// can be fixed
|

//
|

// - the resize-list starts empty at beginning of user-shader compilation, it does
|

// not have built-ins in it
|

|
//
|

|
// - on built-in array use: copyUp() symbol and add it to the resize-list
|
||||||
|
//
|
||||||
|
// - on user array declaration: add it to the resize-list
|
||||||
|
//
|
||||||
|
// - on block redeclaration: copyUp() symbol and add it to the resize-list
|
||||||
|
// * note, that appropriately gives an error if redeclaring a block that
|
||||||
|
// was already used and hence already copied-up
|
||||||
|
//
|
||||||
|
// - on seeing a layout declaration that sizes the array, fix everything in the
|
||||||
|
// resize-list, giving errors for mismatch
|
||||||
|
//
|
||||||
|
// - on seeing an array size declaration, give errors on mismatch between it and previous
|
||||||
|
// array-sizing declarations
