Subject: pan/bi: Remove nontrivial SPECIAL ops
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a6ae2d8f940df3d9e0b71b13336ca01e5b6a2c47;p=mesa.git

pan/bi: Remove nontrivial SPECIAL ops

These require a lot more handholding in the IR than we can deal with at
this stage; we need to restrict ourselves to frcp/sqrt.
