Subject: nv50/ir: 64-bit splitting fixes
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=daa0fd7843dfc3f2f209a1b755df01f4dbc8122f;p=mesa.git

nv50/ir: 64-bit splitting fixes

Take reading shader outputs into account, and use setFlagsDef for the
carry since we rely on having i->flagsDef being set.
