Subject: nir/constant_folding: Get rid of a bit size switch statement
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b8197a01a96f5d15268ee5bab28637058f2f962a;p=mesa.git

nir/constant_folding: Get rid of a bit size switch statement

Now that nir_const_value is a scalar, we don't need the switch on bit
size in order to swizzle them properly.
