| SkSLConstructorArrayCast.cpp |
|
3016 |
| SkSLConstructorArrayCast.h |
Represents the typecasting of an array. Arrays cannot be directly casted in SkSL (or GLSL), but
type narrowing can cause an array to be implicitly casted. For instance, the expression
`myHalf2Array == float[2](a, b)` should be allowed when narrowing conversions are enabled; this
constructor allows the necessary array-type conversion to be represented in IR.
These always contain exactly 1 array of matching size, and are never constant.

| SkSLConstructorCompound.cpp |
initial value |
7655 |
| SkSLConstructorCompound.h |
Represents a vector or matrix that is composed from other expressions, such as
`half3(pos.xy, 1)` or `mat3(a.xyz, b.xyz, 0, 0, 1)`
These can contain a mix of scalars and aggregates. The total number of scalar values inside the
constructor must always match the type's slot count. (e.g. `pos.xy` consumes two slots.)
The inner values must have the same component type as the vector/matrix.
|
2030 |
| SkSLConstructorCompoundCast.cpp |
|
4617 |

|
3064 |

in valid programs.
Method calls are only supported on effect-child types, and they all resolve to intrinsics
prefixed with '$', and taking the 'self' object as the last parameter. For example:
uniform shader child;
...
child.eval(xy) --> $eval(xy, child)
