I don't know if it is possible on amd64. This extract from contrib/binutils/ld/ChangeLog-0001 is hopefully better worded: 2000-07-27 Ivan Kokshaysky * emulparams/elf64alpha.sh: Implement "-taso" emulation specific option to fit 64-bit executable in the lower 31-bit address range. This is done by changing start address of .interp (the very first section of executable) and then setting EF_ALPHA_32BIT elf header flag. This stuff could be useful to have a native OpenOffice, for example. -- Francois Tigeot
