Argument Buffer Array Padding incorrect by unused image arrays in 1.3.296

[andreasschultes]

The padding for an unused binding is incorrect created with array size of 1 instead of the right array size

Defintion in fragment shader:

layout(binding = 1,set = 0) uniform sampler ASampler;  // unused or comment out, used in vertex shader
layout(binding = 2,set = 0) uniform sampler BSampler;
layout(binding = 3,set = 0) uniform utexture2D A_Array[128]; // unused or comment out, used in vertex shader
layout(binding = 4,set = 0) uniform texture2D B_Array[128];

Generated output extracted from XCode capture

struct spvDescriptorSetBuffer0
{
    constant void* _m0_pad [[id(0)]];
    constant void* _m1_pad [[id(1)]];
    sampler _m2_pad [[id(2)]];
    sampler BSampler [[id(3)]];
    array<texture2d<float>, 1> _m4_pad [[id(4)]]; // type maybe uint here
    array<texture2d<float>, 128> B_Array [[id(132)]];
};

XCODE View of the fragment buffer, shows the content _m4_pad[0] = A_Array [0], B_Array[0] = A_Array[1], ..., B_Array[127] = B_Array[0]
Next line starts probably with _m0_pad = B_Array[1] address

Accessing A_Array in shader changes the structure spvDescriptorSetBuffer0 to the right array size and everything is correct.

struct spvDescriptorSetBuffer0
{
    constant void* _m0_pad [[id(0)]];
    constant void* _m1_pad [[id(1)]];
    sampler ASampler [[id(2)]];
    sampler BSampler [[id(3)]];
    array<texture2d<uint>, 128> A_Array [[id(4)]]; 
    array<texture2d<float>, 128> B_Array [[id(132)]];
};
