glsl: Prohibit illegal mixing of redeclarations inside/outside gl_PerVertex.
From section 7.1 (Built-In Language Variables) of the GLSL 4.10 spec: Also, if a built-in interface block is redeclared, no member of the built-in declaration can be redeclared outside the block redeclaration. We have been regarding this text as a clarification to the behaviour established for gl_PerVertex by GLSL 1.50, so we apply it regardless of GLSL version. This patch enforces the rule by adding an enum to ir_variable to track how the variable was declared: implicitly, normally, or in an interface block. Fixes piglit tests: - gs-redeclares-pervertex-out-after-global-redeclaration.geom - vs-redeclares-pervertex-out-after-global-redeclaration.vert - gs-redeclares-pervertex-out-after-other-global-redeclaration.geom - vs-redeclares-pervertex-out-after-other-global-redeclaration.vert - gs-redeclares-pervertex-out-before-global-redeclaration - vs-redeclares-pervertex-out-before-global-redeclaration Cc: "10.0" <[email protected]> v2: Don't set "how_declared" redundantly in builtin_variables.cpp. Properly clone "how_declared".
