Subject: nir/lower_io_to_temporaries: don't set compact on shadow vars
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4df93a54f18ff8baca1d7a1b395c1fa70d65a9bb;p=mesa.git

nir/lower_io_to_temporaries: don't set compact on shadow vars

The compact flag doesn't make sense on local variables, since the
packing on them is up to the driver. This fixes nir_validate assertions
in some cases, particularly when lower_io_to_temporaries is used on
per-vertex inputs/outputs.
