* meson: convert gtest to an internal dependencyDylan Baker2017-10-031-2/+2
| | | | | | | | | | | | In truth gtest is an external dependency that upstream expects you to "vendor" into your own tree. As such, it makes sense to treat it more like a dependency than an internal library, and collect it's requirements together in a dependency object. v2: - include with -isystem instead of setting compiler args (Eric) Signed-off-by: Dylan Baker <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | | The optimization as done in opt_copy_propagation would have to be removed in the next patch. If we just eliminate that optimization altogether, shader-db results, even on platforms that use NIR, are hurt quite substantially. I have not investigated why NIR isn't picking up the slack here.

* glsl/ast: Use ir_binop_equal instead of ir_binop_all_equalIan Romanick2017-10-021-15/+24
| | | | | | | | | | | | | | | The values being compared are scalars, so these are the same. While I'm here, simplify the run_default condition to just deref the flag (instead of comparing a scalar bool with true). There is a bit of extra change in this patch. When constructing an ir_binop_equal ir_expression, there is an assertion that the types are the same. There is no such assertion for ir_binop_all_equal, so passing glsl_type::uint_type with glsl_type::int_type was previously fine. A bunch of the code motion is to deal with that.
