Hi, Windows build of pocl is only compiling, it is not really functional
yet. I actually did run tests for curiosity and currently against llvm 3.6
it was passing 8 tests. I remember that there was maybe 20 tests passing
few months ago.
I started fixing Windows compatibility issues few months ago, when cmake
build system was being developed. So current version of windows build has
only the necessary modifications to make it compile with Visual Studio.
That was the first step to start bringing it to Windows.
Now I would like to setup buildbot to just make sure that all the new code
still compiles with Visual Studio. After that, when I or somebody else has
a spare moment, start picking low hanging fruits to make some more cases in
test suite to pass.
