[LLVMdev] MachO non-external X86_64_RELOC_UNSIGNED
Hello everybody,
I would like some insights on the semantics of the X86_64_RELOC_UNSIGNED
relocation type. When r_extern=1, the semantics seem pretty clear:
Let x be a pointer to r_offset of appropriate size given by r_size, then
*x += addr_of_symbol(r_symbolnum)
However, when r_extern=0 the correct behavior is not clear. By analogy with
the above, I would have expected
*x += addr_of_section(r_symbolnum)
but what...
