So the above generates absolute relocations of type R_X86_64_64
Relocation section '.rela.data.rel.local' at offset 0x5c18 contains 6 entries: Offset Info Type Sym. Value Sym. Name + Addend 000000000000 000200000001 R_X86_64_64 0000000000000000 .text + 10 000000000008 000200000001 R_X86_64_64 0000000000000000 .text + 30 000000000010 000200000001 R_X86_64_64 0000000000000000 .text + 50 000000000018 000200000001 R_X86_64_64 0000000000000000 .text + 0 000000000020 000200000001 R_X86_64_64 0000000000000000 .text + 20 000000000028 000200000001 R_X86_64_64 0000000000000000 .text + 40
and the linker doesn't like them probably because of the mcmodel we use but I need to talk to toolchain folks first to make sense of what's going on...
Thx.
