Oops, I meant sizeof(void*) - 5.

Hey All,
This is a very big topic in SPIR and probably a very controversial one as well. It includes dealing with 32 vs. 64 bit architectures and OpenCL "C" endianness.
We have written down some of the aspects, but of course did not cover everything - let's start a discussion on the portability and see where it takes us.
I suggest we start with the 32 vs. 64 bits discussion and then
