Subject: glsl: Fail the build if the grammar contains shift/reduce errors.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4ab7fc9ec345eab7a019174d513a918626c61dcf;p=mesa.git

glsl: Fail the build if the grammar contains shift/reduce errors.

When working on a parser, it's very easy to accidentally introduce
new shift/reduce conflicts.  Failing the build guarantees they'll
be noticed and fixed.
