Fixed array arguments during conversion from HLSL to GLSL

[Majrusz]

Hello, I think I found a bug in HLSL2GLSLConverterLib where array members within an HLSL shader output structure are incorrectly translated into scalar (non-array) out variables in GLSL. This mismatch results in compilation error: error C1035: assignment of incompatible types.

Minimal Example

Vertex shader

struct VSInput {
    float3 pos : ATTRIB0;
};

struct PSInput {
    float4 pos : SV_POSITION;
    float4 offsets[2] : OFFSET; // here is the problematic array
};

void main(in VSInput VSIn, out PSInput PSIn) {
    PSIn.pos = float4(VSIn.pos, 1.0) + PSIn.offsets[0] + PSIn.offsets[1];
}

Code

    Diligent::IRenderDevice* RenderDevice = ...;
    std::string Source = ...;
    
    Diligent::ShaderCreateInfo ShaderCI;
    ShaderCI.SourceLanguage = Diligent::SHADER_SOURCE_LANGUAGE_HLSL;
    ShaderCI.CompileFlags = Diligent::SHADER_COMPILE_FLAG_PACK_MATRIX_ROW_MAJOR;
    ShaderCI.Desc.UseCombinedTextureSamplers = true;
    ShaderCI.Desc.ShaderType = Diligent::SHADER_TYPE_VERTEX;
    ShaderCI.Source = Source.c_str();

    Diligent::RefCntAutoPtr<Diligent::IShader> Shader;
    RenderDevice->CreateShader(ShaderCI, &Shader);

HLSL2GLSLConverterLib Output

// ...
struct VSInput {
    float3 pos;
};

struct PSInput {
    float4 pos;
    float4 offsets[2];
};

layout(location = 0) in float3 _vsin_VSIn_pos;
out float4 _PSIn_offsets; // <-------------------------- missing [2]

#define _RETURN_ {\
_SET_GL_POSITION(PSIn.pos);\
_PSIn_offsets = PSIn.offsets;\
return;}

void main() {
    VSInput VSIn;
    VSIn.pos = _vsin_VSIn_pos;
    PSInput PSIn;

    PSIn.pos = float4(VSIn.pos, 1.0) + PSIn.offsets[0] + PSIn.offsets[1];
_RETURN_
}

Error message 0(1209) : error C1035: assignment of incompatible types points to _RETURN_ (_PSIn_offsets = PSIn.offsets;)
