SHADER compute comp SPIRV-ASM
;
; The shader below is based on the following GLSL shader:
;
; #version 450
;
; struct Pair {
; int first;
; int second;
; };
;
; const Pair constant_pair = { 100, 200 };
;
; layout (constant_id=0) const int constantFirst = 0;
;
; Pair spec_constant_pair = { constantFirst, 200 };
;
; layout(set=0, binding=0, std430) buffer InputBlock {
; int array[10];
; } inputValues;
;
; layout(set=0, binding=1, std430) buffer OutputBlock {
; int array[10];
; } outputValues;
;
; int add_first_and_second (int value, Pair p1, Pair p2) {
; return value + p1.first + p2.second;
; }
;
; void main() {
; uint idx = gl_GlobalInvocationID.x;
; outputValues.array[idx] = add_first_and_second(inputValues.array[idx], spec_constant_pair, constant_pair);
; }
;
; However, both the constant_pair and the spec_constant_pair have one of their members replaced by undefined values.
