Created attachment 133652 [details] Debug log Compilation of the following kernel fails with assertion 'sel.hasDoubleType()': kernel void A(global double2* a) { a[0] = get_global_id(0); } ASSERTION FAILED: sel.hasDoubleType() at file ../backend/src/backend/gen_insn_selection.cpp, function void gbe::ConvertInstructionPattern::convertSmallIntsToDouble(gbe::Selection::Opaque&, const gbe::ir::ConvertInstruction&, bool&) const, line 6366 Device: Intel(R) HD Graphics Haswell GT2 Desktop Beignet version: 1.3 Full debug log attached.
This is expected (though the error message could be more explicit): double precision is not supported on Haswell (and is disabled by default even on hardware that does support it).
Sure, I can agree that the code may not be expected to compile. The reason I filed a bug however is because a compiler assertion, whether or not it contains a meaningful assertion message, does not seem like the appropriate response to an input. An error diagnostic and CL_BUILD_PROGRAM_FAILURE is the expected outcome.
