Author: Neil Roberts <nrobe...@igalia.com> Date: Wed Mar 21 20:34:37 2018 +0100 nir/builder: Add a nir_imm_floatN_t helper This lets you easily build float immediates just given the bit size. If we have this single place here to handle this then it will be easier to add support for 16-bit floats later.
