If your format has to be more complicated than a raw binary image (which
TCC can generate with the -Wl,--oformat,binary option), then use ELF.

Yes the format is simple, it should contain:
- the generated code - global data section - relocation table No symbol table or other additional sections are necessary. But i will also have a look on the raw binary image of TCC to see if i
can use it.

Use ELF, it does exactly what you want - no need to handle symbols if you don't need them. An ELF loader can be 50 line long. Moreover, I won't integrate another object or executable format in TinyCC if it is not a standard one.
