+
+- Improve handling of constants and their initializers. Constant initializers
+ should never generate any code. This is trival for scalar constants. It is
+ also trivial for arrays, matrices, and vectors that are accessed with
+ constant index values. For others it is more complicated. Perhaps these
+ cases should be silently converted to uniforms?
+
+- Implement support for ir_binop_dot in ir_algebraic.cpp. Perform
+ transformations such as "dot(v, vec3(0.0, 1.0, 0.0))" -> v.y.
+
+1.30 features:
+
+- Implement AST-to-HIR conversion of bit-shift operators.
+
+- Implement AST-to-HIR conversion of bit-wise {&,|,^,!} operators.
+
+- Implement AST-to-HIR conversion of switch-statements
+ - switch
+ - case
+ - Update break to correcly handle mixed nexting of switch-statements
+ and loops.
+
+- Handle currently unsupported constant expression types
+ - ir_unop_bit_not
+ - ir_binop_mod
+ - ir_binop_lshift
+ - ir_binop_rshift
+ - ir_binop_bit_and
+ - ir_binop_bit_xor
+ - ir_binop_bit_or
+
+- Implement support for 1.30 style shadow compares which only return a float
+ instead of a vec4.
+
+- Implement support for gl_ClipDistance. This is non-trivial because
+ gl_ClipDistance is exposed as a float[8], but all hardware actually
+ implements it as vec4[2].
