[Mesa-dev] [PATCH 15/21] etnaviv: compiler: ignore nir_instr_type_ssa_undef

[Philipp Zabel]

From: Michael Tretter <m.tretter at pengutronix.de>

Ignore ssa_undef nir instructions when generating code, because all
users of the undefined values are removed and undefined values are not
used. The instructions should be removed while rewriting the users of
undefined variables, but are not removed yet.
