Subject: util: Make unreachable at least be an assert
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=62d5b4b03aa63582cf0801d306d7ca055cca40a0;p=mesa.git

util: Make unreachable at least be an assert

Previously, if __builtin_unreachable() was unavailable, the
unreachable macro was defined to do nothing. We do better here, by at
least still making it an assert.
