How to user Offline compiler with Vulkan Module?

im trying to profile a shader made in Unity and compiled to vulkan.

I had no problems before with opengl but i quite dont understand how to do the same with vulkan module.

Im coping the module to another file and saving as frag.spv

malioc.exe --spirv -c Mali-T760 --fragment C:\XXX\frag.spv

The erro i get is, SPIR-V header not recognized

Unity file look like this;

Disassembly for Fragment:
// Module Version 10000
// Generated by (magic number): 80006
// Id's are bound by 370

                              Capability Shader
               1:             ExtInstImport  "GLSL.std.450"
                              MemoryModel Logical GLSL450
                              EntryPoint Fragment 4  "main" 22 40 361

                              Name 40  "vs_TEXCOORD2"
                              Decorate 9 RelaxedPrecision
                              Decorate 12 RelaxedPrecision
                              Decorate 12 DescriptorSet 0
                              Decorate 12 Binding 2
                              Decorate 13 RelaxedPrecision
                              Decorate 16 RelaxedPrecision
                              Decorate 16 DescriptorSet 0
                              Decorate 16 Binding 0
                              Decorate 17 RelaxedPrecision
                              Decorate 22(vs_TEXCOORD1) Location 0
                              Decorate 26 RelaxedPrecision

...

Any ideas?
