- Handle constant expressions of (struct == struct)
|
|
|
|
- Handle constant expressions of (struct != struct)
|
|
|
|
- Treat built-in functions with constant parameters as constant expressions.
|
|
- Rewrite all built-in functions return a single expression.
|
|
- Modify the HIR generator for functions to automatically inline built-in
|
|
functions durning translation.
|
|
- Care must be taken to handle both the 1.10 rules and the 1.20+ rules. In
|
|
1.10, built-in functions cannot be constant expressions.
|
|
|
|
- Detect code paths in non-void functions that don't reach a return statement
|
|
|
|
- Handle over-riding built-in functions
|
|
- Is the overload per-compilation unit or per-linked shader?
|
|
|
|
- Handle redeclaration of built-in variables
|
|
- Handle addition of qualifiers such as 'invariant' or 'centroid'.
|
|
- Handle resizing of arrays.
|
|
- Other? We'll have to look at the spec.
|
|
|
|
- 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?
|
|
|
|
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.
