--- Comment #3 from kinke <[email protected]> --- Oh, I've just seen that `cast(int4) someFloat4` is a reinterpret cast with both LDC and GDC, but not with DMD (=> conversion). So would need to uglify further to please DMD, rendering vector masks with FP vectors next to useless. That reinterpret-cast with LDC and GDC would be another difference from scalar vs. vector. While bitwise ops for a scalar FP type don't really make much sense, they are IMO key to making vector masks nice to work with in practice. Oh and LDC is apparently the only compiler allowing the most trivial of comparisons - identity comparisons (yielding a scalar bool). So the other non-bitop use case for such vector masks, manually reducing to a scalar (e.g., `mask is 0`) currently only works with LDC, and needs a full array comparison and boilerplate syntax with the other compilers (`mask.array == [0, 0, 0, 0]`). --
