Subject: i965/vec4: fix get_nir_dest() to use DF type for 64-bit destinations
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a8318b120e53518ae4d933acd876b8dbd3871e0c;p=mesa.git

i965/vec4: fix get_nir_dest() to use DF type for 64-bit destinations

v2: Make dst_reg_for_nir_reg() handle this for nir_register since we
    want to have the correct type set before we call offset().
