* util/hash_table: Rework the API to know about hashingJason Ekstrand2014-12-143-10/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the hash_table API required the user to do all of the hashing of keys as it passed them in. Since the hashing function is intrinsically tied to the comparison function, it makes sense for the hash table to know about it. Also, it makes for a somewhat clumsy API as the user is constantly calling hashing functions many of which have long names. This is especially bad when the standard call looks something like _mesa_hash_table_insert(ht, _mesa_pointer_hash(key), key, data); In the above case, there is no reason why the hash table shouldn't do the hashing for you. We leave the option for you to do your own hashing if it's more efficient, but it's no longer needed. Also, if you do do your own hashing, the hash table will assert that your hash matches what it expects out of the hashing function. This should make it harder to mess up your hashing. v2: change to call the old entrypoint "pre_hashed" rather than "with_hash", like cworth's equivalent change upstream (change by anholt, acked-in-general by Jason).

* glsl: invariant qualifier is not valid for shader inputs in GLSL ES 3.00Samuel Iglesias Gonsalvez2014-12-092-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | GLSL ES 3.00 spec, chapter 4.6.1 "The Invariant Qualifier", Only variables output from a shader can be candidates for invariance. This includes user-defined output variables and the built-in output variables. As only outputs can be declared as invariant, an invariant output from one shader stage will still match an input of a subsequent stage without the input being declared as invariant. This patch fixes the following dEQP tests: dEQP-GLES3.functional.shaders.qualification_order.variables.valid.invariant_interp_storage_precision dEQP-GLES3.functional.shaders.qualification_order.variables.valid.invariant_interp_storage dEQP-GLES3.functional.shaders.qualification_order.variables.valid.invariant_storage_precision dEQP-GLES3.functional.shaders.qualification_order.variables.valid.invariant_storage dEQP-GLES3.functional.shaders.qualification_order.variables.invalid.invariant_interp_storage_precision_invariant_input dEQP-GLES3.functional.shaders.qualification_order.variables.invalid.invariant_interp_storage_invariant_input dEQP-GLES3.functional.shaders.qualification_order.variables.invalid.invariant_storage_precision_invariant_input dEQP-GLES3.functional.shaders.qualification_order.variables.invalid.invariant_storage_invariant_input No piglit regressions observed. v2: - Add spec content in the code Signed-off-by: Samuel Iglesias Gonsalvez <siglesias@igalia.com> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>
