[Pkg-opencl-devel] Bug#873417: pocl: Please update to llvm-toolchain 4.0 or, better, 5.0

Followup-For: Bug #873417

Hi,

I got distracted from pocl over the holidays, but today I finally took a
look again.
This is the current self test result matrix of the different pocl and llvm
versions on amd64 and i386:

			amd64	i386		testsuite time (amd64)
(there is only VECMATHLIB, no SLEEF)
pocl 0.14 / llvm 3.9	pass	pass		 205.87 sec
pocl 0.14 / llvm 4.0	pass	fail 12		2676.44 sec

-DENABLE_VECMATHLIB=ON (non-default)
pocl 1.0 / llvm 3.9	pass	pass		 130.87 sec
pocl 1.0 / llvm 4.0	pass	fail 10		2950.16 sec
pocl 1.0 / llvm 5.0	pass	fail 11		3952.99 sec

-DENABLE_SLEEF=ON (default)
pocl 1.0 / llvm 3.9	pass	fail 1		 172.41 sec
pocl 1.0 / llvm 4.0	pass	fail 1		 127.27 sec
pocl 1.0 / llvm 5.0	pass	fail 2		 121.52 sec


pocl 0.14 / llvm 4.0

89% tests passed, 12 tests failed out of 111

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 (OTHER_FAULT)
        110 - examples/trig (SEGFAULT)
        111 - EinsteinToolkit (OTHER_FAULT)

examples/scalarwave and EinsteinToolkit are fixed by commit
0d5683c68cda1401b66243c74d4f798ea2b2280f, which is not backportable to 0.14


pocl 1.0 / llvm 4.0 -DENABLE_VECMATHLIB=ON

The following tests FAILED:

Looks like we need to move to pocl 1.0 and llvm 4.0, unfortunately
that will need another pass through NEW, since the SOVERSION was bumped.
