Subject: ir_constant_expression: Implement equal/notEqual for booleans.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d12cb77d85ec726a67c2099c4105df63829b45a4;p=mesa.git

ir_constant_expression: Implement equal/notEqual for booleans.

Calls to equal(bvec, bvec) or notEqual(bvec, bvec) previously caused an
assertion.  Fixes piglit tests glsl-const-builtin-equal-bool and
glsl-const-builtin-notEqual-bool.
