Subject: gallivm: Remove dead code in lp_build_compare_ext.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0ac316470813b4f2e825ff4befbbf2135cccce94;p=mesa.git

gallivm: Remove dead code in lp_build_compare_ext.

There are earlier returns for PIPE_FUNC_NEVER and PIPE_FUNC_ALWAYS. The
switch value of 'func' cannot be either of those values.

Fixes "Logically dead code" defects reported by Coverity.
