Daan Dehing daa6bee7cf feat(shader): implement v_interp_p1ll_f16, v_interp_p1lv_f16 and v_interp_p2_f16 ... Decode the three VOP3 16-bit interpolation instructions (attribute, channel and high-half select in the src0 field, the I/J VGPR in src1, P0 or the first step's result in src2) and translate them with a new GetInterpolationParameterF16 IR value. It reads the selected 16-bit half of each vertex's parameter through VK_KHR_fragment_shader_barycentric, so P10 and P20 are vertex differences rounded to f16; both steps are a multiply and an add, as in the f32 forms. An input in FP16_INTERP_MODE whose low half is defaulted is still declared at its slot when its high half is read, and the high half takes its default from USE_DEFAULT_ATTR1 and DEFAULT_VAL_ATTR1. Without barycentrics, on an input without FP16_INTERP_MODE or on a pass-through input the instructions throw. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>		2026-10-08 23:36:04 +02:00
