It shouldn't be too different from what is there already. Although we have a "static" and "dynamic" generator, the dynamic generator is perfect for generating relocatable code which can then be linked into a static executable. > Slink has a naive three-region model for assembler output.

For my simple tests I have managed with a .text and .data segment (plus a list of relocations and a symbol table). I haven't implemented any initializers for static variables like you have though.
