.reloc offset, reloc_name[, expression]
Generate a relocation at offset of type reloc_name with value expression. If offset is a number, the relocation is generated in the current section. If offset is an expression that resolves to a symbol plus offset, the relocation is generated in the given symbols section. expression, if present, must resolve to a symbol plus addend or to an absolute value, but note that not all targets support an addend. e.g. ELF REL targets such as i386 store an addend in the section contents rather than in the relocation. This low level interface does not support addends stored in the section.
