|
- Handle constant expressions of (struct == struct)
|
|
|
|
- Handle constant expressions of (struct != struct)
|
|
|
|
- Add support to ir_constant for array constants Arrays can only be
|
|
- declared 'const' in GLSL 1.20+. This is because there are no
|
|
array constructors in GLSL 1.10, and any variable declared as
|
|
'const' must have an initializer.
|
|
|
|
- Handle constant expressions of (array == array)
|
|
|
|
- Handle constant expressions of (array != array)
|
|
|
|
- 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 non-void functions that lack a return statement
|
|
|
|
- Detect return statements with a type not matching the funciton's
|
|
return type.
|
|
|
|
- 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.
|
|
|
|
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.
