non-release architectures
powerpc, ppc64, and sparc64.  94 tests failed identically on all nine
of these architectures, as detailed below.  In addition, some tests
failed on only a subset of architectures:

  25 - kernel/test_shuffle_half (Failed): armel
  46/47 - regression/infinite_loop_REPL (Failed): sparc64
  60/61 - regression/infinite_loop_LOOPS (Failed): sparc64
  67/68 - regression/passing_a_constant_array_as_an_arg (Failed): sparc64
  79/80 - runtime/test_event_cycle (Failed): powerpc
  83/84 - runtime/clCreateKernel (Failed): sparc64
  84/85 - runtime/clGetKernelArgInfo (Failed): sparc64
  113/114 - examples/example1_dot_product (Child aborted): all but sparc64
  114/115 - examples/example2_matrix_transpose (Child aborted): all but sparc64
  115/116 - examples/example2_matrix_transpose_alocals (Child aborted): all but sparc64
  116/117 - poclcc (Child aborted): all but sparc64
  118/119 - examples/trig (Child aborted): all but sparc64
  119/120 - EinsteinToolkit (Child aborted): all but mips*
  120/121 - EinsteinToolkit_SubDev (Child aborted): all but mips*

NB: Test numbers vary somewhat because kernel/test_shuffle_half is #25
on armel and does not exist on the other eight affected architectures.

Could you please take a look?

Thanks!
