[Pkg-opencl-devel] Bug#883613: pocl 0.14 test failures on i386

[Andreas Beckmann]

Source: pocl
Version: 0.14
Severity: serious
Control: block 873417 with -1

Hi,

pocl 0.14 builds and tests fine on amd64, but I still have test failures on i386:

The following tests FAILED:
         16 - kernel/test_fabs (Failed)
         69 - runtime/clBuildProgram (Failed)

That one happens all the time:

OK

and that one happens at least half of the time:

For llvm-3.9 the situation doe not improve:

The following tests FAILED:
          9 - kernel/test_hadd_loopvec (Failed)
         10 - kernel/test_hadd_loops (Failed)
         15 - kernel/test_rotate (Failed)
         16 - kernel/test_fabs (Failed)

Neither for llvm-4.0:

The following tests FAILED:
          3 - kernel/test_convert_type_1 (Failed)
          4 - kernel/test_convert_type_2 (Failed)
          5 - kernel/test_convert_type_4 (Failed)
          6 - kernel/test_convert_type_8 (Failed)
          7 - kernel/test_convert_type_16 (Failed)
         12 - kernel/test_length_distance (Failed)
         13 - kernel/test_fmin_fmax_fma (Failed)
         16 - kernel/test_fabs (Failed)
         18 - kernel/test_frexp_modf (Failed)
        109 - examples/scalarwave (SEGFAULT)
        110 - examples/trig (SEGFAULT)
        111 - EinsteinToolkit (SEGFAULT)

amd64 passes the tests in both cases (but the kernel tests seem to run much longer with 4.0)

pocl 0.14 does not support llvm-5.0


The experimental branch is up-to-date (for building with llvm-3.8).
