Lines Matching defs:half
44 * Additionally we create additional classes for half-regs, which
46 * sizes 1-4 (to deal w/ texture sample instructions output to half-
47 * reg). At the moment we don't create the higher order half-reg
48 * classes as half-reg frequently does not have enough precision
284 /* starting a6xx, half precision regs conflict w/ full precision regs: */
287 * conflicts between the first class of full and half regs:
290 /* NOTE there are fewer half class sizes, but they match the
368 size_to_class(unsigned sz, bool half, bool high)

971 /* some instructions need fix-up if dst register is half precision: */
1012 /* some instructions need fix-up if src register is half precision: */
