For gold the -Ttext option sets the address of the text segment, not the .text section. When I try your test case with current gold the text segment does indeed start at 0x8200, as expected.

That difference with BFD is annoying. In GRUB we need to use the exact address for .text. > Ian > -- Regards Vladimir 'φ-coder/phcoder' Serbinenko signature.asc Description: OpenPGP digital signature ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
